The SafeGuard Management Center provides for serving multiple databases and domains by way of tenant-specific configurations (Multi Tenancy). You are able to administrate different SafeGuard Enterprise Databases and maintain different configurations. These configurations can also be exported to and imported from files to ease configuration. The SafeGuard Management Center does not need to be necessarily installed on one computer only. It can be installed on any computer on the network from which the databases can be accessed. Only privileged users - security officers - can access the SafeGuard Management Center. Several Security Officers can work with the data simultaneously. 3 SafeGuard® Enterprise 5.50, Administrator help 1.1 Logon to the SafeGuard Management Center When installing and configuring SafeGuard Enterprise, all essential configuration settings are carried out and an account is created for a Master Security Officer. This account is required the first time you log on to the SafeGuard Management Center. To start the Management Center, the user needs to know the password for the certificate store and have the certificate’s private key. For further information see the Installation Manual. Logon depends on whether you run the SafeGuard Management Center in Single Tenancy or in Multi Tenancy mode. 1.1.1 Logon in Single Tenancy mode 1. Start the SafeGuard Management Center via the Start menu. You will see a logon dialog. 2. Log on as an MSO and enter the certificate store password specified during initial configuration. Click OK. Note: If you enter an incorrect password, an error message will be displayed and a delay will be imposed for the next logon attempt. The delay period will be increased with each failed logon attempt. Failed attempts will be logged. The SafeGuard Management Center is opened. 4 SafeGuard® Enterprise 5.50, Administrator help 1.1.2 Logon in Multi Tenancy mode The Logon process to the Management Center is extended when you have configured several databases (Multi Tenancy), see Working with multiple database configurations on page 20. 1. Start the SafeGuard Management Center via product folder of the Start menu. The Select Configurations dialog will be displayed. 2. Select the database configuration you want to use from the drop-down list and click OK. The selected database configuration is connected to the Management Center and will become active. 3. To authenticate to the SafeGuard Management Center you are prompted to select the Security Officer name for this configuration and to enter their certificate store password. Confirm with OK. The SafeGuard Management Center will be opened and connected to the selected database configuration. Note: If you enter an incorrect password, an error message will be displayed and a delay will be imposed for the next logon attempt. The delay period will be increased with each failed logon attempt. Failed attempts will be logged. 5 SafeGuard® Enterprise 5.50, Administrator help 2 Operating steps in the SafeGuard Management Center The following steps are essential for working with SafeGuard Enterprise to ensure that the companywide security policies can be applied to the endpoint computers: Create or import the organizational structure. Create additional security officers. Define initial (principal) policy items. Save to the database. Export and import configurations. Day-to-day use After logging on for the first time, settings can be added as required. The various security officers can perform actions in accordance with the roles assigned to them. If new settings are saved to the database, they can be transferred to the endpoint computers where they become active. 6 SafeGuard® Enterprise 5.50, Administrator help 2.1 The Management Center work area Navigation window Toolbar to select actions Navigation area Administrative objects Tabs to select different tasks or to display information Action area Displays depend on the selections in the navigation area A Associated views can contain essential elements or information for administration of the objects currently being processed Buttons for all administrative actions Navigation area The navigation area contains buttons for all administrative actions: Users & Computers To import groups and users from an active directory, from the domain or from an individual computer. Policies To create policy items. Keys & Certificates To manage keys and certificates. 7 SafeGuard® Enterprise 5.50, Administrator help Tokens To manage tokens and smartcards Security Officers To create new security officers or roles and define actions for which additional authorization is required. Reports Enables records to be created of all security-related events and their management. Navigation window Objects to be processed or which can be created are displayed in the navigation window (Active Directory objects such as OUs, users and computers, policy items,...) depending on the administrative task selection. Action area For defining settings for the objects selected in the navigation window. The action area contains various tabs with which objects are processed and settings are carried out. The action area also includes information about the selected objects. Associated views Additional objects and information as required are displayed in these views. They provide useful information for system administration and they make use of the system easier. For example, keys can be allocated using drag-and-drop objects. Toolbar Contains symbols for the different Management Center actions. Symbols are displayed as and when they are available for the selected object. After logon, the Management Center always opens with the view in which it was closed. 8 SafeGuard® Enterprise 5.50, Administrator help 3 Creating the organizational structure Users and computers can also be defined in SafeGuard Enterprise and do not have to be imported from the Active Directory. If there is no existing organizational structure, it can be quickly created in SafeGuard Enterprise along with a structure for managing policy items. It is also possible to assign policies and/or encryption rules to local users. A security officer with the respective rights can set up workgroups or domains which have not yet been imported in order to manage the automatically registered users and computers. New users/computers logging on to SafeGuard Enterprise are displayed under their corresponding containers after initial synchronization with the database in the SafeGuard Management Center. The security officers can then manage them exactly the same as imported objects. The directory for these users/computers, .Auto registered, is automatically created in the root directory and under each domain/workgroup. It cannot be renamed or moved. Objects assigned to this directory cannot be moved manually either. 9 SafeGuard® Enterprise 5.50, Administrator help 3.1 Registering as a new user For logging on as a new user, see Power-on Authentication (POA) on page 178. When a new user logs on to SafeGuard Enterprise for the first time, their database status is checked during the initial synchronization with the database and the new object is displayed under the respective container in accordance with the information in the database. If no new workgroup or domain has been created, the new user is added in Auto.registered under the Root directory. If a domain has already been created, but the user/computer has not yet been imported, they are added in Auto.registered under the domain. Note: Local users cannot log on to SafeGuard Enterprise with an empty password. Local users who log on to SafeGuard Enterprise with an empty password remain as guests and are not saved to the database. If, in addition, Windows Autologin is activated for these users, logon is denied to them. For a successful logon at SafeGuard Enterprise a new password must be created in this case and the Windows Autologin must be deactivated in the registry of the endpoint computer. Logon information about the local object Database status Displayed in the Management Center Local users Local users not known Under master directory, .Auto registered newly added under its computer Local users, computers + domains Domain nodes known Users/computers present Already present under domain nodes Domain nodes known Users/computers not present .Auto registered newly added under domain nodes 10 SafeGuard® Enterprise 5.50, Administrator help Logon information about the local object Database status Displayed in the Management Center Computer workgroups + workgroup Workgroup known Users/computers not physically present Already present under workgroup Workgroup known Name of computer workgroups present under .Auto registered Newly added under .Auto registered workgroup Caution: In this case you need to check whether the Computer workgroups are present twice in the workgroup. To differentiate between identical computers, go to Properties and enter the Description. We recommend however that you manually remove the computer from the .Auto registered workgroup directory. Workgroup known Users/computers not present Newly added under .Auto registered workgroup Workgroup not known Computer workgroups known under .Auto registered root directory Already present under Root directory, .Auto registered Workgroup not known Computer workgroups not known under .Auto registered root directory Newly added under .Auto registered root directory Domain known Computer domains present Already present under domain Domain not known Newly added under .Auto registered root directory Domain not yet synchronized Newly added under .Auto registered domain Computer domains + domain 11 SafeGuard® Enterprise 5.50, Administrator help 3.2 Sample use cases for auto-registration Below you find two use cases on the behavior of auto-registered objects. Use case 1: Administrating users/computers not part of an Active Directory In a company not all user or computer objects might necessarily be part of an Active Directory (AD), e.g. local users. A company might have one or few workgroups so that an AD is not needed. This company wants to deploy SafeGuard Enterprise and then add policies to its user/ computer objects. Therefore the company's organizational structure will be built up manually in the SafeGuard Management Center as follows: Users & Computers tree: Root |_.Authenticated Computers |_.Authenticated Users |_.Auto registered |_SampleWorkgroup (entry added manually) |_.Auto registered |_SampleComputer001 (entry created on logon) |_SampleComputer002 (entry created on logon) |_... The user and computer objects remain in the .Auto registered folder. But they can be administered properly with the SafeGuard Management Center (adding or removing policies etc). 12 SafeGuard® Enterprise 5.50, Administrator help Use case 2: SafeGuard Enterprise Database and Active Directory out of sync A user and computer (SafeGuard Enterprise client) are already part of the company's Active Directory (AD). But the SafeGuard Enterprise database and the AD are out of sync: user and computer are not listed in the SafeGuard Management Center yet. The user logs on to the computer (SafeGuard Enterprise client) with the following credentials: SampleUser SamplePassword Sample Domain This information is sent to the SafeGuard Enterprise Server. In the SafeGuard Management Center the following entries are created: Users & Computers tree: Root |_.Authenticated Computers |_.Authenticated Users |_.Auto registered |_SampleDomain (entry created on sync with AD) |_.Auto registered |_SampleComputer (entry created on logon) |_SampleUser (entry created on logon) Upon the next synchronization between the AD and the SafeGuard Enterprise database the SampleComputer and the SampleUser are moved automatically to their correct organizational units (OU). The MSO can add policies to the .Auto registered folder if desired, but those policies will apply to SampleComputer and SampleUser only as long as those objects are part of the .Auto registered folder. Once they are moved to their organizational units (OU) by synchronization between the AD and the SafeGuard Enterprise Database, the policies set for those OUs will apply to SampleComputer and SampleUser as well. 13 SafeGuard® Enterprise 5.50, Administrator help 3.3 Keys and certificates for auto-registered objects A certificate is produced as required by the server for each auto-registered object. A local user gets two keys: the key to the .Auto registered container the private key generated as required by the server Local users neither get other keys for their assigned container nor a root key. Workgroups do not get a key. 3.4 Policies for auto-registered objects Unlimited policies can be created for auto-registered objects. Local users are added to the “Authenticated Users” group. Computers are added to the “Authenticated Computers” group. The policies activated for these groups apply accordingly. 3.5 Creating new workgroup Security officers with the respective rights assigned can create a container under the root directory which represents a Windows workgroup. Workgroups do not have a key. They cannot be renamed. 1. In the SafeGuard Management Center, click Users & Computers. 2. Right-click Root [filter is active] in the navigation window on the left and select New > Create new workgroup (auto registration). 3. In Common information enter the following: a) Enter a Full name for the workgroup. b) Optionally you can add a description of the workgroup. c) The type of object is displayed under Connection state, in this case Workgroup . d) To prevent policy inheritance, you may activate Block Policy Inheritance. e) Confirm details with OK. The workgroup is now created. The default .Auto registered directory is automatically created under the workgroup container. It cannot be renamed or deleted. 14 SafeGuard® Enterprise 5.50, Administrator help 3.6 Deleting workgroups Security officers can delete workgroups. Members assigned to the workgroup are also deleted. They are automatically re-registered at next logon. 1. In the SafeGuard Management Center click Users & Computers. 2. In the navigation window on the left right-click the workgroup you want to delete and select Delete. Confirm with Yes. The workgroup is now deleted. Any members are also deleted. 3.7 Creating a new domain Security officers with the respective rights can create a new domain under the root directory. You only have to create a new domain, if you do not want to or are not able to import a domain from the Active Directory (AD), for instance because there is no AD available. 1. In the SafeGuard Management Center click Users & Computers. 2. Right-click Root [filter is active] in the navigation window on the left and select New > Create new domain (auto registration). 15 SafeGuard® Enterprise 5.50, Administrator help 3. In Common information enter the following information about the domain controller . All three name entries must be correct otherwise the domain will not be synchronized: a) Full name: For example computer name.domain.com or the IP address of the domain controller b) Distinguished name: DNS name, for example DC=computername3,DC=domain,DC=country c) A description for the domain (optional) d) Domain Netbios: Name of the domain controller e) The type of object is displayed under Connection state, in this case Domain . f) To prevent policy inheritance, you may activate Block Policy Inheritance. g) Confirm details with OK. The new domain has now been created. Users and/or computers are automatically assigned to this domain during auto registration. The default .Auto registered directory is automatically created under the domain container. It cannot be renamed or deleted. 3.8 Renaming a domain A security officer with the respective rights can rename a domain and define additional properties. 1. In the SafeGuard Management Center click Users & Computers. 2. Right-click the domain you want to rename in the navigation window on the left and select Properties. 3. In Common information under Full name change the domain name and the description if required. 4. You may change the name of the domain controller in Domain NetBios. 5. You can also define the Wake on LAN mode for automatic reboot in the Container Settings tab. 6. Confirm with OK. The changes are now saved. 16 SafeGuard® Enterprise 5.50, Administrator help 3.9 Deleting a domain Security officers with the respective rights can delete domains. Members assigned to the domain are also deleted. 1. In the SafeGuard Management Center click Users & Computers. 2. In the navigation window on the left right-click the domain you want to delete and select Delete. Confirm with Yes. The domain is now deleted. Any members are also deleted. 3.10 Deleting auto registered computers When an auto-registered computer is deleted, all local users of this computer are also deleted. They are automatically re-registered the next time they log on to this computer. 3.11 Filter for local objects Users & Computers In Users & Computers you can filter the view in the navigation area on the left according to local users or search for specific local users. 1. In the SafeGuard Management Center click Users & Computers. 2. In the bottom left of the navigation window click Filter. 3. Activate Local user as Type. If you are looking for a specific user, enter the name of this user. 4. Click the magnifier icon. The Users & Computers view is filtered according to the criteria. Logging Successful/unsuccessful registration of the user, computer or workgroup is logged. You can view a list of this information in the SafeGuard Management Center under Reports in the event viewer. 17 SafeGuard® Enterprise 5.50, Administrator help 3.12 Importing the organizational structure from an Active Directory You have the option of importing an existing organizational structure to the SafeGuard Enterprise Database, e.g. via an Active Directory. 1. In the SafeGuard Management Center select Tools > Options. 2. Select the Directory tab and click Add. 3. In LDAP Authentication do the following: a) For Server name or IP enter the NetBIOS name of the domain controller or its IP address. b) For User credentials enter your Windows user name and password for the (test) environment. c) Confirm with OK.

If you want to make use of this feature you need to enable it during installation. For details see the SafeGuard Enterprise Installation manual. With Multi Tenancy you are able to configure different SafeGuard Enterprise Database configurations and maintain them for one instance of the SafeGuard Management Center. This is particularly useful when you want to have different configurations for different domains, organizational units or company locations. Prerequisite: The feature Multi Tenancy must have been installed via a Custom installation. Initial configuration must have been carried out. For details see the SafeGuard Enterprise Installation manual. To ease configuration the following is possible: Create multiple database configurations. Select from a list of previously created database configurations. Import a previously created database configuration from a file. Export a database configuration to be reused at a later point in time. 20 SafeGuard® Enterprise 5.50, Administrator help 4.1 Creating further database configurations To create a further SafeGuard Enterprise Database configuration after initial configuration, proceed as follows: 1. Start the SafeGuard Management Center. The Select Configuration dialog will be displayed. 2. Click New. The SafeGuard Management Center Configuration Wizard starts automatically. 3. The Wizard will guide you through the necessary steps of creating a new database configuration. Make your settings as required. The new database configuration will be generated. 4. To authenticate to the SafeGuard Management Center you are prompted to select the Security Officer name for this configuration and to enter their certificate store password. Confirm with OK. The SafeGuard Management Center will be opened and connected to the new database configuration. When the SafeGuard Management Center is started for the next time, the new database configuration can be selected from the list. 4.2 Connecting to an existing database configuration To work on an existing SafeGuard Enterprise Database configuration, proceed as follows: 1.

In Database Connection, select the relevant database server and configure the connection to the database if required. Click Next. 3. In Database Settings activate Select an available database and select the relevant database from the list. 4. In Security Officer Data, do either of the following: If the backed up certificate file can be found on the computer, it will be displayed. Enter the password you use for authenticating at the SafeGuard Management Center. If the backed up certificate file cannot be found on the computer, click Import. Browse for the backed up certificate file and confirm with Open. Enter the password for the selected certificate file. Confirm with Yes. Enter and confirm a password for authenticating at the SafeGuard Management Center. 5. Click Next and then Finish to complete the SafeGuard Management Center configuration. The corrupt SafeGuard Management Center installation is restored. 26 SafeGuard® Enterprise 5.50, Administrator help 5.4 Restoring a corrupt database configuration A corrupt database configuration can be restored by installing the SafeGuard Management Center afresh to create a new instance of the database based upon the backed up certificate files. This will ensure that all existing SafeGuard Enterprise endpoint computers still accept policies from the new installation. This avoids having to set up and restore the whole database afresh. The company and Master Security Officer certificates of the relevant database configuration must have been exported to .p12 files and must be available and valid. The passwords for the two .p12 files as well as for the certificate store must be known to you. Do the following: 1. Install the SafeGuard Management Center installation package afresh. Open the SafeGuard Management Center. The Configuration Wizard is started automatically. 2. In Database Connection, check Create a new database. Under Database settings, configure the connection to the database. Click Next. 3. In Security Officer Data, select the relevant MSO and click Import. 4. In Import Authentication Certificate browse for the backed up certificate file. Under Key file enter and confirm the password specified for this file. Confirm with OK. 5. The MSO certificate is imported. Click Next. 6. In Company Certificate, check Restore using an existing company certificate. Click Import to browse for the backed up certificate file that contains the valid company certificate. You are prompted to enter the password specified for the certificate store. Enter the password and confirm with OK. Confirm the message with Yes. The company certificate is imported. 7. Click Next, then Finish. The database configuration is restored. 27 SafeGuard® Enterprise 5.50, Administrator help 6 Licenses To use the SafeGuard Enterprise Management Center as a live system, you need a valid license. For example, in the SafeGuard Enterprise database, a valid license is a prerequisite for sending policies to the endpoint computers. The appropriate token licenses are also needed for token management. License files are obtained from your sales partner. These files must be imported into the SafeGuard Enterprise database after installation. The license file contains: data about the number of licenses purchased per module/name of the licensee and a specified tolerance limit for exceeding the number of licenses. If the number of available licenses or the tolerance limit is exceeded, relevant warning/error messages are displayed when you start the SafeGuard Management Center (see License exceeded on page 32). In the Users & Computers area, the SafeGuard Management Center provides an overview of the license status of the installed SafeGuard Enterprise system. The license status display is available in the Licenses tab for the root node, for domains, OUs, container objects and workgroups. Here security officers will find detailed information about the license status and can, if they have the appropriate permission, import licenses to the SafeGuard Enterprise database. This chapter describes the licensing concept and how to manage licenses in the SafeGuard Management Center. 6.1 License file The license file that you are given to import to the SafeGuard Enterprise database is an .XML file with a signature. The license file includes the following information: Company name Additional information (for example, department, subsidiary) Date issued Versions of SafeGuard Enterprise for which the license is valid. Number of licenses per module Token license information License expiry date License type (demo or full license) Signature with license signature certificate 28 SafeGuard® Enterprise 5.50, Administrator help 6.2 Token licenses To manage tokens or smartcards the appropriate token licenses are required. If the appropriate licenses are not available, creating polices for tokens in the SafeGuard Management Center is not possible. 6.3 Evaluation and demo licenses The default license file (evaluation license) or individual demo license files can be used for evaluation or initial rollout. These licenses are time sensitive and have an expiration date. However, there are no functional restrictions. Note: Evaluation and demo licenses may not be used for normal live operation. 6.3.1 Default license file When the SafeGuard Enterprise Management Center is installed, a default license file is automatically loaded. This evaluation license (named SafeGuard Enterprise Evaluation License) holds five licenses for each module and it has a time limit of two years as of the release date of the SafeGuard Enterprise version in question. 6.3.2 Individual demo license files If the default license file is insufficient for carrying out an evaluation, there is also the option of obtaining a demo license customized to your specific needs. In such a case, please contact your sales partner. The usage of this type of demo license is also subject to a time limit. The license is also restricted to the number of licenses per module agreed upon with your sales partner in the individual case. When you start the SafeGuard Management Center, a warning message reminds you that you are using demo licenses. If the number of available licenses specified in the demo license is exceeded, or if the time limit is reached, an error message is displayed, see License exceeded on page 32. 29 SafeGuard® Enterprise 5.50, Administrator help 6.4 License status overview You access the license status overview as follows: 1. In the SafeGuard Management Center navigation area, click Users & Computers. 2. In the navigation window, on the left-hand side, click on the root node, the domain, the OU, the container object or the workgroup. 3. In the action area, switch to the Licenses tab on the right-hand side. The license status appears. The display is divided into three areas. The upper area shows the name of the customer for whom the license has been issued, plus the issue date. The middle area provides details of the license. The individual columns contain the following details: Column Explanation Status (icon) Uses an icon to show the status of the licenses (valid, warning, error) for the module in question. Feature Shows the installed module. Purchased Licenses Shows the number of licenses purchased for the installed module. 30 SafeGuard® Enterprise 5.50, Administrator help Column Explanation Used Licenses Shows the number of licenses used for the installed module.

If you display tab Licenses for a domain/OU, the overview shows the status based on the computer in the relevant branch. Beneath this overview are details of the licensed token modules. In the lower area, a message with a background color based on the traffic light principle (green = valid, yellow = warning, red = error) and an icon shows the global status of the license regardless of the domain or OU selected. In case of warning or error messages, the lower area also offers information on how to regain a valid license status. The icons in the middle and lower areas mean the following: Valid license Invalid license: Warning Invalid license: Error For information about a license status with a warning or an error, see License exceeded on page 32. To refresh the license status overview, click Recount used licenses. 31 SafeGuard® Enterprise 5.50, Administrator help 6.5 Importing license files Prerequisite: To import a license file to the SafeGuard Enterprise database a security officer needs the "Import license file" permission. A license file is imported as follows: 1. You have the Management Center open, in the Users & Computers area. 2. In the navigation window, on the left-hand side, click the root node, the domain or the OU. 3. In the Action area, switch to the Licenses tab on the right-hand side. 4. Click the Import License File button. A window opens allowing you to select the license file. 5. Select the license file you want to import, and click Open. 6. An overview of the contents of the new license file is displayed. Confirm that you wish to import the license file. The license file has now been imported to the SafeGuard Enterprise database. After importing a license file, the module licenses purchased are marked with the license type regular. Any modules for which no licenses were purchased and for which the evaluation license (default license file) or individual demo licenses are used are marked with license type demo. Note: Whenever a new license file is imported, only those modules that are included in this license file are affected. All other module license information is retained as is from the database. This import behavior simplifies subsequent evaluation of additional modules after you have already purchased one or more modules. 6.6 License exceeded A tolerance value has been set in your license file for exceeding the number of licenses purchased and the license validity period. If the number of available licenses per module or the validity period is exceeded, first of all a warning message is displayed. This does not impact the system's live operation and, in this case, no restriction on its functionality takes effect. You now have the opportunity to review the license status and upgrade or renew your license. The tolerance value is usually set to 10% of the number of licenses purchased (minimum value: 5, maximum value: 5,000). 32 SafeGuard® Enterprise 5.50, Administrator help If the tolerance value is exceeded, an error message is displayed. In this case, a restriction is placed also on the functionality; the deployment of policies to the endpoint computers is disabled. This cannot be manually reversed in the SafeGuard Management Center. The license has to be upgraded or renewed before you can use the full functionality once more. Apart from disabling policy deployment, the functional restriction does not have an impact on the endpoint computers, and policies already assigned remain active. Also, clients can still be uninstalled despite the disabling of policy distribution. The following sections describe how the system behaves in the case of licenses being exceeded in the categories Warning and Error, and the action that needs to be taken to reverse the functional restriction. 6.6.1 Invalid license: Warning If the number of available licenses (or the highest permitted SafeGuard Enterprise version, for example due to a software update) is exceeded, a warning message appears when you start the SafeGuard Management Center. The SafeGuard Management Center opens and displays the license status overview in the Licenses tab in the Users & Computers area. A warning message tells you that the license is invalid. Using the detailed information shown about the license file you can determine for which module the number of available licenses has been exceeded. This license status can be reversed by extending, renewing or upgrading the license, see Invalid license: Error on page 34. 33 SafeGuard® Enterprise 5.50, Administrator help 6.6.2 Invalid license: Error If the tolerance value for the number of licenses or the period of validity set in the license is exceeded, the SafeGuard Management Center displays an error message. In the SafeGuard Management Center, the deployment of policies to the endpoint computers is disabled. An error message is also displayed in the Licenses tab in the Users & Computers area. Using the detailed information shown about the license file you can determine for which module the number of available licenses has been exceeded. You have the following options for reversing the functionality restriction: Redistribute licenses In order that you have enough available licenses, you can uninstall the software on unused computers and thereby remove the computers from the SafeGuard Enterprise database. Upgrade/renew licenses Contact your sales partner to get your license upgraded or renewed. You will be given a new license file to import to the SafeGuard Enterprise database. 34 SafeGuard® Enterprise 5.50, Administrator help Import new license file If you have renewed or upgraded your license, you can import the license file you receive to the SafeGuard Enterprise database. The newly imported file replaces the invalid license file. When you redistribute licenses or import a valid license file, the functional restriction is reversed and the system will continue to run normally. 35 SafeGuard® Enterprise 5.50, Administrator help 7 SafeGuard Enterprise Security Officers SafeGuard Enterprise can be administered by one or more security officers. The role-based management of SafeGuard Enterprise allows splitting the administration among several users. Any user may be assigned one or more roles. To enhance security additional authorization of an action can be assigned to an officer’s role. A top-level administrator, the Master Security Officer (MSO) with all the rights and a certificate that does not expire is created by default during initial configuration of the SafeGuard Management Center. Further security officers can then be assigned for specific tasks such as helpdesk or auditing. For your convenience, security officers can be hierarchically arranged in the SafeGuard Management Center navigation area to reflect your company’s organizational structure. However, this does not imply any hierarchy in terms of rights and roles. 7.1 Security Officer roles For easy operation SafeGuard Enterprise offers already predefined roles for security officers with a variety of functions. Additionally, a security officer with the necessary rights can define new roles from a list of actions/rights and assign them to particular security officers. The following types of roles are provided: Master Security Officer (MSO) role Predefined roles Customized roles 7.1.1 Master Security Officer After installing SafeGuard Enterprise, a Master Security Officer (MSO) is created by default during initial configuration of the SafeGuard Management Center. The Master Security Officer is the top-level security officer and possesses all the rights and is able to access all objects, i.e. comparable to a Windows administrator. The Master Security Officer rights cannot be modified. There may be several Master Security Officers created for one instance of the SafeGuard Management Center. We strongly recommend to create at least one additional MSO for security reasons. Additional MSOs may be deleted, but there must always remain one user with the role of MSO who has been explicitly created as MSO in the SafeGuard Enterprise Database. 36 SafeGuard® Enterprise 5.50, Administrator help A Master Security Officer can delegate tasks to another person. There are two ways to do this: A new security officer can be created in Security Officers. A user or all members of a container imported from the Active Directory and visible in the SafeGuard Management Center in the root directory can be promoted to security officer in Users and Computers. One or more roles and domains can then be assigned to them. For example, a user may be assigned the role of Supervising Officer plus the role of Helpdesk Officer. However, the Master Security Officer can also create custom roles and assign them to particular users. 7.1.2 Predefined roles In the SafeGuard Management Center, the following security officer roles, apart from the MSO, are predefined. The assignment of rights to these predefined roles cannot be changed. For example, if a predefined role has the right to “Create policy items and policy groups”, this right cannot not be deleted from the role. Neither can a new right be added to a predefined role. Additional officer authentication however, may be assigned to predefined roles at any point in time. Supervising Officer Supervising Officers are able to see their own node in the Security Officer area and have the right to manage security officers belonging to their node. Security Officer Security Officers dispose of extensive rights including SafeGuard Enterprise configuration, policy and key management, permissions for monitoring and recovery. Helpdesk Officer Helpdesk Officers have the rights to perform recovery actions. Additionally they may display most function areas of the SafeGuard Management Center. Audit Officer To be able to monitor SafeGuard Enterprise, Audit Officers may display most function areas of the SafeGuard Management Center. Recovery Officer Recovery Officers have the rights to repair the SafeGuard Enterprise Database. 37 SafeGuard® Enterprise 5.50, Administrator help 7.1.3 Customized roles As a security officer equipped with the necessary rights you can define new roles from a list of actions/rights and assign them to an existing or new security officer. As with predefined roles, you may enable the additional officer authentication for a function of the role at all times. When assigning a new role, note the following regarding additional authentication: Note: If a user has two roles with the same rights assigned and additional authentication is assigned to one of the roles, this automatically applies to the other role. A security officer equipped with the necessary rights may add or delete rights to or from a custom role. Unlike predefined roles, custom roles can even be deleted, as required. If the roles is deleted, it is no longer assigned to any user. If a user only has one role assigned and this role is deleted, the user is not able to log on to the SafeGuard Management Center any more. Note: The role and the actions defined within it determine what a user may and may not do. This is also true if the user has been assigned more than one role. After the user has logged on to the Management Center only those areas are activated and displayed that are needed to perform their role. This also applies to the scripts and API areas. It is therefore important to always activate displaying the area in which the respective actions are defined. Actions are sorted by function area and are hierarchically structured. This structure shows which actions are required before certain other actions can be performed. 7.1.4 Additional officer authentication Additional officer authentication (also referred to as two persons rule) may be assigned to specific actions of a role. This means that the user of this role is only permitted to perform a certain action if a user of another role is present and confirms the performance of this action. Additional authentication may be assigned to predefined or custom roles alike. As soon as there are at least two officers with the same role, also the own role can be selected. The role which is to perform the additional authorization must have been assigned to a user and there need to be at least two security officers in the SafeGuard Enterprise Database. Once additional authentication is required for an action, it is required no matter if the user owns another role that does not require additional authentication for this action. If an officer without the right to change the additional authentication creates a role, settings for additional authentication of the new role will be pre-filled to match those set for the creating officer. Note: Two security officers must not use the same Windows account on the same PC. Otherwise it is not possible to separate their access rights properly. Additional authentication may only be useful when security officers must authenticate via cryptographic tokens/smartcards. 38 SafeGuard® Enterprise 5.50, Administrator help 7.2 Creating a role Prerequisite: To create a new role, you need the right to display and create security officer roles. To assign additional authentication you need the right to "Change additional authentication settings". Do the following: 1. In the SafeGuard Management Center select Security Officers. 2.

If you are working in Multi Tenancy mode you will be logged on to the same database configuration. The SafeGuard Management Center is restarted displaying the view assigned to the logged on officer. 7.16 Deleting a security officer Prerequisite: To delete a security officer or Master Security Officer, you need the right to display and delete security officers. Do the following 1. In the SafeGuard Management Center select Security Officers. 2. In the navigation window, right-click the security officer or Master Security Officer you want to delete and select Delete. Note that you cannot delete the officer you are logged on with. 3. If the officer has children you are prompted to select a new parent node for the children. The officer is deleted from the database. Note: One Master Security Officer explicitly created as an officer and not only promoted to security officer must always remain in the database. If a user promoted to security officer is deleted from the database, their user account is deleted from the database as well. Note: If the officer to be deleted has been assigned a role that includes additional authentication and the officer is the only one this role is assigned to, the officer will be deleted nonetheless. It is assumed that the Master Security Officer will be able to take over additional authorization. 54 SafeGuard® Enterprise 5.50, Administrator help 8 Data encryption The core of SafeGuard Enterprise is the encryption of data on different data storage devices. Encryption can be volume or file-based with different keys and algorithms. Files are encrypted transparently. When users open, edit and save files, they are not prompted for encryption or decryption. As a security officer, you specify the settings for encryption in a security policy of the type Device Protection. 8.1 Volume-based encryption With volume-based encryption, all data on a volume (including boot files, pagefiles, hibernation files, temporary files, directory information etc.) are encrypted. Users do not have to change normal operating procedures or consider security. Note: If an encryption policy exists for a volume or a volume type and encryption of the volume fails, the user is not allowed to access it. To apply volume-based encryption to endpoint computers, create a policy of the type Device Protection and set the Media encryption mode toVolume-based. 8.1.1 Fast initial encryption SafeGuard Enterprise offers fast initial encryption as a special mode for volume-based encryption. It reduces the time needed for initial encryption (or final decryption) of volumes on endpoint computers by accessing only disk space that is actually in use. For fast initial encryption, the following prerequisites apply: Fast initial encryption only works on NTFS-formatted volumes. NTFS-formatted volumes with a cluster size of 64 KB cannot be encrypted with the fast initial encryption mode. Note: This mode leads to a less secure state if a disk has been used before its current usage with SafeGuard Enterprise. Unused sectors may still contain data. Fast initial encryption is therefore disabled by default. To enable fast initial encryption, select the setting Fast initial encryption in a policy of the type Device Protection. Note: For volume decryption, the fast initial encryption mode will always be used, regardless of the specified policy setting. For decryption, the prerequisites listed also apply. 55 SafeGuard® Enterprise 5.50, Administrator help 8.1.2 Volume-based encryption and Windows 7 system partition For Windows 7 Professional, Enterprise and Ultimate, a system partition is created on endpoint computers without a drive letter assigned. This system partition cannot be encrypted by SafeGuard Enterprise. 8.1.3 Volume-based encryption and Unidentified File System Objects Unidentified File System Objects are volumes that cannot be clearly identified as plain or deviceencrypted by SafeGuard Enterprise. If an encryption policy exists for an Unidentified File System Object, access to this volume will be denied. If no encryption policy exists, the user can access the volume. Note: If an encryption policy with Key to be used for encryption set to an option that enables key selection (for example, Any key in user key ring) exists for an Unidentified File System Object volume, there is a period of time between the key selection dialog being displayed and access being denied. During this time period the volume can be accessed. As long as the key selection dialog is not confirmed, the volume is accessible. To avoid this, specify a preselected key for encryption. This period of time also occurs for Unidentified File System Object volumes connected to an endpoint computer, if the user has already opened files on the volume when an encryption policy takes effect. In this case, it cannot be guaranteed that access to the volume will be denied as this could lead to data loss. 8.1.4 Encryption of volumes with enabled Autorun functionality If you apply an encryption policy to volumes for which Autorun is enabled, the following can occur: The volume is not encrypted. If the volume is an Udentified File System Object (see Volume-based encryption and Unidentified File System Objects, page 56), access is not denied. 8.1.5 Access to BitLocker To Go encrypted volumes If SafeGuard Enterprise is used with BitLocker To Go support enabled and a SafeGuard Enterprise encryption policy exists for a BitLocker To Go encrypted volume, access to the volume will be denied. If no SafeGuard Enterprise encryption policy exists, the user can access the volume. Note: If the Autorun settings for a BitLocker To Go encrypted USB stick are set to the default values, it can occur that access will not be denied although a SafeGuard Enterprise encryption policy exists. This only occurs under Windows Vista. 56 SafeGuard® Enterprise 5.50, Administrator help 8.2 File-based encryption File-based encryption ensures that all data is encrypted, apart from Boot Medium and directory information. With file-based encryption, even optical media such as CD/DVD can be encrypted. Also, data can be exchanged with external computers on which SafeGuard Enterprise is not installed, if policies permit. Note: Data encrypted using “file-based encryption” cannot be compressed. Nor can compressed data be file-based encrypted. Note: Boot volumes are never file-based encrypted. They are automatically exempted from filebased encryption, even if a corresponding rule is defined. To apply file-based encryption to endpoint computers, create a policy of the type Device Protection and set the Media encryption mode to File-based. 8.2.1 Excluding applications from encryption You can define applications to be ignored by the SafeGuard Enterprise filter driver and thereby excluded from transparent encryption/decryption. One example is a backup program. To ensure that data is not decrypted when creating a backup, this application can be exempted from encryption/decryption. The data is backed up in encrypted form. A typical use case is for example to define backup programs as exempted so they will always be able to read and back up encrypted data. Applications which might trigger malfunctions when used alongside SafeGuard Enterprise, but do not require encryption, can generally be exempted from encryption. You can define applications to be excluded from encryption/decryption in a policy of the type Device Protection with the target Local Storage Devices. The full name of the executable file (optionally including path information) is used to specify Unhandled Applications. 57 SafeGuard® Enterprise 5.50, Administrator help 9 SafeGuard Enterprise Key Management When importing the directory structure, the standard version of SafeGuard Enterprise automatically generates keys for: Domains Containers/OUs Groups and assigns them to the corresponding objects. Computer and user keys are generated as required. Keys cannot be deleted! They are retained permanently in the SafeGuard Enterprise database. The first time a endpoint computer is booted, SafeGuard Enterprise generates a computer key for that computer (defined machine key). Each user obtains all their keys at logon from their user key ring. The user key ring comprises the following: A personal key the keys of the groups of which the user is a member the keys of the overall Container/OUs of the groups of which the user is a member. The keys in the user key ring determine the data which that user can access. The user can access only that data for which they have a specific key. To display all keys for a user, click Users & Computers and select the Keys tab. To display all keys, click Keys & Certificates in the SafeGuard Management Center. You can generate lists for Assigned Keys and Inactive Keys. 58 SafeGuard® Enterprise 5.50, Administrator help 3 4 2 1 1. Click Users & Computers to open the display 2.

Volumes are as follows: 60 SafeGuard® Enterprise 5.50, Administrator help When you carry out the settings for each media you are offered the option: Keys to be used for encryption. Here you decide which keys a user can or must use for encryption: 61 Any key in user key ring After logging on to Windows users can select which keys they would like to use to encrypt a particular volume. A dialog is displayed in which the user can select the required key. Any key in user key ring except user key A user may not use their own personal key to encrypt data. Any group key in user key ring The user may only select one of the group keys in their user key ring. Defined computer key is the unique key generated exclusively for this computer by SafeGuard Enterprise the first time this machine is booted up. The user has no other options. A defined computer key is typically used for the boot and system partition and for drives on which Documents and Settings are located. SafeGuard® Enterprise 5.50, Administrator help Defined key on list This option allows you to define a specific key which the user must use for encryption. To specify a key for a user in this way you need to define a key under Defined key for encryption (is displayed once you select Defined key on list). Click the [...] button next to the option Defined key for encryption to display a dialog in which you can specify a key. Ensure that the user is also in possession of the corresponding key when specifying keys in this way. Search here for key names or key IDs. Enter a search term. All matching keys are displayed here. Highlight the selected key and click OK. The selected key will be used for encryption on the endpoint computer. 9.2 Certificates SafeGuard Enterprise can be verified with signed SHA1, MD2 and MD5 certificates. If Certification Authority (CA) certificates are deleted in the database and you do not wish to use them again, you should remove these certificates manually from all Administrator PCs in the local store. SafeGuard Enterprise can then only communicate with expired certificates if old and new keys are present on the same card. 62 SafeGuard® Enterprise 5.50, Administrator help The combination of CA certificates and CRL (Certificate Revocation List) on a smartcard must match. Otherwise users cannot log on to the respective computers. Please check that the combination is correct. SafeGuard Enterprise does not carry out this check! The logon certificates for security officers must be located in “MY”. CA certificates cannot be obtained from a token and stored in the database or certificate store. If you wish (or need) to use CA certificates, these need to be available in file form and not just on a token. The same applies for CRLs. Note that, when importing a user certificate, the certificate's public and private sections are both imported. If only the public part is imported, only authentication with a token is supported. 9.3 Virtual Clients Virtual Clients are specific encrypted key files that can be used for recovery in a Challenge/ Response procedure when the required user information is not available and usually, Challenge/ Response would not be supported, for example when the POA is corrupted. To enable a Challenge/Response procedure in this complex disaster situation, specific files called Virtual Clients can be created and must be distributed to the user prior to the Challenge/Response session. Challenge/Response can then be initiated with the help of these Virtual Clients via a key recovery tool on the endpoint computer. The user then only needs to inform the helpdesk officer of the required key or keys and enter the response code in order to regain access to the encrypted volumes. Recovery is either possible with the help of a single key or by using an encrypted key file containing several keys. In the SafeGuard Management Center Keys & Certificates area you have the following possibilities: 63 Create and export Virtual Clients Create and export encrypted key files containing several keys Display and filter Virtual Clients and exported key files Delete Virtual Clients SafeGuard® Enterprise 5.50, Administrator help 9.3.1 Creating Virtual Clients Virtual Client files can be used by different computers and for several Challenge/Response sessions. 1.

Policy color black Policy is applied to machines and users 10.3 Policy groups SafeGuard Enterprise policies need to be combined in policy groups. A policy group may contain different policy types. If you sum up policies of the same type in a group, the settings will be merged automatically. In this case, you can define priorities for utilizing the settings. The settings of a policy with a higher priority overwrite the settings of a policy with a lower priority. If an option is set to not configured, the setting will not be overwritten in a policy of a lower priority. 69 SafeGuard® Enterprise 5.50, Administrator help Exception concerning device protection: Policies for device protection will only be merged, if they were defined for the same target (e.g. boot volume). If they point at different targets, the settings will be added. 10.3.1 Combining policies into groups The individual policies of different types must have been created beforehand. To group policies, do the following: 1. Click Policies in the navigation area. 2. in the navigation window, right-click Policy Groups and select New. 3. Click New Policy Group.

They apply by default to all groups in those container objects (.Authenticated users and .Authenticated computers groups are displayed in the activation area). However, you can also define policies and activate them for one or more groups. These policies then apply exclusively to these groups. To define a policy which is to apply only to a specific group, proceed as follows: 1.

When clicking the button, selecting the command or pressing F3, no policies will be sent to the endpoint computers. By clicking the button, selecting the command or pressing F3 again, you can reverse the disabling of policy deployment and policies will be sent again. Note: For disabling policy deployment, a security officer needs the right “Enable/disable policy deployment“. This right has been assigned by default to the predefined roles Master Security Officer and Security Officer. However, this right can also be assigned to new user-defined roles. 74 SafeGuard® Enterprise 5.50, Administrator help 10.8 Rules for assigning and analyzing policies The management and analysis of policies is carried out according to the rules outlined in this chapter. 10.8.1 Assigning and activating policies To enable a policy to be implemented for a user/computer, you need to assign it to a container object (root nodes, domain, OU, BuiltIn container or workgroup). For the policy assigned to the user/computer to become effective, when you assign a policy anywhere in the hierarchy, all computers (authenticated computers) and all users (authenticated users) are activated automatically (assignment without activation is not enough). All users and all computers are combined into these groups. 10.8.2 Policy inheritance Policies can only be passed between container objects. Only container objects can pass on policies from higher-ranking container objects. Policies can be activated within a container provided it contains no further container objects (at group level). There can be no inheritance between groups. 10.8.3 Policy inheritance hierarchy Where policies are assigned along a hierarchy chain, the policy implemented is the highest ranking; closest in the case of a target object (user/computer). This means that as the distance to the target object increases a policy will be superseded by policies which are closer. 10.8.4 Direct and indirect assignment of policies Direct assignment The user/computer obtains a policy which is assigned directly to the container object in which it is located (membership alone is not sufficient). The container object has not passed on this policy! Indirect assignment The user/computer obtains a policy which the container object in which it is actually located (membership as a user of a group located in another container object is not sufficient) has inherited from a higher-ranking container object. 75 SafeGuard® Enterprise 5.50, Administrator help 10.8.5 Activating/deactivating policies For a policy to be effective for a computer/user, it has to be activated at group level (policies can only be activated at group levels). It makes no difference if this group is in the same container object or not. All that matters here is that the user or computer has been directly or indirectly (through inheritance) assigned to the policy. If a computer or user is outside an OU or inheritance line and is a member of a group which is inside this OU, this activation does not apply to this user or computer. Because there is no valid assignment for this user or computer (directly or indirectly). The group was, indeed, activated but an activation can only apply to users and machines for which there is also a policy assignment. I.e. the activation of policies cannot go beyond container boundaries if there is no direct or indirect policy assignment for that object. A policy becomes effective when it has been activated for user groups or computer groups. The user groups and then the computer groups are analyzed (authenticated users and authenticated computers are also groups). Both results are OR-linked. If this OR-link gives a positive value for the computer/user relationship, the policy applies. Note: If more than one policy is active for an object the individual policies are, while complying with the rules described, merged. I.e. the actual settings for an object can be composed of multiple different policies. A group can have the following activation settings: Activated A policy has been assigned. The group is displayed in the activation area of the SafeGuard Management Center. Not activated A policy has been assigned. The group is not in the activation area. If a policy is assigned to a container, the activation setting for a group (activated) determines whether that policy for that container feeds into the calculation of the resulting policy. Inherited policies cannot be controlled by these activations. “Block policy inheritance” would have to be set at the more local OU so the more global policy cannot be effective here. 76 SafeGuard® Enterprise 5.50, Administrator help Example1: There is a valid assignment of policy P1 for the OU AUTHMANUELL and an activation for the group Auth-User-Group. Emil and Gunther are members of the Auth-User-Group group. Although user Gunther is also a member of the AuthUser-Group group, policy P1 does not apply to him but only to user Emil. As there is no valid assignment of policy P1 for user Gunther (user Gunther does not belong to the OU AUTHMANUELL) the activation of the Auth-User-Group group has no effect for him. Example 2 Structure of the ADs as on the right Policy P1 is assigned to the OU Auth-User and is effective only for the OU Auth-User and its sub-OUs For Authenticated Users and for Authenticated Computer , Policy P1 is NOT activated Policy P1 is only activated for the global group Global_Group (only user Gunther is a member of this group. The Global_Group itself is directly beneath the domain node.) Policy P1 is effective for user Gunther because he has received (indirectly) a valid assignment of the policy from the OU Auth-User . This example illustrates that the activation of a policy can be done anywhere in the Active Directory. All that matters here is that there is a valid assignment. 77 SafeGuard® Enterprise 5.50, Administrator help 10.8.6 User/group settings Policy settings for users (settings shown in black in the SafeGuard Management Center) take priority over policy settings for computers (settings shown in blue in the SafeGuard Management Center). If user settings are done in a policy for computers, those settings will be overridden by the policy for the user. Note: Only the user settings will be overridden. If a policy for users also includes machine settings (settings shown in blue), these will not be overridden by a user policy! Example 1: If password length 4 has been defined for a computer group, the user group is assigned value 3 for the same setting and this user is subject to password length 3 on a computer in the computer group. Example 2: If a server interval of 1 minute is defined for a user group, and the value 3 for a machine group, value 3 is used because value 1 minute is a machine setting which was defined in a policy for users. 10.8.7 Contradictory encryption policies Two policies - P1 and P2 - are created. File based encryption for Drive E:\ was defined for P1, and volume based encryption for Drive E:\ was defined for P2. P1 is assigned the OU FBE-User and P2 the OU VBE-User. Case 1: A user from OU FBE-User logs on first to the Client XP-100 (container computer). Drive E:\ is file based encrypted. If a user from the OU VBE-User then logs on to Client XP-100, Drive E:\ will be volume based encrypted. If both users have the same key, both can access the drives or files. Case 2: A user from OU VBE-User logs on first to the computer XP-100 (container computer). The drive is volume based encrypted. If, now, a user from OU FBE-User logs on and has the same key as users from OU VBE-User, Drive E:\ (the volume based encryption is kept) will be file based encrypted within the volume based encryption. However, if the user from OU FBE-User does not have the same key, they cannot access Drive E:\. 78 SafeGuard® Enterprise 5.50, Administrator help 10.8.8 Priority within an assignment The policy with the highest priority (1) ranks above a policy with a lesser priority within an assignment. Note: If a policy with a lesser priority but which has been designated “No override” is assigned to the same level as a higher ranking policy, this policy will take priority despite its lower ranking. 10.8.9 Priority within a group The policy with the highest priority (1) ranks above a policy with a lesser priority within a group. 10.8.10 Status indicators Setting status indicators allows the standard rules for policies to be changed. Block policy inheritance Set for containers for which you do not wish higher-ranking policies to apply (right-hand mouse click the object in the Properties navigation window). No Override Set during assignment process this policy cannot be overridden by another policy. Block Policy Inheritance If you do not want a container object to inherit a policy from a higher object, select “Block Policy Inheritance” to prevent this. If “Block Policy Inheritance” has been selected for a container object it will not be affected by higher-ranking policy settings (exception: “No Override” activated when policy was assigned). No Override The further away the policy assignment with “No Override” is from the target object, the stronger the effect of this policy for all the lower-ranking container objects will be. This means that a higher ranking container subject to “No Override” overrides the policy settings of a lower ranking container. So, e.g., a domain policy can be defined whose settings cannot be overridden, even if “Block policy inheritance” has been set for an OU! Note: If a policy with a lesser priority but which has been designated “No Override” is assigned to the same level as a higher ranking policy, this policy will take priority despite its lower ranking. 79 SafeGuard® Enterprise 5.50, Administrator help 10.8.11 Settings in policies Replay Machine Settings You will find this setting under: Policy Items > policy of the type General Settings > Loading of settings > Policy loopback If you select “Replay Machine Settings” in the field Policy Loopback of a policy of the type General Settings and the policy comes from a computer (“Replay Machine Settings” does not affect user policies), this policy is replayed at the end of the analysis. This then overrides any user settings and the machine settings apply. All machine settings inherited directly or indirectly by the machine (including policies which have not been applied by the “Replay Machine Settings” policy loopback) are rewritten. Ignore User You will find this setting under: Policy Items > policy of the type General Settings > Loading of Settings > Policy Loopback If you select “Ignore User” for a policy for a computer in the field Policy Loopback of a policy of the type General Settings and the policy comes from a machine, only the machines settings are analyzed.

No Loopback You will find this setting under: Policy Items > policy of the type General Settings > Loading of Settings > Policy Loopback No loopback describes the standard behavior. User policies take priority over computer policies. Analyzing the settings “Ignore User” and “Replay Machine Settings” If there are active policy assignments, the machine policies are analyzed and consolidated first. If, with the Policy Loopback option, this amalgamation of individual policies gives the value “Ignore User”, the policies that would have been fixed for the user will not be analyzed. This means that the same policies apply both for the user and for the machine. If, after amalgamating the individual machine policies, the value with the Policy Loopback attribute is “Replay machine settings”, the user policies are amalgamated with the machine policies. After the amalgamation, the machine policies are rewritten and, where appropriate, override settings from the user policies. If a setting is present in both policies, the machine policy value overrides the user policy value. If the consolidation of the individual machine policies results in the standard value (“No Policy Loopback”), user settings take priority over machine settings. 80 SafeGuard® Enterprise 5.50, Administrator help Order of the execution of policies Ignore User Computers Replay Machine Settings Computer -> User -> Computer The first “machine execution” is required for the policies which are written before user logon (e.g. background image at logon). No Loopback (standard setting): Computer -> User 10.8.12 Other definitions The decision as to whether it is a user or machine policy depends on the policy's origin. A user object “brings” a user policy, while a computer “brings” a computer policy. The same policy can be a machine or a user policy, depending on the perspective. User policy Any policy provided by the user for analysis. If a policy is implemented via only one user, the machine-related settings of that policy are not applied, i.e. computer-related settings do not apply. Default values do. Computer policy Any policy provided by the machine for analysis. If a policy is implemented via just one computer, the user-specific settings for this policy are also applied! The computer policy therefore represents a policy “for all users”. 81 SafeGuard® Enterprise 5.50, Administrator help 82 SafeGuard® Enterprise 5.50, Administrator help 11 Working with configuration packages In the SafeGuard Management Center you can create the following types of configuration packages: Configuration package for managed computers Computers that have a connection to the SafeGuard Enterprise Server receive their policies via this Server. For successful operation after installation of the SafeGuard Enterprise Client software, you need to create a configuration package for managed computers and deploy it to them. After the first configuration of the endpoint computer via the configuration package, the computer receives policies via the SafeGuard Enterprise Server after you have assigned them in the Users & Computer area of the SafeGuard Management Center. Configuration package for unmanaged computers Unmanaged computers are never connected to the SafeGuard Enterprise Server at any point in time, they operate in standalone mode. They receive their policies via configuration packages. For successful operation, you need to create a configuration package containing the relevant policy groups and distribute it to the endpoint computers via company distribution mechanisms. New configuration packages needs to be created and distributed to the endpoint computers whenever the policy settings are changed. Configuration package for the SafeGuard Enterprise Server For successful operation, you need to create a configuration package for the SafeGuard Enterprise Server, defining the database and SSL connection, enabling the scripting API and so on. For a detailed description on how to create the different kinds of configuration packages, see the SafeGuard Enterprise Installation manual. Note: Check your network and computers in regular intervals for outdated or unused configuration packages and, for security reasons, make sure to delete them. Always ensure to uninstall the “old” configuration packages before installing the new one on the computer/server. 83 SafeGuard® Enterprise 5.50, Administrator help 12 Administrative access options for endpoint computers To cater for access requirements for administrative tasks after the installation of SafeGuard Enterprise on endpoint computers, SafeGuard Enterprise offers the following administrative access options: Service accounts for Windows logon With service accounts, administrators can log on (Windows logon) to endpoint computers after the installation of SafeGuard Enterprise without activating the Power-on Authentication and without being added as users to the computers. Service accounts lists are defined in the Policies area of the SafeGuard Management Center and assigned via policies to the endpoint computers. Users included on a service account list are treated as guest users when logging on at the endpoint computer. Note: Service account lists are assigned to endpoint computers via policies. They should be assigned in the first SafeGuard Enterprise configuration package you create for the configuration of the endpoint computers. For detailed information on service accounts, see Service Account Lists for Windows logon, page 85. POA access accounts for POA logon on unmanaged endpoint computers protected by SafeGuard Enterprise For unmanaged endpoint computers, i.e., endpoint computers operating in standalone mode, SafeGuard Enterprise offers POA access accounts. POA access accounts are predefined local accounts that enable users to log on (POA logon) to endpoint computers after the Power-on Authentication has been activated to perform administrative tasks. The accounts are defined in the Users and Computers area of the SafeGuard Management Center (user ID and password) and assigned to the endpoint computers via POA access groups included in configuration packages. For detailed information on POA access accounts, see POA access accounts for POA logon at unmanaged endpoint computers, page 91. 84 SafeGuard® Enterprise 5.50, Administrator help 13 Service Account Lists for Windows logon A typical scenario for most implementations is that a rollout team installs new computers in an environment including the installation of SafeGuard Enterprise. For installation or verification reasons, rollout operators may log on to the respective computer before the end user receives the new machine and is able to activate the Power-on Authentication. Thus, the scenario may be as follows: 1. SafeGuard Enterprise is installed on an endpoint computer. 2. After rebooting the computer, the rollout operator logs on. 3. The rollout operator is added to the POA and the POA becomes active. The rollout operator becomes owner of the computer. Upon receiving the computer the end user will not be able to log on to the POA and needs to perform a Challenge/Response procedure. To prevent that administrative operations on a SafeGuard Enterprise protected computer lead to an activation of the Power-on Authentication and the addition of rollout operators as users and machine owners to the computer, SafeGuard Enterprise offers the possibility of creating service account lists for SafeGuard Enterprise protected computers. The users included in these lists are thereby treated as SafeGuard Enterprise guest users. With service accounts the scenario is as follows: 1. SafeGuard Enterpriseis installed on an endpoint computer. 2. After rebooting the computer, a rollout operator included on a service account list logs on (Windows logon). 3. According to the service account list applied to the computer the user is identified as a service account and will be treated as a guest user. The rollout operator will not be added to the POA and the POA will not become active. The rollout operator will not become owner of the computer. The end user can log on and activate the POA. Note: As the service account list functionality is especially helpful during the rollout phase of an implementation, it is recommended to assign service account lists as early as in the first SafeGuard Enterprise configuration package created in the SafeGuard Management Center for configuring the SafeGuard Enterprise protected endpoint computer after installation. 85 SafeGuard® Enterprise 5.50, Administrator help 13.1 Creating service account lists and adding users To create service account lists and add users, do as follows: 1. Click Policies in the navigation area. 2. Select Service account lists in the policy navigation window. 3. In the context menu of Service account lists, click New > Service account list. 4. Enter a name for the service account list and click OK. 5. Select the new list under Service account lists in the policy navigation window. 6. Right-click in the action area to open the context menu for the service account list. In the context menu, select Add. 7. A new user line is added. Enter the User Name and the Domain Name in the respective columns and press Enter. To add further users, repeat this step. 8. Save your changes by clicking the Save icon in the toolbar. The service account list is now registered and can be selected for assignment when creating a policy. 13.2 Additional information for entering user and domain names There are different methods for specifying users in service account lists using the two fields User Name and Domain Name (see Covering different combinations for logging on, page 86). Furthermore, certain restrictions apply for valid input in these fields (see Restrictions, page 88). 13.2.1 Covering different combinations for logging on The two separate fields User Name and Domain Name per list entry offer the flexibility to cover all available combinations for logging on, for example "user@domain" or "domain\user". To handle several user name/domain name combinations, you can use asterisks (*) as wild cards. An asterisk is allowed as the first sign, the last sign and the only sign. 86 SafeGuard® Enterprise 5.50, Administrator help For example: User Name: Administrator Domain Name: * This combination specifies all users with the user name "Administrator" who log on to any network or local machine. The predefined domain name [LOCALHOST] available in the drop-down list of the Domain Name field stands for the logon on any local workstation. For example: User Name: "*admin" Domain Name: [LOCALHOST] This combination specifies all users whose user names end on "admin" and who log on to any local machine. Furthermore, users may log on in different ways, e.g.: user: test, domain: mycompany or user: test, domain: mycompany.com. As domain specifications in the service account lists are not automatically resolved, there are three possible methods for specifying the domain correctly: You know exactly how the user is going to log on and enter the domain accordingly. You create several service account list entries. You use wild cards to cover all different cases (user: test, domain: mycompany*). Note: To avoid any problems caused by the fact that Windows may not use the same character sequence, but truncate names, it is recommended to enter the FullQualifiedName and the NetBIOS name or use wildcards. 87 SafeGuard® Enterprise 5.50, Administrator help 13.2.2 Restrictions Asterisks are only allowed as the first sign, the last sign and the only sign. Following are examples for valid and invalid strings using asterisks: Valid strings are for example admin*, *, *strator, *minis*. Invalid strings are for example **, Admin*trator, Ad*minst*. Furthermore the following restrictions apply: The character ? is not allowed in user logon names. The characters / \ [ ] : ; | = , + * ? < > " are not allowed in domain names. 13.3 Editing and deleting service account lists As a security officer with the right Modify service account lists you can edit or delete service account lists at any time: To edit a service account list, double-click it in the policy navigation window. The service account list is opened and you can add, delete or modify user names on the list. To delete a service account list, select it in the policy navigation window, open the context menu and select Delete. 13.4 Assigning a service account list via policy To select and assign a service account list, do as follows: 1. Create a new policy of the type Authentication or select an existing one. 2. Under Logon Options, select the required service account list from the drop-down list of the Service Account List field. Note: The default setting of this field is [No list], i.e. no service account list applies. Rollout operators logging on to the computer after installation of SafeGuard Enterprise will therefore not be treated as guest users and may activate Power-on Authentication and be added to the computer. To undo the assignment of a service account list, select the [No list] option. 3. Save your changes by clicking the Save icon in the toolbar. You can now transfer the policy to the respective computers to make the service accounts available on the computer. 88 SafeGuard® Enterprise 5.50, Administrator help Note: If you select different service account lists in different policies which are all relevant according to the RSOP (Resulting Set of Policies, the settings valid for a specific computer/group), the service account list assigned in the last policy applied will overrule all previously assigned service account lists. Service account lists will not be merged. 13.5 Transferring the policy to the endpoint computer The service account list functionality is especially helpful and important during initial installation in the rollout phase of an implementation. It is therefore recommended to transfer the service account settings to the endpoint computer immediately after installation. To make the service account list available on the endpoint computer at this point, include a policy of the type Authentication when you create the initial configuration package for configuring the endpoint computer after installation. You can change the service account list settings at any time and the changes will be transferred to the endpoint computer via the server in the usual way. 13.6 Logging on to an endpoint computer using a service account At the first Windows logon after rebooting the computer, a user included on a service account list logs on to the respective machine as a SafeGuard Enterprise guest user. This first Windows logon to the machine neither kicks off a pending Power-on Authentication nor adds the user to the computer. The SafeGuard Enterprise System Tray icon balloon tool tip "Initial user synchronisation completed" will not be displayed. 13.6.1 Service account status display on the endpoint computer In addition, the guest user logon status is also available via the System Tray Icon.

SafeGuard® Enterprise 5.50, Administrator help 15.1 General settings Policy setting Explanation LOADING OF SETTINGS Policy Loopback Replay Machine Settings If “Replay Machine Settings” is selected for a policy in the field Policy Loopback, and the policy originates from a machine (“Replay Machine“ setting of a user policy does not have any effect), this policy is implemented again at the end. This then overrides any user settings and the machine settings apply. Ignore User If you select “Ignore User” for a policy (machine policy) in the field Policy Loopback and the policy originates from a machine, only the machine settings are analyzed. User settings are not analyzed. No Loopback No loopback is the standard behavior in which user policies take priority over machine policies. How are settings “Ignore User” and “Replay Machine Settings” analyzed? If there are active policy assignments, the machine policies are analyzed and consolidated first. If consolidation of the various policies results in the “Ignore User” attribute in policy loopback, policies that would have been applied for the user are no longer analyzed. This means that the same policies apply to the user as to the machine. If “Replay Machine Settings” value is applied in the case of the policy loopback, once the individual machine policies have been consolidated, the user policies are then merged with the machine policies. After consolidation the machine policies are re-written and override any user policy settings. This means that if a setting is present in both policies, the machine policy value overrides the user policy value. If the consolidation of individual machine policies results in the standard value, the following applies: User settings take priority over machine settings. 98 SafeGuard® Enterprise 5.50, Administrator help Policy setting Explanation TRANSFER RATE Connection interval to server (min) Determines the period in minutes after which a SafeGuard Enterprise Client sends a policy (changes) enquiry to the SafeGuard Enterprise Server. Note: To prevent a large number of clients contacting the server at the same time, communication is always carried out in a period of +/- 50% of the set connection interval. Example: Setting “90 minutes” results in a communication period between the client and the server of 45 to 135 minutes. LOGGING Feedback after number of events The log system, implemented as Win32 Service “SGM LogPlayer”, collects log entries generated by SafeGuard Enterprise for the central database and stores them in local log files. These are located in the Local Cache in the “Auditing\SGMTransLog” directory. These files are transferred to the transport mechanism which then sends them to the database via the SGN Server. Transfer takes place as soon as the transport mechanism has succeeded in creating a connection to the server. The log file therefore increases in size until a connection has been established. To limit the size of each log file, it is possible to set a maximum number of log entries in the policy. Once the preset number of entries has been reached the logging system places the log file in the SGN Server transport queue and starts a new log file. CUSTOMIZATION Language used on client 99 Determines the language in which settings for SafeGuard Enterprise are displayed on the endpoint computer: Besides the supported languages, users may select the computer's operating system language setting.

It stores all keys, policies, user certificates and audit files. All data stored in the local cache are signed and cannot be changed manually. By default logon recovery is deactivated. i.e. the Windows Local Cache will be restored automatically from its backup. In this case, no Challenge/Response procedure is required for repairing the Windows Local Cache. If the Windows Local Cache is to be repaired explicitly via a Challenge/Response procedure, set this field to “YES“. Enable Local Self Help Enable Local Self Help Determines whether users are permitted to log on to their computers via Local Self Help if they have forgotten their password. Using Local Self Help the user can log on by answering a specified number of previously defined questions in the Power-on Authentication. Thus, in case of an emergency, the user can regain access to their computer even if neither telephone nor internet connection are available. A Challenge/Response procedure is not necessary in this case. Local Self Help helps reducing help desk efforts and cost. Notice: For the user to be able to use Local Self Help, automatic logon to Windows has to be enabled. Otherwise, Local Self Help will not work. Minimal length of answers In this field, define the minimum length (in characters) for the answers to be saved for Local Self Help on the endpoint computer. Welcome text under Windows In this field you can specify the individual information text to be displayed in the first dialog when launching the Local Self Help Wizard on the endpoint computer. Prior to specifying the text here, it has to be created and registered. Users can define their own questions As a security officer you can define the set of questions to be answered centrally and distribute it to the endpoint computer via the policy.

YES: User is permitted to generate a challenge. In this case, the user can regain access to their computer via a C/R procedure in case of emergencies. NO: User is not permitted to issue a challenge. In this case, the user cannot initiate a C/R procedure to regain access to their computer in case of an emergency. Allow automatic logon to Windows Allows the user to log on to Windows automatically after authentication via Challenge/Response. YES: User is automatically logged on to Windows. NO: Windows logon screen appears. Anwendungsfall: A user has forgotten their password. After the Challenge/Response procedure, SafeGuard Enterprise logs the user on at the computer without an SGN password. In this case automatic Windows logon is switched off and the Windows logon screen is displayed. The user cannot log on because they do not know the SGN password (= Windows password). “YES” allows automatic logon and the user is able to move on from the Windows logon screen. Information text Displays an information text when the Challenge button is pressed in the POA. Information texts can include, e.g. “Please contact Support Desk on telephone number 01234-56789.” Prior to specifying a text here, you must create it as a text file in the policy navigation area under Information text.

The POA does not offer the option to start the PC with a floppy disk or other external medium. NO: Users may start the PC from hard disk, floppy disk or external medium (USB, CD etc.) LOGON OPTIONS Logon mode Determines how a user needs to authenticate themselves at the POA. User ID/Password The user may not log on with a token. Logon must be via user name and password in the POA. Token The user can only log on to the POA using a token or smartcard. This process offers a higher level of security. The user is requested to insert the token at logon. User identity is verified by token ownership and PIN presentation. After the user has entered the correct PIN, SafeGuard Enterprise automatically reads the data for user logon. Notice: Once this logon process has been selected, users can only log on using a previously issued token. A combination of the above settings is allowed. To test whether logon using a token works, first select both settings. Only deselect logon mode User ID/ Password, if authentication using the token was successful. 103 SafeGuard® Enterprise 5.50, Administrator help Policy setting Explanation Logon options using token Fingerprint Select this setting to enable logon with Lenovo Fingerprint Reader Users to whom this policy applies can then log on with a fingerprint or a user name and password. This procedure provides the maximum level of security. When logging on, the user swipes his or her finger over the fingerprint reader. Upon successful recognition of the fingerprint, the Power-on Authentication process reads the user’s credentials and logs the user on to Poweron Authentication. The system then transfers the credentials to Windows, and the user is logged on to the computer. Notice: After selecting this logon procedure, the user can log on only with a pre-enrolled fingerprint or a user name and password. Token and fingerprint logon procedures cannot be combined on the same computer. Determines the type of token or smartcard to be used at the user PC. Non-cryptographic: Authentication at POA and Windows based on user credentials. Kerberos: Certificate-based authentication at POA and Windows. The SO issues a certificate in a PKI and stores it on the token. This certificate is imported as a user certificate into the SafeGuard Enterprise database. If an automatically generated certificate already exists in the database, it is replaced by the imported certificate. Hint: Challenge/Response is not possible with a token supporting Kerberos as no user credentials are provided in the POA that could be used for a Challenge/Response procedure. 104 SafeGuard® Enterprise 5.50, Administrator help Policy setting Explanation PIN used for autologon with token Specify a default PIN to enable the user to automatically log on at the Power-on Authentication using a token or smartcard. The user is requested to insert the token at logon and is then passed through the Power-on Authentication. Windows will be started. PIN rules do not need to be observed. Notice: This option is only available, if Token has been selected as Logon mode. If this option is activated, then Pass-through to Windows must be set to Disable passthrough to Windows. Display unsuccessful logons for this user Displays (setting: YES) after logon at POA and Windows a dialog showing information on the last failed logon (user name/date/time). Display last user logon Displays (setting: YES) after logon at POA and Windows a dialog showing information on the Disable “forced logoff” in workstation lock 105 last successful logon (user name/date/time) last user credentials of the logged on user If users wish to exit the endpoint computer for a short time only, they can click Block workstation to block the computer for other users and unlock it with the user password. If this option is set to NO, the user who has locked the computer as well as an administrator can unlock the it. If an administrator unlocks the computer, the currently logged on user is logged off automatically. Setting this field to YES changes this behavior. In this case, only the user can unlock the computer. The administrator cannot unlock it and the user will not be logged off automatically. Note: This setting only takes effect under Windows XP. SafeGuard® Enterprise 5.50, Administrator help Policy setting Explanation Activate user/domain preselection YES: The POA saves the user name and domain of the last logged on user. Users therefore do not need to enter their user names every time they log on. NO: The POA does not save the user name and the domain of the last logged on user. Pass through to Windows Note: For the user to be able to grant other users access to their computer, the user has to be permitted to deactivate logon passthrough to Windows. Service Account List Let user choose freely The user can decide by enabling/disabling this option in the POA logon dialog whether automatic logon at Windows is to be performed. Enforce pass-through to Windows The user will always be automatically logged on to Windows. Disable pass-through to Windows After the POA logon, the Windows logon dialog will be displayed. The user has to log on to Windows manually. To prevent that administrative operations on a SafeGuard Enterprise protected computer lead to an activation of the Power-on Authentication and the addition of rollout operators as users to the computer, SafeGuard Enterpriseoffers the possibility of creating service account lists for SafeGuard Enterprise endpoint computers. The users included in these lists are thereby treated as SafeGuard Enterprise guest users. Prior to selecting a list here you first have to create the lists in the Policies navigation are under Service Account Lists. 106 SafeGuard® Enterprise 5.50, Administrator help Policy setting Explanation BitLocker Options BitLocker Logon mode BitLocker Fallback Logon mode 107 You can select from the following options for the BitLocker logon mode. TPM: The key for logon is stored on the TPM chip. TPM + PIN: The key for logon is stored on the TPM chip and a PIN is also required for logon. Settings for the PIN are given under PIN and password. USB Memory Stick: The key for logon is stored on a USB stick. TPM + USB Memory Stick: The key for logon is stored on the TPM chip and on a USB stick. Logon can either be with the TPM chip or USB stick. In case logon fails, SafeGuard Enterprise offers logon with USB stick as a fallback mechanism or an error message output. Note: If you select USB Memory Stick as the logon mode, this option is not offered. SafeGuard® Enterprise 5.50, Administrator help Policy setting Explanation TPM platform validation profile If TPM can be found on the endpoint computer, it can be configured which type of TPM platform validation profile should be used. The TPM platform validation profile specifies the measurements that are used to protect BitLocker encryption keys. A platform validation profile consists of a set of Platform Configuration Register (PCR) indices. Microsoft recommends to use the default TPM platform validation profile in Windows Vista, which secures the following: the encryption key against changes to the Core Root of Trust of Measurement (CRTM), BIOS, and Platform Extensions (PCR 0) Option ROM Code (PCR 2) Master Boot Record (MBR) Code (PCR 4) NTFS Boot Sector (PCR 8) NTFS Boot Block (PCR 9) Boot Manager (PCR 10) BitLocker DE Access Control (PCR 11) Note: This option is only available if you select TPM as logon mode. If USB Memory Stick is the selected logon mode, this option is not offered. For further information on the TPM validation profile follow this link: http://msdn2.microsoft.com/en-us/library/ aa376469.aspx FAILED LOGONS Maximum no. of failed logons Determines how many times a user can attempt to log on using an invalid user name or password.

However, when issuing a new PIN, do not use any character with the combination ALT + < character > as this input mode is not available at Power-on Authentication. Rules for PINs used to log on to the system are defined in policies of the type PIN. Note: If password rules have been defined in the SafeGuard Management Center, no rules should be defined in Active Directory. Policy setting Explanation RULES 111 Min. PIN length Displays how many characters a PIN must comprise when changed by the user. The required value can be entered directly or increased/reduced using the arrow keys. Max. PIN length Displays the maximum number of characters a PIN must comprise when changed by the user. The required value can be entered directly or increased/reduced using the arrow keys. Min. number of letters Min. number of digits Min. number of special characters This setting specifies that a PIN may not consist exclusively of letters, numbers or special characters, but must consist of a combination of at least two (e.g. 15flower etc). This setting is only practical, if a minimum PIN length of greater than 2 has been defined. Case sensitive This setting is only effective with Use forbidden PIN list and User name as PIN forbidden. Case 1: You have entered “board” in the list of forbidden PINs. If the Case sensitive option is set to YES, additional password variants such as BOARD, BoaRD will not be accepted and logon will be denied. Case 2: “EMaier” is entered as a user name. If option Case sensitive is set to YES and option User name as PIN forbidden is set to NO, user EMaier cannot use any variant of this user name (e.g. “emaier“ or “eMaiER“) as a PIN. Keyboard row forbidden Consecutive key sequences include e.g. “123” or “qwe”. A maximum of two adjacent characters on the keyboard is allowed.

SafeGuard® Enterprise 5.50, Administrator help Policy setting Explanation Keyboard column forbidden Refers to keys arranged consecutively in columns on the keyboard such as “yaq1”, “xsw2” or “3edc” (but not “yse4”, “xdr5” or “cft6”!). A maximum of two adjacent symbols in a single keyboard column is permitted. If you disallow keypad columns, combinations like these are rejected as PINs. Consecutive key sequences relate only to the alphanumerical keyboard area. 3 or more consecutive characters forbidden Activation of this option disallows key sequences which are consecutive series of ASCII code symbols in both ascending and descending order (“abc”; “cba”; “;<” etc.). which consist of three or more identical symbols (“aaa” or “111”). User name as PIN forbidden Determines whether user name and PIN may be identical. YES: Users may use their Windows user names as PINs. NO: Windows user name and PIN must be different. Use forbidden PIN list Determines whether certain character sequences must not be used for PINs. The character sequences are stored in the list of forbidden PINs (e.g. .txt file). List of forbidden PINs Defines character sequences which must not be used for PINs. If a user uses a forbidden PIN, an error message will be displayed.

This setting prevents the user from changing a password too many times within a specific period. Example: User Miller defines a new PIN (e.g. “13jk56”). The minimum change interval for this user (or group to which this user is assigned) is set to five days. After two days the user wants to change the PIN to “13jk56”. The PIN change is rejected because Mrs. Miller may only define a new password after five days have passed. PIN change after max. (days) If the maximum period of validity is activated, the user has to define a new PIN after the set period has expired. Notify of forced change before (days) A warning message is displayed “n” days before PIN expiry reminding the user to change their PIN in “n” days. Alternatively, the user may change the PIN immediately. GENERAL PIN history length 113 Determines when previously used PINs can be reused. It makes sense to define the history length in conjunction with the PIN change after max. (days) setting. Example: The PIN history length for user Miller is set to 4, and the number of days after which the user must change their PIN is 30. Mr. Miller is currently logging on using the PIN “Informatics”. After the 30 day period expires, he is asked to change his PIN. Mr. Miller types in “Informatics” as the new PIN and receives an error message that this PIN has already been used and he needs to select a new PIN.

Password synchronization will only be performed after logging on using the old password first. Fast (wait for machine to connect) If a user changes their password on a SafeGuard Enterprise endpoint computer, password synchronization with other computers, on which the user is also registered, will be performed as soon as the other computer has established a connection to the server.

SafeGuard® Enterprise 5.50, Administrator help 15.8 Device Protection The core of SafeGuard Enterprise is the encryption of data on different data storage devices. Encryption can be volume or file based with different keys and algorithms. Policies of the type Device Protection also include settings for SafeGuard Data Exchange and SafeGuard Portable. For further details on SafeGuard Data Exchange and SafeGuard Portable refer to the SafeGuard Enterprise User help. Policy setting Explanation Media encryption mode Used to protect devices (PCs, Notebooks and PDAs) and all types of removable media. The primary objective is to encrypt all data stored on local or external storage devices. The transparent operating method enables users to continue to use their usual applications e.g. Microsoft Office as usual. Transparent encryption means that all encrypted data (whether in encrypted directories or volumes) is automatically decrypted in the main memory as soon as it is opened in a program. A file is automatically re-encrypted when it is saved. The following options are available: No Encryption Volume based (= transparent, sector based encryption) Ensures that all data is encrypted (incl. boot files, swapfiles, idle files/hibernation files, temporary files, directory information etc.) without the user having to change normal operating procedures or consider security. Note: If an encryption policy exists for a volume or a volume type and encryption of the volume fails, the user is not allowed to access it. Windows 7 System Partition: Note that for Windows 7 Professional, Enterprise and Ultimate, a system partition is created on endpoint computers without a drive letter assigned. This system partition cannot be encrypted by SafeGuard Enterprise. Access to Unidentified File System Objects: Unidentified File System Objects are volumes that cannot be clearly identified as plain or device-encrypted by SafeGuard Enterprise. If an encryption policy exists for an Unidentified File System Object, access to this volume will be denied. If no encryption policy exists, the user can access the volume. 122 SafeGuard® Enterprise 5.50, Administrator help Policy setting Explanation Note: If an encryption policy with Key to be used for encryption set to an option that enables key selection (e.g., Any key in user key ring) exists for an Unidentified File System Object volume, there is a period of time between the key selection dialog being displayed and access being denied. During this time period the volume can be accessed. As long as the key selection dialog is not confirmed, the volume is accessible. To avoid this, specify a preselected key for encryption (see description of policy setting Key to be used for encryption). Furthermore, this period of time also occurs for Unidentified File System Object volumes connected to an endpoint computer, if the user has already opened files on the volume when an encryption policy takes effect. In this case, it cannot be guaranteed that access to the volume will be denied as this could lead to data loss. Volumes with enabled Autorun functionality: If Autorun is enabled for a volume for which an encryption policy exists, the following problems can occur: The volume is not encrypted. If the volume is a UFO, access is not denied. Access to BitLocker To Go encrypted volumes: If SafeGuard Enterprise is used with BitLocker To Go support enabled and a SafeGuard Enterprise encryption policy exists for a BitLocker To Go encrypted volume, access to the volume will be denied. If no SafeGuard Enterprise encryption policy exists, the user can access the volume. Note: If the Autorun settings for a BitLocker To Go encrypted USB stick are set to the default values, it can occur that access will not be denied although a SafeGuard Enterprise encryption policy exists. This only occurs under Windows Vista. 123 SafeGuard® Enterprise 5.50, Administrator help Policy setting Explanation For further information on BitLocker To Go, see SafeGuard Enterprise and BitLocker To Go on page 278. File based (= transparent, file based encryption (Smart Media Encryption)) Ensures that all data is encrypted (apart from Boot Medium and directory information) with the benefit that even optical media such as CD/DVD can be encrypted or data can be swapped with external computers on which SafeGuard is not installed (provided policies permit). Note: Data encrypted u.sing “File based encryption” cannot be compressed. Nor can compressed data be file based encrypted. Boot volumes will never be file-based encrypted. They will be automatically exempt from file-based encryption, even if a corresponding rule is defined. GENERAL SETTINGS Algorithm to be used for encryption Sets the encryption algorithm.

The following options are available: Any key in user key ring All keys from a user's key ring are displayed and the user can select any one of them. Note: This option has to be selected, if you define a policy for file based encryption for an unmanaged endpoint computer protected by SafeGuard Enterprise (standalone). Any key in user key ring except user key All except user keys from a user's key ring are displayed and the user can select any one of them. Any group key in user key ring All group keys from a user's key ring are displayed and the user can select any one of them. Defined machine key: The machine key is used - the user CANNOT select a key Notice: This option has to be selected, if you define a policy for volume based encryption for a unmanaged endpoint computer protected by SafeGuard Enterprise (standalone mode). If you nevertheless select Any key in user key ring and the user selects a locally created key for volume based encryption, access to this volume will be denied. Any key in key ring, except locally created keys All except locally generated keys from a key ring are displayed and the user can select any one of them. Defined key on list The administrator can select any available key when setting policies in the Management Center. SafeGuard® Enterprise 5.50, Administrator help Policy setting Explanation The key has to be selected under Defined key for encryption. Notice: If option Defined machine key is used If SafeGuard Enterprise Device Encryption is not installed on a endpoint computer (no POA, no volume based encryption), a policy defining the Defined machine key as the key to be used for file based encryption will not become effective on this computer. The defined machine key is not available on a computer of this type. The data cannot be encrypted. Policies for unmanaged endpoint computers protected by SafeGuard Enterprise (standalone): Note that only option Any key in user key ring can be used when creating policies for unmanaged endpoint computers. In addition, creating local keys must be allowed for this type of endpoint computer. In case the media passphrase feature is activated for unmanaged endpoint computers, the Media Encryption Key is automatically used as Defined key for encryption, since no group keys are available on unmanaged endpoint computers. Selecting another key under Defined key for encryption when creating a removable media policy for unmanaged endpoint computers will have no effect. 126 SafeGuard® Enterprise 5.50, Administrator help Policy setting Explanation Defined key for encryption This field becomes only active, if you have selected option Defined key on list in the Key to be used for encryption field.

In case a policy of Type Device protection with target: Removable Media this key is used to encrypt the Media Encryption Key when the media passphrase functionality is enabled (User may define a passphrase for a device: Yes) For Device Protection policies for removable media the settings Key to be used for encryption Defined key for encryption therefore have to be specified independently from each other. Policies for unmanaged endpoint computers protected by SafeGuard Enterprise (standalone): In case the media passphrase feature is activated for unmanaged endpoint computers, the Media Encryption Key automatically is used as Defined key for encryption automatically, since no group keys are available on unmanaged endpoint computers. User is allowed to create a local key This setting determines whether the user can generate a local key on their computer or not. Local keys are generated on the endpoint computer based on a passphrase entered by the user. The passphrase requirements can be set in policies of the type Passphrase. These keys are also saved in the database. The user can use them on any computer they are logged on to. Local keys can be used for secure data exchange via SafeGuard Data Exchange (SG DX). VOLUME-BASED SETTINGS Users may add or remove keys to or from encrypted volume 127 YES: Endpoint computer users may add/remove keys to/ from a key ring. The dialog is displayed via the context menu command Encryption / Encryption tab. NO: Endpoint computer users may not add additional keys SafeGuard® Enterprise 5.50, Administrator help Policy setting Explanation Reaction to unencrypted volumes Defines how SafeGuard Enterprise handles unencrypted media: The following options are available: Reject (= text medium is not encrypted) Accept only blank media and encrypt Accept all media and encrypt User may decrypt volume Allows the user to decrypt the volume via a context menu command in Windows Explorer. Fast initial encryption Select this setting to enable the fast initial encryption mode for volume-based encryption. This mode reduces the time needed for initial encryption on endpoint computers. Note: This mode may lead to a less secure state. For further information, see Fast initial encryption on page 55. Proceed on bad sectors Specifies whether encryption should proceed or be stopped in case bad sectors are detected. The default setting is YES. FILE BASED SETTINGS Initial encryption of all files Automatically starts initial encryption for a volume after user logon. The user may need to select a key from the key ring beforehand. User may cancel initial encryption Enables a user to cancel initial encryption. User is allowed to access unencrypted files Defines whether a user may access unencrypted data on a volume. User may decrypt files Enables a user to decrypt individual files or whole directories (via the Windows Explorer extension <rightclick>). User may define a Media Passphrase for devices Enables a user to define a media passphrase on his computer. The media passphrase allows to easily access all used local keys on computers without SafeGuard Data Exchange via SafeGuard Portable. 128 SafeGuard® Enterprise 5.50, Administrator help 129 Policy setting Explanation Unhandled Applications Allows other applications to be defined which are to be ignored by the SafeGuard Enterprise filter driver and thereby excluded from transparent encryption/decryption. The delimiter to be used for these applications is ’;’. One example of an unhandled application is a backup program. To ensure that data is not decrypted when creating a backup, this application can be exempted from encryption/decryption. The data is backed up in encrypted form. Note: Since these are machine-specific settings, they are not applied until the endpoint computer is rebooted. Defining unhandled applications Typical use: Backup programs can be defined as exempted so they will always be able to read and back up encrypted data. Applications which might trigger malfunctions when used alongside SafeGuard Enterprise, but do not require encryption, can generally be exempted from encryption. The full name of the executable file (optionally including path information) is used to specify an exempted application. Note: Unhandled applications can only be defined for local storage devices. For a global policy of the type Device Protection, target Local Storage Devices must be selected. For all other targets, option Unhandled Applications is not available. Removable media only Copy SG Portable to Removable Media If this option is switched on, SafeGuard Portable is copied to any removable media connected to the endpoint computer. SafeGuard Portable enables the exchange of encrypted data with removable media without the recipient having SafeGuard Enterprise installed. The recipient can decrypt and re-encrypt the encrypted files using SafeGuard Portable and the corresponding passphrase. The recipient can re-encrypt files with SafeGuard Portable or use the original key for encryption. SafeGuard Portable does not have to be installed or copied to the recipient's computer but can be used directly from the removable media. SafeGuard® Enterprise 5.50, Administrator help Policy setting Explanation Default initial encryption key This field offers a dialog for selecting a key which is used for file based initial encryption. If you select a key here, the user cannot select a key when initial encryption starts. Initial encryption starts without user interaction. The key selected will always be used for initial encryption. Example: Prerequisite: A default key for initial encryption has been set. When the user connects a USB device to the computer, initial encryption automatically starts. The key defined is used. The user does not have to interfere. If the user afterwards wants to re-encrypt files or save new files on the USB device, he can select any key (if allowed and available). If the user connects a different USB device, the key defined for initial encryption will be used again. This key will also be used for all encryption processes that follow until the user explicitly selects a different key. Note: In case the media passphrase feature has been activated, this option is deactivated. The Defined key for encryption will be used. Plaintext folder The folder specified here will be created on every removable media. Files that are copied to this folder will always stay plain. 130 SafeGuard® Enterprise 5.50, Administrator help 15.9 Specific machine settings - basic settings Policy setting Explanation POWER-ON AUTHENTICATION (POA) 131 Enable Power-on Authentication Defines whether the POA is permanently switched on or off. Note: For security reasons we strongly recommend to keep the POA switched on. Deactivating the POA reduces the system security to Windows logon security and increases the risk of unauthorized access to encrypted data. Forbid guest user Defines whether a user is entitled to log on to Windows. Access denied if no connection to the server (days) (0 = no check) Refuses POA logon if the PC has not been connected to the server for longer than a set period. Only assigned user may log on Defines whether a user is entitled to log on to Windows. YES: Only users recognized in POA can log on. NO: Users not recognized in POA can log on. Import of new users allowed for Determines whether another user can be added to the POA. Differentiates between simply machine owners or any user present in the POA. Secure Wake On LAN (WOL) The “Secure Wake On LAN” policy enables the endpoint computer to prepare for software rollouts in which the necessary parameters such as temporary deactivation of POA and a time interval for Wake On LAN can be imported directly into and analyzed by the endpoint computer. The rollout team can design a scheduling script using the commands provided to guarantee maximum endpoint computer protection despite deactivated POA. Please be advised that deactivating the POA - even for a limited number of boot processes - reduces the level of security for your system! EXAMPLE: The SW rollout team notifies SafeGuard Enterprise SO about a planned software rollout for the 25th September 2010 between 03:00 and 06:00 am. 2 reboots are required. The local software rollout agent must be able to log on to Windows. SafeGuard® Enterprise 5.50, Administrator help Policy setting Explanation The SO creates the following policy and assigns it to the corresponding endpoint computers: Number of auto logons (0 = no WOL): 5 Windows logon permitted during WOL: Yes Start of time slot for external WOL Start: 24th Sept. 2010, 12:00 End of time slot for external WOL Start: 25th Sept. 2010, 06:00 The SO provides a buffer of 3 for automatic logons. The security officer sets the time interval to 12 o'clock midday on the day before the software rollout to allow the scheduling script SGMCMDIntn.exe to be started promptly and WOL starts no later than the 25th September at 3:00 am. The software rollout team produces two commands for the scheduling script: - Starting 24th Sept.2010, 12:15 am, SGMCMDIntn.exe / WOLstart - Starting 26th Sept.2010, 09.00 am SGMCMDIntn.exe / WOLstop The software rollout script is dated 25.09.2010, 03:00. WOL can be explicitly deactivated again at the end of the script using SGMCMDIntn.exe /WOLstop. All endpoint computers logging in before the 24th of September 2010 and which connect to the rollout servers will receive the new policy and the scheduling commands. Any endpoint computer on which the schedule triggers the command SGMCMDIntn/WOLstart between 24th Sept. 2010, 12:00 midday and 25th Sept. 2010, 06:00 am falls within the WOL time interval and therefore Wake On LAN will be activated. 132 SafeGuard® Enterprise 5.50, Administrator help Policy setting Explanation Number of auto logons Defines the number of reboots while Power-on Authentication is switched off for Wake On LAN. This setting temporarily overwrites the Enable Power On Authentication setting until the automatic logons reach the preset number. Power-on Authentication is then reactivated. Example: the number of automatic logons is set to 2; “Enable Power-on Authentication” is switched on. The PC boots twice without authentication via POA. For Wake On LAN, we always recommend allowing three more reboots than necessary to overcome any unforeseen problems. Windows logon allowed during WOL Determines whether Windows logon is permitted during Wake On LAN, e.g. for a software update. This setting is interpreted by the POA. Start of time slot for external WOL start End of time slot for external WOL start Date and time can be either selected or input for the start and end of the Wake On LAN (WOL). Date format: MM/DD/YYYY Time format: HH:MM The following input combinations are possible: Defined start and end of WOL. End of WOL is defined, start is open. No entries: no time interval has been set. In the event of a planned software rollout, the SO should set the timeframe for the WOL such that the scheduling script can be started early enough to allow all endpoint computers sufficient time for booting. WOLstart: The starting point for the WOL in the scheduling script must be within the time interval set in the policy. If no interval is defined, WOL is not locally activated on the SafeGuard Enterprise protected endpoint computer. WOLstop: This command is carried out irrespective of the final point set for the WOL. Note: From version 5.20 a WOL setting will only take effect, if a time interval has been defined. In case of a version update this also means that WOL policies defined in version 5.10 will at first no longer be effective. After migration the security officer will have to define a timeframe for these policies in addition. 133 SafeGuard® Enterprise 5.50, Administrator help Policy setting Explanation DISPLAY OPTIONS Display machine identification Displays either the computer name or a defined text in the POA title bar.

SafeGuard® Enterprise 5.50, Administrator help 16 SafeGuard Configuration Protection Enterprise networks are currently characterized by a proliferation of easily accessible computer ports, such as USB, FireWire and PCMCIA. In addition, a variety of communication adapters (such as Bluetooth, IrDA, and WLAN) and device types (such as storage devices, printers, digital cameras, smart phones, and PDAs) all enable effortless access to endpoints using these ports and devices. These devices enable optimal accessibility and productivity, but they leave endpoints wide open to infiltration. With the amount of corporate data residing on endpoints estimated at over 60%, endpoints may be the most valuable, and vulnerable, part of the enterprise network. Today, enterprise IT is focusing on the tradeoffs between productivity and security. Enterprises' need for productivity attracts them to innovative devices and security concepts. But they are severely challenged to maintain the ultimate precautionary measures against leakage, theft, fraud, virus invasion, eavesdropping and the general misuse of information and resources. According to Vista research, 70% of IT security breaches originate from within the enterprise. Thus, enterprises today are making internal security, especially internal access to network resources, their highest priority, even above gateway solutions like antivirus and firewalls. Today's greatest enterprise security challenge is providing access to key information without exposing it to risk and trusting internal users while retaining enough control over their actions to verify their reliability. True protection can only be obtained by establishing a "digital wall" around each computer and by intelligently protecting its ports, while judiciously allowing access of approved devices. 138 SafeGuard® Enterprise 5.50, Administrator help 16.1 The SafeGuard Configuration Protection solution Together with SafeGuard PortAuditor (see the SafeGuard PortAuditor User Guide), SafeGuard Configuration Protection provides a comprehensive solution which enables organizations to see what ports and devices are being used in their organization (visibility), to define a policy that controls their usage and to protect data in motion. SafeGuard Configuration Protection controls every endpoint and every device, over every network or interface. It monitors real-time traffic and applies customized, highly-granular security policies over all physical, wireless and storage device interfaces, including: 1. Physical interfaces: a) USB b) FireWire c) PCMCIA d) Secure Digital (SD) e) Parallel f) Serial g) Modem 2. Wireless: a) WLAN b) Bluetooth c) InfraRed (IrDA) 3. Storage: a) Removable Storage Devices b) External Hard Drives c) CD/DVD Drives d) Floppy Drives e) Tape Drives 139 SafeGuard® Enterprise 5.50, Administrator help SafeGuard Configuration Protection detects and allows restriction of devices by device type, model, or even specific device serial number. For storage devices, SafeGuard Configuration Protection allows a security officer to block all storage devices completely. WLAN controls are based on MAC address, SSID, or network security level. 16.1.1 Features 1. Port Control – SafeGuard Configuration Protection can intelligently allow, block, or restrict the usage of any or all computer ports in your organization according to the computer on which they are located, the user who is logged in and/or the type of port. SafeGuard Configuration Protection controls: USB, PCMCIA, FireWire, Secure Digital, Serial, Parallel, Modem (e.g. dialup, 3G etc.), WLAN, IrDA, and Bluetooth ports. 2. Device Control – Highly granular identification and approval of devices, including a comprehensive list of device types and robust white listing of device models and even distinct devices (by serial number). 3. Storage Control – Special control over external and internal storage devices including Removable Media, External Hard Drives, CD/DVD, Floppy and Tape drives. Policy can block usage of device types, models, and even distinct devices (by serial number). 4. Block Hybrid Network Bridging - SafeGuard Configuration Protection allows security officers to control and prevent simultaneous use of various networking protocols that can lead to inadvertent or intentional hybrid network bridging (such as WLAN bridging and 3G card bridging). Configuring SafeGuard Configuration Protection Clients to block access to WLAN, Bluetooth, Modems, or IrDA links while the main wired TCP/IP network interface is connected to a network enables users to employ the various networking protocols only when they are disconnected from the network - avoiding the creation and potential abuse of a hybrid network bridge. Note: Internal ports such as storage busses such as IDE, SCSI, ATA and S-ATA, which are used to connect internal hard disk drives as well as PCI and PCI-X are allowed by default. 5. Block USB and PS/2 Hardware Key-Loggers - Blocking USB hardware key loggers which can tap and record every keystroke in your endpoints as well as render PS/2 hardware key loggers useless. 6. End User Messages – Whenever SafeGuard Configuration Protection Client enforces policies on an endpoint computer, a message is provided to the user in order to notify him or her on blocked ports or devices. 140 SafeGuard® Enterprise 5.50, Administrator help 16.2 Protection by SafeGuard Configuration Protection SafeGuard Configuration Protection protects your endpoints as follows: 16.2.1 Port control SafeGuard Configuration Protection can intelligently allow, block, or restrict the usage of any or all computer ports in your organization according to the computer on which they are located, the user who is logged in and/or the type of port. SafeGuard Configuration Protection controls: USB, PCMCIA, FireWire, Secure Digital, Serial, Parallel, Modem (e.g. dialup, 3G etc.), WLAN, IrDA and Bluetooth ports. A blocked port is unavailable, as if its wires were cut. An indication that a port is blocked is given when the computer boots or when a policy is applied that disables a previously allowed port. 16.2.2 Device control In addition to controlling port access, SafeGuard Configuration Protection provides another level of granularity by enabling you to define which devices can access a port. For USB, PCMCIA, and FireWire ports you can define which device types, device models and/or distinct devices can access a port, as follows: 141 Devices Types: This option enables you to restrict access to a port according to the type of device that is connected to it. Examples of device types are printing devices, network adapters, human interface devices (such as a mouse) or imaging devices. The device types that are available for selection are built into SafeGuard Configuration Protection. If you would like to allow a device that is not of one of the types listed here, you can use the Models or the Distinct Devices option, described below. Models: This option refers to the model of a specific device type, such as all HP printers or all M-Systems USB Memory Sticks. Distinct Devices: This option refers to a list of distinct devices each with their own unique serial number, meaning each is an actual specific device. For example: the CEO's PDA may be allowed and all other PDAs may be blocked. SafeGuard® Enterprise 5.50, Administrator help Protection against Hardware Key Loggers Hardware Key Loggers are devices that can be placed by a hostile entity between a keyboard and its host computer in order to tap and record keyboard input and steal vital information, especially identity and password. With SafeGuard Configuration Protection you can immunize your users against this threat: SafeGuard Configuration Protection can detect hardware key loggers connected to a USB or PS/2 port, and your policy can specify whether hardware key loggers should be blocked when detected. 16.2.3 Storage control Storage control provides an additional level of detail in which to specify the security requirements of your organization. This can apply to all storage devices, internal or external, fixed or detachable. You can block storage devices completely. Similarly to non-storage devices, described in the previous section, storage devices can be also approved according to their type, model, or distinct ID. Autorun control With SafeGuard Configuration Protection, you can let your end-users use their new sophisticated storage devices, while ensuring your endpoints are not exposed to potential exploits and risky applications these devices may carry. You can easily block auto-launch activities as part of your security policy. Using our unique granular Client technology, you can still allow smart storage devices to be used and block only their auto-run functionality which may be unsafe. 16.2.4 WLAN control WLAN control ensures that users only connect to approved networks. You can specify which networks or ad hoc links are allowed access. You can specify the MAC address of the access points, SSID of the network, authentication method and encryption methods to define approved links. 142 SafeGuard® Enterprise 5.50, Administrator help 16.2.5 SafeGuard PortAuditor Although not an integral part of SafeGuard Configuration Protection, SafeGuard PortAuditor is a tool that goes hand in hand with SafeGuard Configuration Protection and completes it by providing you with a full view of what ports, devices and networks are (or were previously) in use by your organization's users. You use the output of a SafeGuard PortAuditor scan to select the devices and networks whose usage you want to approve. More detail is provided in the SafeGuard PortAuditor User Guide. 16.3 Configuration protection policies A configuration protection policy specifies which ports are allowed, blocked, or restricted. Restricted means that only specified device types, device models, distinct devices, or WLAN connections can gain access through this port. A policy specifies the access permissions of storage device types, storage device models, and distinct storage devices, as well as WLAN connections, enabling you to specify whether they are allowed, blocked, or restricted (in the same manner as for devices). A policy can also block Hardware Key Loggers that are connected to a USB or a PS/2 port. 143 SafeGuard® Enterprise 5.50, Administrator help Hardware Key Loggers are devices that can be placed by a hostile entity between a keyboard and its host computer in order to log keyboard input. Your policy can specify whether hardware key loggers should be blocked when detected by SafeGuard Configuration Protection. SafeGuard Configuration Protection takes a positive security approach, meaning all devices are allowed unless you define a policy blocking their access. In the sections that follow we describe how to define a policy. 16.3.1 Defining configuration protection policies: workflow The following is an overview of the workflow for defining a new policy. A reference is provided from each of these steps to a sub-section that describes it in detail. The workflow suggests a simple and straightforward order for performing these steps, from which you can deviate, if you prefer. Step 1: Scan computers and detect port/device/WLAN usage: use SafeGuard PortAuditor to scan the computers in your network in order to detect the devices and WLAN networks that are currently connected and those that were previously connected (specified in their computer's registry), as described in the SafeGuard PortAuditor User Guide. You will use this information when defining a policy in order to easily specify which ports and devices are allowed, blocked, or restricted. Step 2: Plan your policy describes the information that you should gather in order to properly plan the best endpoint protection policy for your organization. Step 3: Create a policy describes how to create a new policy. You can create as many policies as needed, one for your entire organization or a different one for each group of computers or users. Step 4: Define port control describes how to define the port control aspect of your policy, meaning which ports are allowed, which are blocked and which are restricted to be used only by certain devices. In addition, this section describes how to prevent hybrid network bridging. Step 5: Define device control describes how to define more specifically which devices are allowed to connect through the restricted ports on your endpoints. Step 6: Define storage control describes how to define more specifically which storage devices are allowed to connect to your endpoints. Step 7: Define WLAN control describes how to define which WLAN connections are approved. Step 8: Define file control describes how to define the permissions for file types transferred from and to storage devices. 144 SafeGuard® Enterprise 5.50, Administrator help Step 9: Save and publish the policy describes the options for saving the policy in the policy database and publishing it so it can be associated to the relevant endpoint computers. 16.3.2 Step 1: Scan computers and detect port/device/WLAN usage Although not an integral part of SafeGuard Configuration Protection, SafeGuard PortAuditor is a tool that goes hand in hand with SafeGuard Configuration Protection and completes it by providing you with a full view of what ports, devices and networks are (or were previously) in use by your organization's users. You use the output of a SafeGuard PortAuditor scan to select the devices and networks whose usage you want to approve. 145 SafeGuard® Enterprise 5.50, Administrator help 16.3.3 Step 2: Plan your policy Before you start defining your policy, you should take the time to plan the policy best suited to your organization. The best SafeGuard Configuration Protection policy for your organization is one that meets its security needs while still fulfilling the requirements of the people who need access through the ports your organization's computers. The first thing to plan for is the types of OU (Organizational Units) and groups to which the policies will apply. User and computer policies By default, SafeGuard Configuration Protection uses User Group and Computer Group definitions that are controlled by Active Directory. Each option has its own benefits, as described below. Per user groups: Defining your policies per user groups enables you to be specific regarding the permissions for each user. Policies that apply to users override policies that apply to computers. If you decide to manage your organization by assigning policies to user groups, we recommend that you still define one or more general policies for computers. This enables the protection of each computer port even when no user is logged in. Using the combination of user policies and computer policies means that, for example, you can block USB storage devices on all the Customer Service department's computers, but you can allow the manager of the department a more permissive policy according to his/her user name and password, regardless of the computer into which he/she is logged. Per computer groups: Defining your policies by computers enables the protection of the endpoints of your organization's computers regardless of the user who is logged in. SafeGuard Configuration Protection enforces policies as follows: it first applies a user policy, if one exists for the user that is currently logged in. If not, SafeGuard Configuration Protection looks for a policy that applies to the computer, and uses it, if found. This means that when no user is logged in, the computer-bound policy is used. It is therefore advised to distribute user-based policies, so that a user is given the same policy regardless of the computer into which he or she is logged, and to set computer based policies that are more restrictive. These computer-based policies should still grant access to such devices as a mouse and keyboard, to be used when no user, or a user outside of the domain, is logged in. The initial configuration of the SafeGuard Configuration Protection Client allows all port and device activity, meaning that nothing is blocked. A permissive configuration is necessary so that all port activity is not automatically blocked immediately following the installation of the SafeGuard Configuration Protection Client. This means that until you actually define and distribute policies to your endpoints (per user or per computer), the machine that was just installed with SafeGuard Configuration Protection Client will continue to operate as before (no blocking of ports and devices). 146 SafeGuard® Enterprise 5.50, Administrator help Note: The machine policy is used as fallback policy in case the user policy cannot be used or is being tampered. It is therefore recommended to create both machine and user policy while the user policy is the more permissive one. Note: Depending on the endpoint computer, it can take several seconds for the SafeGuard Configuration Protection Client to enforce a change of policies after logon. This means in case the machine policy is more restrictive than the user policy it takes a few seconds before the user gains access to the devices. 16.3.4 Step 3: Create a policy Policies are created as described for all other policies. 16.3.5 Step 4: Define port control This step includes setting port permissions as well as hybrid network bridging permissions. Port permissions SafeGuard Configuration Protection enables positive security by allowing access to all ports in all computers to which a policy is distributed unless that policy specifies that access to that port is blocked, as follows. For each port (USB, FireWire, PCMCIA, Secure Digital, Serial, Parallel, Modem, WLAN, IrDA, or Bluetooth), you can specify the following: Allow: This option specifies that the port can be used for any purpose, without any restrictions on this communication channel. Block: This option means that no access can be performed through this port. The port is unavailable as if its wires were cut. Restrict: For USB, FireWire, PCMCIA, and WLAN ports you also have the option to specify that access to ports of this type is Restricted. A Restricted setting enables you to define more specifically (meaning with higher granularity) which devices or connections are allowed to access the port. For example, you can specify that only USB devices of a specific model or even specific USB devices (meaning distinct devices with a unique serial number) are allowed access. For physical ports, this is done using the Device Control option described in Step 5: Define Device Control and the Storage Control option described in Step 6: Define Storage Control. For wireless ports, this is done using the WLAN Control option described in Step 8: Define WLAN Control. Note: The Device Control and WLAN Control aspects of a policy only apply to ports that are restricted. The Storage Control aspect of a policy applies both to restricted and allowed ports. For each port, specify whether its action type is Allow, Block, or Restrict by selecting the appropriate option in the drop-down menu. 147 SafeGuard® Enterprise 5.50, Administrator help Note: Internal ports such as storage busses such as IDE, SCSI, ATA and S-ATA, which are used to connect internal hard disk drives as well as PCI and PCI-X are allowed by default. Note: The settings for SecureDigital in the Physical Ports section are relevant when SecureDigital is used as a port. In case SecureDigital is connected through a USB adapter, it becomes a USB mass storage device. If SecureDigital is connected directly to the PC or laptop, recognition depends on the actual PC or laptop model. Hybrid Network Bridging permissions SafeGuard Configuration Protection allows administrators to control and prevent simultaneous use of various networking protocols that can lead to inadvertent or intentional hybrid network bridging (such as WLAN bridging and 3G card bridging). Configuring SafeGuard Configuration Protection Clients to block access to WLAN, Bluetooth, Modems, or IrDA links while the main wired TCP/IP network interface is connected to a network enables users to employ certain networking protocols only when they are disconnected from the network - avoiding the creation and potential abuse of a hybrid network bridge. Hybrid Network Bridging permissions are set in the Anti Hybrid Network Bridging section. 16.3.6 Step 5: Define device control In the Port Control section, for USB, FireWire, and PCMCIA ports you can specify that access to ports of these types is restricted (this is true for WLAN ports, too, which is discussed in Step 8: Define WLAN Control). Selecting Restrict enables you to define more specifically, using the Device Control section, which devices are allowed to access these ports. The Device Control section enables you to specify which device types are allowed access, and to assign the corresponding White List, which you use to specify which device models or distinct devices are allowed access. If a device is not defined as allowed in one of the ways described below, then it is blocked. The Device Control aspect of a policy applies to all the ports that are Restricted. Device Control - settings All Devices (top area): in this area you can Allow, Restrict, or Block access to all device types. If you select Allow or Block for All Devices, the rest of the section is disabled. You can also Allow or Block hardware key loggers. Devices Types (middle area): if you have selected the Restrict option for All Devices as described in the previous paragraph, this option enables you to allow or restrict access to a device according to its type. For example: Printing Devices, Network Adapters, or Imaging Devices. 148 SafeGuard® Enterprise 5.50, Administrator help The device types available for selection are built into SafeGuard Configuration Protection. If you would like to allow a device that is not of one of the types listed here, add it to your list of approved devices – the White List - using the Approved Model or the Distinct Devices option, described below. A description of the supported Device Types is provided in Supported Device Types. Unknown Devices (bottom area): This option enables you to determine whether access to unknown devices is granted or not. Device Control - White List The section offers to assign a White List for Device Models and/or a White List for Distinct Devices: White List for Device Models: This option refers to the model of a specific device type, such as a specific model of HP printers, such as LaserJet 4050N. Specify a White List file containing such devices. White List for Distinct Devices: This option refers to distinct devices with a unique serial number, meaning an actual specific device. Specify a White List file containing such devices. For example: the CEO’s personal printer may be permitted to connect, while other printing devices are not. Note: This section is disabled whenever you select Allow or Block in the All Devices option. See Defining Device Control. Note: In cases where a device belongs to more than one group, and those groups have the same permissions, SafeGuard Configuration Protection will choose between the groups arbitrarily. Defining device control 1. In the All Devices section, specify in the drop-down menu whether All Devices are Allowed, Restricted, or Blocked. Note: Select Allow or Block when you do not want to apply granular device control at this point in time. Alternatively, use this option when you wish to override existing granular definitions but want to return to them at a later time. 2. If you select Allow or Block for All Devices, there is nothing more you need to do in the Device Control section and you can now skip to Step 6: Define Storage Control. 3. If you selected Restrict for All Devices, define whether Hardware Key Loggers are Allowed or Blocked. Note: If the SafeGuard Configuration Protection Client suspects a USB Hardware Key Logger is connected to the keyboard, and Hardware Key Loggers are Blocked, the keyboard is blocked, too. To activate the keyboard, advise the user to connect it directly to the computer. 149 SafeGuard® Enterprise 5.50, Administrator help Note: When you block Hardware Key Loggers, both USB and PS/2 Key Loggers are blocked. When SafeGuard Configuration Protection Client protects against PS/2 Key Loggers, no user message is displayed. Nevertheless, the Key Logger device is rendered useless, since the information it logs is scrambled. In addition, note that when a PS/2 Key Logger is blocked while working with a PS/2 Keyboard Video Mouse (KVM), the KVM switching between computers will not work from the keyboard. You can switch computers by pressing the KVM itself. 4. If you selected Restrict for All Devices, set permissions for each Device Type in the Device Types section as follows: a) Allow: allows all devices of this type. b) Restrict: all devices are blocked unless they are specifically approved in the White List described in Approving Devices and WLAN Connections. 5. Select the White List for Device Models and White List for Distinct Devices to add to your allowed devices in the White List as described in White Lists - Approving Devices and WLAN Connections. 16.3.7 Step 6: Define storage control Storage devices may typically be the main conduits for information leakage in an organization. SafeGuard Configuration Protection enables you to control access by allowing full access, or blocking any device that is identified as a storage device. This includes removable media such as USB Memory Sticks, digital cameras and so on, as well as traditional devices, such as floppy drives, CD/ DVD drives, external hard drives, and tape drives. The Storage Control aspect of a policy is enforced across all ports through which a storage device can connect. This includes Allowed or Restricted ports, as well as ports that are not protected by SafeGuard Configuration Protection. On a port that is Blocked all storage devices are blocked, since blocking a port is similar to cutting its wires. Note: Since attacks and leakage directly via internal hard drives is not common, SafeGuard Configuration Protection does not handle blocking or restricting of these drives, so as not to disrupt ongoing work. 150 SafeGuard® Enterprise 5.50, Administrator help Storage control - settings This section includes the following areas: 1. All Storage Devices: in this area you can Allow, Restrict, or Block access to all storage devices. If you select Allow or Block for All Storage Devices, the rest of the section is disabled. You can also determine whether you want to allow or block the Autorun feature available on some storage devices such as CD/DVD. 2. Storage Types: if you have selected the Restrict option for All Storage Devices, this option enables you to allow, or restrict access to a storage device according to its type. For example: Removable Devices or CD/DVD Drives. The device types available for selection are built into SafeGuard Configuration Protection and include the following types and options: a) Removable Media: Applies to all plug-and-play storage devices, such as USB Memory Sticks, Digital Camera, Portable MP3 players, and so on. b) Allow smart functionality of Removable Media: Set this option to Allow to allow the usage of removable media that implement smart functionality. Set this option to Block to block the smart functionality of such devices. c) External Hard Drives d) CD/DVD Drives e) Floppy Devices f) Tape Devices Removable Media, External Hard Drives, CD/DVD Drives and Floppy Drives can additionally be set to Read Only. Use the White List to approve the usage of specific Storage Models or Distinct Storage Devices. A description of the supported Device Types is provided in Supported Device Types. For an explanation of how to define options in this section refer to Defining Storage Control. Storage Control - White List The section offers to assign a White List for Storage Device Models and/or a White List for Distinct Storage Devices: 1. White List for Storage Device Models: This option refers to the model of a specific storage device type, such as a specific USB Memory Stick model. 2. White List for Distinct Storage Devices: Distinct storage devices with a unique serial number, meaning an actual specific device. For example: the CEO's personal USB Memory Stick may be permitted to connect, while other USB Memory Sticks devices are not. 151 SafeGuard® Enterprise 5.50, Administrator help Note: This section is disabled whenever you select the Allow or Block option for All Storage Devices. Note: Select Allow or Block when you do not want to apply granular storage device control at this point in time, but plan to define it later on. Alternatively, use this option when you wish to override existing granular definitions but want to return to them at a later time. 16.3.8 Step 7: Define WLAN control In addition to devices, SafeGuard Configuration Protection controls and monitors your WLAN connections in order to ensure that endpoint computers use authorized, secure connections only. In the Port Control section, you can specify that access to a WLAN port is Restricted. Selecting Restricted enables you to define more specifically, using the WLAN Connection Types section, which networks are allowed to access this port. Note: When restricting the use of WLAN as a port, SafeGuard Configuration Protection monitors and regulates WLAN connections over Microsoft WZC infrastructure. Any device driver that would try to access the network card, not using WZC will be blocked. Note: If you are using a lot of WLAN cards which enforce proprietary drivers you can only Allow or Block WLAN as a port. WLAN Control - settings WLAN Connection Types: this option enables you to Allow or Restrict access to WLAN networks, and to Allow or Block WLAN Peer-to-Peer connections. In the case of WLAN networks, if you choose Restrict you may further specify which specific networks are approved. WLAN Control - White List White List for WLAN: This option refers to distinct networks, including their authentication and encryption properties. Note: This section is disabled whenever you select the Allow option for networks. 152 SafeGuard® Enterprise 5.50, Administrator help Defining WLAN control To define WLAN control: 1. Go to the WLAN option in the Wireless Ports section. Set WLAN to Restrict. This enables the options below WLAN Connection Types. 2. In the WLAN Connection Types section set permissions for WLAN Networks (Infrastructure) as follows: a) Allow: allows connection to all WLAN networks. b) Restrict: all networks are blocked unless they are specifically approved in the White List as described in White Lists - Approving Devices and WLAN Connections. 3. In the WLAN Connection Types section set permissions for Peer-to-Peer (Ad Hoc) as follows: a) Allow: allows all peer-to-peer WLAN connections. b) Block: blocks all peer-to-peer WLAN connections. In this option, more granular permissions are not available. 16.3.9 Step 8: Define File Control SafeGuard Configuration Protection allows you to set permissions not only for storage devices, but also for the files transferred to and from these devices. This is achieved by inspecting files for their type as they are transferred to/from external storage devices. This technology allows for highly reliable classification of files by inspecting the file header contents rather than using file extensions, thus preventing users from easily bypassing the protection by renaming file extensions. By inspecting both files downloaded to external storage devices and those uploaded to the protected endpoint, multiple benefits can be achieved: An additional protection layer to prevent data leakage Prevention of the introduction of viruses/malware via external storage devices Prevention of the introduction of inappropriate content via external storage devices, e.g. unlicensed software, unlicensed content (e.g. music and movies), non work-related content such as private pictures etc. With this feature, you can define policies which approve/block specific file types on the inbound and outbound channels. 153 SafeGuard® Enterprise 5.50, Administrator help SafeGuard Configuration Protection’s File Control includes the following: File Type Control - the ability to control transfer of files according to their type. File Control is applicable to removable storage devices, external hard disks and CD/DVD. File Control - settings This section includes the following areas: 1. Storage Type: in this area you can Apply file type control to storage types or Exclude storage types from file type control. The storage types available for selection are built into SafeGuard Configuration Protection and include the following: a) Reading from removables b) Writing to removables c) Reading from external hard drives d) Writing to external hard drives e) Reading from CD/DVD media 2. If you select Apply or Exclude for at least one of the storage types the rest of the section (File Types) is activated. You can set the following permissions for each file type: a) Allow b) Read Only c) Write Only d) Block The permissions for file types apply to all storage types to which you have applied file control in the Storage Types section. 154 SafeGuard® Enterprise 5.50, Administrator help The following table lists the file types and extensions supported by SafeGuard Configuration Protection File Type Control. 155 File Type Extensions Description Microsoft Office DOC Microsoft Word Document DOCX Microsoft Word Document DOCM Microsoft Word Document DOT Microsoft Word Template DOTX Microsoft Word Template DOTM Microsoft Word Template RTF Rich Text Format PPT Microsoft PowerPoint Presentation PPTX Microsoft PowerPoint Presentation PPTM Microsoft PowerPoint Presentation POT Microsoft PowerPoint Template POTX Microsoft PowerPoint Template POTM Microsoft PowerPoint Template PPS Microsoft PowerPoint Show PPSX Microsoft PowerPoint Show PPSM Microsoft PowerPoint Show PPA Microsoft PowerPoint Add-In PPAM Microsoft PowerPoint Add-In XLS Microsoft Excel Workbook XLSX Microsoft Excel Workbook XLSM Microsoft Excel Workbook XLSB Microsoft Excel Workbook XLT Microsoft Excel Template XLTX Microsoft Excel Template XLTM Microsoft Excel Template XLA Microsoft Excel Add-In XLAM Microsoft Excel Add-In MPP Microsoft Project Project SafeGuard® Enterprise 5.50, Administrator help Published Documents Web Pages Images MPT Microsoft Project Template VSD Microsoft Visio Drawing VDX Microsoft Visio Drawing VSS Microsoft Visio Stencil VSX Microsoft Visio Stencil VST Microsoft Visio Template VTX Microsoft Visio Template PUB Microsoft Publisher ONE Microsoft OneNote Sections ADP Microsoft Access Project ADE Microsoft Access Project Extension PDF Adobe Acrobat Document PS Post Script Document EPS Encapsulated Post Script HTML HTML Web Page HTM HTML Web Page MHT Archived Web Page MHTML Archived Web Page PHP PHP Script HLP Windows Help File CHM Compiled Help File ASP Active Server Page ASPX ASP.NET Web Page ASMX ASP.NET Webservices JHTML Java HTML Web Page JSP Java Server Page JPG JPEG Image JPEG JPEG Image GIF GIF Image BMP Bitmap Image DIB Device Independent Bitmap Image 156 SafeGuard® Enterprise 5.50, Administrator help Multimedia 157 PNG PNG Image TIF Tagged Image Format TIFF Tagged Image Format MDI Office Document Imaging File JNG JNG Image MNG MNG Image ICO Windows Icon CUR Windows Cursor WMF Windows Metafile Image EMF Enhanced Windows Metafile Image FH9 Macromedia Freehand 9 Graphics JP2 JPEG-2000 Image PBM Portable Bitmap PGM Portable Graymap Bitmap PPM Portable Pixelmap Bitmap PSD Adobe Photoshop Graphics CDR CorelDRAW Vector Graphics SVG Scalable Vector Graphics WAV Waveform Audio WMA Windows Media Audio MP2 MPEG Audio MP3 MPEG Audio AIFF Audio Interchange AIF Audio Interchange AU AU Audio RA RealMedia Streaming Media MID Musical Instrument Digital Sound MIDI Musical Instrument Digital Sound RMI Musical Instrument Digital Sound SDS Musical Instrument Digital Sound Sample VOC Creative Lab's Soundblaster Audio SafeGuard® Enterprise 5.50, Administrator help Text & Program Code OGG Ogg Vorbis Codec Audio VOX Dialogic Audio FLAC Free Loseless Codec Audio MPEG MPEG Multimedia MPG MPEG Multimedia AVI Audio Video Interleave ASF Advanced Streaming Format WMV Windows Media Multimedia MOV QuickTime Video Clip SWF Flash Animation File FLI FLIC Animation FLC FLIC Animation TXT Text File CSV Formatted Text (Comma Delimited) PRN Formatted Text (Space Delimited) CPP C++ Program Code C C/C++ Program Code H C/Java Header File XML XML File F FORTRAN Program Code T90 FORTRAN Program Code MAKEFILE Compilation Control File MAKEFILE.IN Compilation Control File PL1 PL1 Program Code ASM Assembler Program Code PAS PASCAL Program Code JAVA JAVA Program Code M4 Meta4 Program Code BCPL BCPL Program Code CS Visual C#.NET Program Code PL Perl Program Code 158 SafeGuard® Enterprise 5.50, Administrator help Executables Compressed Archives 159 PM Perl Program Code Module PY Python Program Code PDB Visual C++/.NET Program Database BAS BASIC Program Code VB Visual Basic Program Code VBS VBScript Script JS JavaScript Source Code EXE Executable DLL Dynamic Link Library PIF Windows Program Information File BAT Batch COM Command OCX ActiveX -

approving devices and WLAN connections The explanations in the following sections refer to adding approved devices to the Device Control White List and adding approved storage devices to the Storage Control White List. Where differences exist between adding storage and non-storage devices, they are pointed out and explained. Explanations on how to add approved WLAN networks can be found in Adding WLAN Connections. SafeGuard Configuration Protection provides you with three levels of permissions: Devices Types and Storage Types: This option enables you to allow or restrict access to an endpoint according to the type of device that is connected. For example: Removable Media, Network Adapters, Human Interface devices (such as a mouse), or Imaging Devices. The device types and storage types available for selection are built into SafeGuard Configuration Protection and are found in the Device Control section and the Storage Control section. A device type may be allowed (default), blocked, or restricted. If you restrict a device type, all devices of this type are blocked unless specifically approved in a White List. White List for Device Models: This option refers to approving models of devices or storage devices, such as all HP printers or all M-Systems USB Memory Sticks. White List for Distinct Devices: This option refers to approving distinct devices or storage devices, each with its own unique serial number, meaning each is an actual specific device. For example, if you wish to approve the use of the CEO’s USB Memory Stick and block all other USB Memory Stick devices, you should set the Removable Media storage type to Restrict, and then enter the identifying parameters of the CEO's USB Memory Stick in a White List for specific Distinct Storage Devices. This section describes how to create a White List and how to add approved models or distinct devices to a White List either from the list of devices whose usage was detected in your organization by SafeGuard PortAuditor, or manually. 162 SafeGuard® Enterprise 5.50, Administrator help 16.4.1 Creating White Lists To register a White List, proceed as follows: 1. Select White List in the policy navigation area. 2. In the context menu of White List, click New > White List. 3. In field White List name enter a name for the White List. 4. Selecting the White List type White Lists can be created for: Device Models Distinct Devices Storage Device Models Distinct Storage Devices WLAN Networks The individual White Lists can be selected when defining policy settings. 5. Specify whether you want to create the White List manually or whether you intend to use the result of a scan of the computers by SafeGuard PortAuditor as a source. Note: The results of the SafeGuard PortAuditor scan have to be available (XML file), if you intend to create the White List based on this source. a) Create White List manually If you select this option, an empty White List will be opened in the SafeGuard Management Center after clicking OK. In this empty White List you can create entries manually. b) Import from SafeGuard Port Auditor Result If you select this option, the result of the scan by SafeGuard PortAuditor will be imported. 163 You can select the file provided by SafeGuard PortAuditor via the [...] button. After clicking OK the contents of the imported file will be displayed in the SafeGuard Management Center. SafeGuard® Enterprise 5.50, Administrator help 16.4.2 Adding a device using a SafeGuard PortAuditor file Prerequisite: Creating a device information file In order to create a file that contains the information about the devices you wish to approve, use SafeGuard PortAuditor to scan the required computers. SafeGuard PortAuditor scans the selected computers and reports on all devices and WLAN networks currently or previously connected to those computers. The audit results are stored in an .XML file. To learn about SafeGuard PortAuditor refer to SafeGuard PortAuditor 3.2 User Guide. 16.4.2.1 Step 1: Get device information In this step you specify the file from which to gather the information about devices that will be added, i.e. the location of the SafeGuard PortAuditor .XML file that contains the required device information. After you have selected the required file using [...], click OK to continue. 16.4.2.2 Step 2: Select devices Step 2 displays a table of the devices detected on the endpoints in your network and enables you to select the ones to add. The table is divided into categories, depending on whether the White List to which you are adding devices is a Device Models White List or a Distinct Devices White List, and whether you are adding storage devices or non-storage devices. Selectable devices have a check box beside them which you should check if you want to approve the device model or the distinct device, as the case may be. You can also select or deselect all or marked devices when you right-click in the table. Note: You cannot add storage devices to the Device Control White List. Note: You cannot add devices or storage devices without a distinct ID to a Distinct Devices White List. Occasionally, a device may not be identified as a storage device by SafeGuard PortAuditor. This may happen, for example, when a device class has not been embedded by the manufacturer. In this case, if you know that it is in fact storage, you may add it to your policy's storage white list. You must avoid adding storage devices to a Device Control White List or adding non-storage devices to a Storage Control White List, as they will be ignored by the SafeGuard Configuration Protection Client. Note: When you add a device that already belongs to another device White List in this policy, and the White List permissions differ, the most permissive will apply. 164 SafeGuard® Enterprise 5.50, Administrator help 16.4.2.3 Step 3: Save White List Save the White List by clicking the icon in the SafeGuard Enterprise toolbar. Using the Modify contents button you can insert the contents from another file into the White List. New entries will be appended at the end of the White List. 16.4.3 Adding a device manually If you have created an empty White List, you have to add the entries manually. Or if you want to add devices to an existing White List, as in the case of devices that have not been connected to any endpoint in your organization and therefore do not appear in the SafeGuard PortAuditor audit results, you also have to add them manually. The following instructions apply both when adding storage devices (in Storage Control) and when adding non-storage devices (in Device Control). Note: When you add a device that already belongs to another device White List in this policy, and the White List permissions differ, the most permissive will apply. To add a device manually: 1. Click the icon in the SafeGuard Enterprise toolbar to add a new entry to the White List. 2. Enter the required information in the following fields: a) Port – optional b) Device Description – optional c) Device Information – optional d) Vendor (Vendor ID) – optional e) Product (Product ID) – optional f) Hardware ID/Instance ID – required Double-check that you have entered the correct data in all fields and save the White List. Selecting an entry and clicking the from the White List. icon in the SafeGuard Enterprise toolbar removes the entry Note: Vendor ID (VID), Product ID (PID), Hardware ID (HID) and Instance ID (IID) can be found in the SafeGuard PortAuditor scan results, on a sticker attached to the product itself or in Windows Device Manager. 165 SafeGuard® Enterprise 5.50, Administrator help 16.4.4 Adding WLAN connections WLAN links are added to the WLAN Network White List in much the same way this is done in the case of devices; add a WLAN White list, then add approved links to this White List using the data from the SafeGuard Port Auditor file, or manually. 16.4.4.1 Adding a WLAN link manually If you want to add WLAN links that were not detected by SafeGuard PortAuditor, and as a result cannot be added using the import mechanism, you can do so manually. Entering WLAN Network Information Now you define the parameters a network must match in order for it to be approved for connection. You can identify a network by its name and/or by its MAC address. After you enter a network name or a MAC address, you can also specify authentication and data encryption parameters which must be matched. Only networks matching all the parameters are approved. To add a WLAN link manually: 1. Open the White List for WLAN connections. 2. Click the icon in the SafeGuard Enterprise tool bar to add a new entry to the White List. 3. Enter Network Name, MAC Address or both. It is required to add information to at least one of the two fields. 4. If you want to specify the Network Name only, enter the name and continue with step 6. 5. If you want to specify the MAC Address only, enter the address and continue with step 6. 6. To define security settings, specify the required Authentication and Data Encryption settings from the dropdown list. Adding information to these fields is optional. Note: The Data Encryption options available in the dropdown list depend on the selected Authentication type. For example, for WPA authentication, the encryption options are TKIP or AES, whereas in the case of 802.1X authentication only WEP encryption is available for selection. 7. Double-check that you have entered the correct data in all the fields and save the White List. 166 SafeGuard® Enterprise 5.50, Administrator help 16.5 Supported device types This chapter lists the device types that SafeGuard Configuration Protection provides for your selection when building a policy. For non-storage devices you can restrict the usage of devices on USB, FireWire, and PCMCIA ports. SafeGuard Configuration Protection provides a selection of built-in types in the Device Control window to enable you to define which types of devices are approved or blocked. If you require control of a device type that is not listed here, you can use the Distinct Device restriction feature described in White Lists -Approving Devices and WLAN Connections. For storage devices, SafeGuard PortAuditor is able in most cases to identify whether a device is a storage device or a non-storage device, by detecting its volume, or using its embedded class data. This ability helps categorize and organize device lists into storage devices and simple (nonstorage) devices for your selection, thus enabling you to define your policy more easily. SafeGuard Configuration Protection provides a selection of built-in types in the Storage Control window to enable you to define which types of devices will be approved or blocked. The following device type lists are divided into non-Storage devices and storage devices. 16.5.1 Non-storage device types The following lists the non-storage built-in device types for which a policy can be defined in SafeGuard Configuration Protection. Note: Device Control for non-storage devices can only be defined for USB, FireWire, and PCMCIA ports. 1. Human Interface Device – devices used to control the operation of computer systems. Typical examples include keyboards and pointing devices, such as: mouse, trackballs, and joysticks. 2. Printing Devices – Printers connected over USB, PCMCIA, or FireWire. 3. Personal Data Assistants (PDAs) - These include: a) Windows Mobile / Pocket PC Devices b) Blackberry Devices c) Palm OS Devices 4. Mobile Phones – New models of cellular phones, categorized in USB as 'Wireless USB Devices'. 5. Network Adapters - Communication devices such as: Ethernet network adapters, WLAN adapters, and USB-connected ADSL and cable modems. 167 SafeGuard® Enterprise 5.50, Administrator help 6. Imaging Devices - Primarily devices such as scanners and digital still cameras. 7. Audio/Video Devices - devices such as: microphones, telephones, volume controls, web cameras, digital camcorders, digital television tuners and digital still-image cameras that support video streaming. 8. Smartcards - smartcard devices. 9. Content Security Devices - used to provide special security features, such as strong authentication, biometric identification and software licensing. 16.5.2 Storage device types Protection of storage devices applies to all non-blocked ports, meaning that it applies to the specified storage device no matter to which port it is connected as long as that port is not defined as blocked. Note: Device Control for storage devices can be defined for any port type including, for example, parallel ports, USB, FireWire, and PCMCIA ports. The following lists the storage built-in device types that are supported by SafeGuard Configuration Protection. Removable Media – These devices range from storage-only devices, such as USB Memory Sticks and SD flash cards, to devices that have a unique purpose, but appear to the computer as a new storage drive, such as portable digital music players, digital cameras and PDAs. External Hard Drives – hard disk devices which are externally attached (e.g. via USB). CD/DVD Drives – both internally and externally attached. Floppy Devices – both internally and externally attached. Tape Devices – both internally and externally attached. 168 SafeGuard® Enterprise 5.50, Administrator help 17 User-computer assignment SafeGuard Enterprise manages the information about which users are allowed to log on to a particular machine in a list which is referred to below as the UMA (User-Machine-Assignment). For a user to be included in the UMA, they must have logged on once to a computer on which SafeGuard Enterprise has been installed and be registered in the SafeGuard Management Center as a “full” user in terms of SafeGuard Enterprise. A “full” user is one for whom a certificate has been generated after the first logon and for whom a key ring has been created. Only then can this user data be replicated on other computers. After replication, the user can log on to this computer at the POA. In the standard setting, the first user to log on to the computer after the installation of SafeGuard Enterprise is entered in the UMA as the owner of that computer. This attribute allows the user, having authenticated themselves at Power-on Authentication, to enable other users to log on to that computer (see Importing further users on page 181). They will also be added to the UMA for this computer. An automatic list is thereby generated which determines which user is allowed to log on to which computer. This list can be edited in the SafeGuard Management Center. 17.1 User-computer assignment in the SafeGuard Management Center Users can be allocated to specific computers in the SafeGuard Management Center. If a user is assigned to a computer in the SafeGuard Management Center (or vice versa) this allocation is incorporated into the UMA. The user data (certificate, key, etc.) is replicated on this computer and the user can log on to this computer. When setting this assignment, the administrator can also specify who can allow other users to log on to this computer. Under Type the Management Center indicates how the user was added to the SafeGuard Enterprise database. Adopted means that the user has been added to the UMA on a endpoint computer. Note: If no one is assigned in the Management Center and no user is specified as the owner, the first user to log on after the installation of SafeGuard Enterprise on the computer is entered as the owner. This user can then allow further users to log on to this computer, see Importing further users on page 181. If users are assigned to this computer in the Management Center at a later date, they can then log on at the Power-on Authentication. Nevertheless such users must be full users (with existing certificate and key). The owner of the computer does not need to assign access entitlements in this case. 169 SafeGuard® Enterprise 5.50, Administrator help The following settings are used to specify who is allowed to add users to the UMA: Ownership: If this setting is activated, the user can be registered as the owner of a computer. User is Owner: This setting means that this user is entered in the UMA as the owner. No further users can be included in UMA. Only one user per computer can be entered in the UMA as the owner. The Import of new users allowed for policy setting in policies of the type Specific Machine Settings determines who is allowed to add further users to the UMA. Import of new users allowed for Nobody Even the user entered as the owner cannot add more users to the UMA. The option for an owner to add further users is switched off. Owner (default setting) Users can only be added to the UMA by the owner. Note: A Security Officer may always add users in the SafeGuard Management Center. Everybody Lifts the restriction that users may only be added by the owner. 170 SafeGuard® Enterprise 5.50, Administrator help Example: The following example shows how you can assign logon entitlements in SafeGuard Management Center to just three users (User_a, User_b, User_c) for Computer_ABC. First: Specify the response you require in SafeGuard Enterprise Management Center. SafeGuard Enterprise is installed on all endpoint computers during the night. In the morning, the users are to log on to the computer according to their logon details. 1. In SafeGuard Management Center, assign User_a, User_b and User_c to Computer_ABC. (Users & Computers -> Select computer_ABC -> Assign user via Drag&Drop). You have thereby specified a UMA. 2. In a computer policy select the setting Import of new users allowed for to Nobody. Since User_a, User_b and User_c are not allowed to add new users is not necessary to specify a user as an owner. 3. Assign the policy to the computer and/or to a point within the directory structure at which it will be active for the computer. When the first user logs on to Computer_ABC (see Logging on on page 179), an autologon is implemented for the POA. The computer policies are sent to the endpoint computer. Since User_a is included in the UMA and will become a full user when logging on to Windows. The user's policies, certificates and keys are sent to the endpoint computer. The POA is activated. Note: The user can check the status message in the SafeGuard System Tray Icon (balloon tool tip) when this process has completed. User_a is now a full user in terms of SafeGuard Enterprise and after the first logon can authenticate him or herself at the POA and is automatically logged on. User_a now leaves the computer and User_b wants to log on. As the POA is activated, there is no more autologon. User_b and User_c have two options for gaining access to this computer. a) User_a deactivates the Passthrough Logon to Windows option in the POA logon dialog and logs on. b) User_b uses Challenge/Response to log on at the POA. In both cases, the Windows logon dialog is displayed. 171 SafeGuard® Enterprise 5.50, Administrator help User_b can enter his or her Windows credentials. The user's policies, certificates and keys are sent to the endpoint computer. The user is activated in the POA. User_b is now a full user in terms of SafeGuard Enterprise and after the first logon can authenticate themselves at the POA and will be automatically logged on. While the computer policy specifies that no one can import users to this computer, since these users are already in the UMA, User_b and User_c nevertheless gain “full” user status at the Windows logon and are activated in the POA. No other users will be added to the UMA or will ever therefore be able to authenticate themselves at the Power-on Authentication. Any users logging on to Windows who are not User_a, User_b or User_c are excluded from the UMA in this scenario and will never be active in the POA. Users can always be added later on in the SafeGuard Management Center. However, their key ring will not be available after the first logon as synchronisation will only be triggered by this first logon. After logging on again, the key ring will be available and the users can access their computers according to the policies applying. If they have never successfully logged on to an endpoint computer, they can be added as described above. Block User If you activate the check box in the Block User column the user is no longer allowed to log on to the relevant computer. Furthermore, the computer will be automatically shut down, if the relevant user is logged on as soon as the policy with this setting becomes active on the computer. 17.1.1 Groups Computer groups can also be assigned to a user (account) and/or user groups can be assigned to a computer in the SafeGuard Management Center. Example: Service account Therefore it is for instance possible to use a single service account to service a large number of computers. For this purpose the computers concerned must be in a single group. This group is then assigned to a service account (user). The owner of the service account can then log on to all computers within this group Also, by assigning a group containing different users, these users can then log on to a specific computer in a single step. 172 SafeGuard® Enterprise 5.50, Administrator help 17.2 Assignment of user and computer groups To assign a user to a group of computers, proceed as follows: Note: You can assign individual users to a computer or vice versa using the same process as for groups. 1. Click Users & Computers. 2. To assign a group of computers to single user, select the user. 3. Click the Computer tab in the action area. All computers and computer groups are displayed under Available computers. 4. Drag the selected groups from the list of available groups into the action area. 5. You will see a dialog asking whether the user should be the owner of all computers. If there is no specified owner in SafeGuard Enterprise Management, the first user to log on to this computer is automatically entered as the owner. The user is the entitled to allow other users to access this computer. The condition is that the user “Can be owner”. Answering Yes to this question means that the first user to log on to this computer becomes the owner and can allow access to other users. Answering No to this question means that the user will not be the owner of this computer. It is not generally necessary for a service account owner to be the owner of the computer. This setting can be changed after initial assignment. 6. After answering the question, all computers from the assigned group are displayed in the action area. The user can log on to all computers assigned in this way. A user group can be assigned to a single computer using the same process. 173 SafeGuard® Enterprise 5.50, Administrator help 18 Tokens and smartcards Tokens and smartcards are hardware components that help an authorized user with the authentication process on a computer system. They can be used to store certificates, digital signatures and biometric details. Data cannot be manipulated. Nowadays, authentication using a user name and password often no longer meets the customer's need to have the best possible protection against external access. So, as an alternative and to improve security, SafeGuard Enterprise provides logon using tokens and smartcards. Token logon is based on the principle of a two-stage authentication: A user has a token (ownership), but can only use the token, if they know the specific token password (knowledge). When a token or smartcard is used, users only need the token and a PIN for authentication. Note: From SafeGuard Enterprise's perspective, smartcards and tokens are treated in the same way. So the terms “token” and “smartcard” can be understood as the same thing in the product and in the manual. Tokens are supported: in the Power-on Authentication at operating system level to log on to the Management Center When a token is issued to a user, data such as the manufacturer, type, serial number, logon data and certificates are stored in the SafeGuard Enterprise database. In such cases, tokens are identified by the serial number and then recognized in SafeGuard Enterprise. This gives important benefits: It is evident which tokens are in circulation and which users they are assigned to. It is evident when they were issued. If a token is lost, the Security Officer can identify it and block it for authentication. This prevents the misuse of data. However, the Security Officer can use Challenge/Response to temporarily allow logon without a token, e.g. if a user has forgotten their PIN. 174 SafeGuard® Enterprise 5.50, Administrator help 18.1 Smartcards To be able to use a smartcard with SafeGuard Enterprise, a card reader and a card driver for the PC are both required as well as the smartcard. Also, for the smartcards and card readers to communicate with SafeGuard Enterprise certain middleware, in the form of a PKCS#11 module, is required. 18.1.1 Smartcards and smartcard readers/drivers SafeGuard Enterprise supports non-cryptographic and cryptographic logon procedures with Power-on Authentication. With non-cryptographic smartcards, user ID and password are stored on the card. Cryptographic smartcards are used to authenticate RSA key pairs (certificates). Windows On the Windows operating system level, PC/SC-compatible card readers are supported. The PC/SC interface regulates the communication between the PC and smartcard. Many of these card readers are already a part of the Windows installation. Smartcards require PKCS#11 compatible smartcard drivers if they are to be supported by SafeGuard Enterprise. Power-on Authentication Refer to the Release Notes for a detailed list of all the supported smartcards, smartcard readers and smartcard drivers. 175 With Power-on Authentication, the PC/SC interface is supported which regulates the communication between PC and smartcard. The supported smartcard drivers are a fixed implementation and users may not add other drivers. The appropriate smartcard drivers have to be enabled by means of a policy in SafeGuard Enterprise. The interface for smartcard readers is standardized and many card readers have a USB interface or an ExpressCard/54 interface and implement the CCID standard. In SafeGuard Enterprise this is a prerequisite to be supported with Power-on Authentication. Plus, on the driver side, the PKCS#11 module has to be supported. SafeGuard® Enterprise 5.50, Administrator help 18.1.2 Supported smartcards with Power-on Authentication SafeGuard Enterprise supports a large number of smartcards and smartcard readers, plus common smartcard drivers with Power-on Authentication. With SafeGuard Enterprise, tokens/ smartcards which support 2.048-bit RSA operations are supported. As support for smartcards is enhanced from release to release, the tokens and smartcards supported in whatever is the current version of SafeGuard Enterprise are listed in the Release Notes. 18.1.3 Supported middleware The middleware in the list below is supported via the relevant PKCS#11 module. PKCS#11 is a standardized interface for connecting cryptographic tokens/smartcards to different software. Here, it is used for the communication between cryptographic token/smartcard, the smartcard reader and SafeGuard Enterprise. .

The SafeGuard Enterprise Client configuration package must also be installed on the PC on which the Management Center is running. 18.2 USB tokens Like smartcards, USB tokens consist of a smartcard reader and a smartcard, both units being located in a single casing. 18.2.1 Supported USB tokens with Power-on Authentication SafeGuard Enterprise supports a wide range of USB tokens. As a prerequisite, the smartcard used must be supported by the Power-on Authentication of SafeGuard Enterprise and the respective drivers must be supported as well. The USB tokens also have to be supported by the relevant middleware. As support for tokens is enhanced from release to release, the tokens and smartcards supported in the respective version of SafeGuard Enterprise are listed in the Release Notes. 177 SafeGuard® Enterprise 5.50, Administrator help 18.3 Working with tokens Proceed as follows in order to be able to use tokens for authentication: 1. Initialize empty tokens 2. Issue tokens for users and security officers 3. Write certificates and keys on tokens 4. Define policies for tokens You can also use tokens that have data from a different application for authentication providing that there is enough storage space for the certificates and logon information on them. SafeGuard Enterprise provides you with the following features so that you can easily administer tokens: Display and filter token information Initialize, change, reset and block PINs Read and delete token data Block token 178 SafeGuard® Enterprise 5.50, Administrator help 18.4 Initializing a token Before an “empty”, unformatted token can be issued to a user in SafeGuard Enterprise, it needs to be prepared for use - i.e. initialized - according to the instructions provided by the token manufacturer. When it is initialized, basic information e.g. the standard PIN, is written to it. The token manufacturer's initialization software is used to do this. Please refer to the token manufacturer concerned for more information. 18.4.1 Installing middleware on the endpoint computer Next install the correct middleware, both on the PC which the SafeGuard Management Center is running on and the relevant user PC, see Supported middleware on page 176. 18.4.2 Activating middleware (PKCS#11 module) Before issuing the token you need to assign the correct middleware in form of the PKCS#11 module by defining a policy in the SafeGuard Management Center. You should do this both for the computer which the SafeGuard Management Center is running on and for the user PC. Only then can SafeGuard Enterprise communicate with the token. You can define the setting for PKCS#11 module, using a policy, as follows. Prerequisite: the middleware is installed on the relevant PC and the token has been initialized. The SafeGuard Enterprise Client configuration package must also be installed on the PC which the Management Center is running. In the SafeGuard Management Center, click Policies. 1. Plug the token into the USB interface. SafeGuard Enterprise reads in the token. 2. Create a new policy of the type Specific Machine Settings or select an existing policy of this type. 3. In the work area on the right-hand side, under Token support settings > Module Name, select the appropriate middleware. Save the settings. 4. Assign the policy. SafeGuard Enterprise can now communicate with the token and administer the token. The token can now be issued. 179 SafeGuard® Enterprise 5.50, Administrator help 18.5 Issuing a token When a token is issued in SafeGuard Enterprise, data is written on the token which is then used for authentication. This data consists of credentials and certificates. In SafeGuard Enterprise, tokens can be issued for these user roles: Tokens for normal users Tokens for Security Officers (SO) Both user and Security Officer (SO) can access the token. The user is the person who should use the token. Only the user can access private objects and keys. The SO can only access public objects, but can reset the user's PIN. 18.5.1 Issuing a token or smartcard to a user 180 SafeGuard® Enterprise 5.50, Administrator help Prerequisite: The token must be initialized and the relevant PKCS#11 module must be activated. The SafeGuard Enterprise Client configuration package must also be installed on the PC which the Management Center is running. Open the Management Center and click Users & Computers. 1. Connect the token to the USB interface. SafeGuard Enterprise reads in the token. 2. Mark the user for whom a token is to be issued, and open the Token Data tab in the work area on the right-hand side. 3. In the Token Data dialog, proceed as follows: a) Select the user ID and domain of the user selected and enter your Windows password. b) Click Issue Token. 4. In dialog Issue Token select the appropriate slot for the token. 5. Issue a new User PIN and repeat the entry. 6. Under SO PIN enter the standard PUK received from the manufacturer or the PIN issued when the token was initialized. Note: If you only fill in the User PIN (required) field, the user PIN must match the PIN which was issued when the token was initialized. You then have no need to repeat the user PIN or input a SO PIN. 7. Click Issue token now. The token is issued, the logon information written on the token and the token information saved in the SafeGuard Enterprise database. You can display the data in the Token area in tab Token Information. 181 SafeGuard® Enterprise 5.50, Administrator help 18.5.2 Issuing a token or smartcard to a Security Officer When SafeGuard Enterprise is installed for the first time, the first Security Officer (SO) already has the option of having themselves issued with a token and specifying the logon mode (see Installation Guide). For all other security officers, a token is issued in the SafeGuard Enterprise Management Center. Prerequisite: The token must be initialized and the relevant PKCS#11 module must be activated. You need the rights to be able to make entries for the SO. In the SafeGuard Management Center, click Security Officers. 1. Connect the token to the USB interface. SafeGuard Enterprise reads in the token. 2. In the navigation window on the left, mark Security Officer and in the context menu select New > New Officer. 3. If the SO is to authenticate either with or without a token, in the work area on the right-hand side activate Token logon: Optional. 4. If the SO is to only authenticate with the token, activate Token logon: Mandatory. With this setting, the private key remains on the token. The token must always be plugged in, or the system will need to be rebooted. 5. If you wish to create a new certificate, click Create. Enter the password for the certificate twice and confirm with OK. Specify the location for saving the certificate. 182 SafeGuard® Enterprise 5.50, Administrator help 6. If you wish to import certificates, click Import. Open the relevant certificate file. Searching is first done in a certificate file, then on the token. The certificates may remain in whatever the storage location is. 7. Activate the roles and domains that are to be assigned to the SO. 8. Confirm the entries with OK. The SO is created, the token is issued, the logon data is, depending on the setting, written on the token, and the token information is saved in the SafeGuard Enterprise database. You can display the data in the Token area in tab Token Information. 18.6 Putting certificates on a token or smartcard Not only logon information but also certificates can be written to a token. Just the private part of the certificate (.p12 file) may be saved on the token. However, users then normally can only access their private key when logging on with the token. It is recommended that PKI certificates are used. You can assign authentication data to different types of token: by generating certificates directly on the token by assigning data which is already on the token by importing certificates from a file Note: CA certificates cannot be obtained from a token and stored in the database or certificate store. If you wish (or need) to use CA certificates, these need to be available in file form and not just on a token. This also applies to CRLs (Certificate Revocation List). Moreover, the CA certificates must match the CRL on the token before users can log on to the computers concerned. Please check that the CA and CRL are correct. SafeGuard Enterprise does not carry out this check! SafeGuard Enterprise can then only communicate with expired certificates if old and new keys are present on the same card. 18.6.1 Generating certificates with tokens You can generate new certificates straight from the token if, for example, there is no certificate structure present. Note: If only the private part of the certificate is written on to the token, the user can only access their private key with the token. The private key then only resides on the token. If the token is lost, the private key can no longer be accessed. 183 SafeGuard® Enterprise 5.50, Administrator help Prerequisite: The token is issued. In the SafeGuard Management Center, click Users & Computers. 1. Plug the token into the USB interface. SafeGuard Enterprise reads in the token. 2. Mark the user for whom a certificate is to be generated, and open the Certificate tab in the work area on the right-hand side. 3. Click Generate and assign certificate by token. Note that the length of the key must match the size of the token. 4. Select the slot and enter the token PIN. Click Create. The token generates the certificate and assigns it to the user. 18.6.2 Assigning token certificates to a user If there are already certificates on the token which you wish to assign to the user, proceed as follows: Prerequisite: The token is issued. In the SafeGuard Management Center, click Users & Computers. 1. Plug the token into the USB interface. SafeGuard Enterprise reads in the token. 2. Mark the user for whom you want to assign a certificate, and open the Certificate tab in the work area on the right-hand side. 3. Click the Assign a certificate from a token icon in the SafeGuard Management Center toolbar. Select the relevant certificate from the list and enter the token's PIN. 4. Confirm with OK. The certificate is assigned to the user. 18.6.3 Putting a certificate from a file onto the token If you want to add the private part of the certificate (.p12 file) from a file to the token, proceed as follows: Prerequisite: The token is issued. In the SafeGuard Management Center, click Tokens. 184 SafeGuard® Enterprise 5.50, Administrator help 1. Plug the token into the USB interface. SafeGuard Enterprise reads in the token. 2. Mark the token to which you want to add the private part of the certificate and, in the work area on the right, open the Logon Information & Certificates tab. 3. Click the P12 to token icon in the SafeGuard Management Center toolbar. Select the relevant certificate file. 4. Enter the token's PIN and the password for the .p12 file and confirm with OK. The private part of the certificate is added to the token. Now you need to assign it to a user, see Assigning token certificates to a user on page 184. Note: For a token with Kerberos support you need to select this procedure. The certificate must be recognized by SafeGuard Enterprise and added to the token. If there is already an autogenerated certificate, the imported certificate will overwrite it. 18.7 Assigning policies for tokens When you assign policies you can specify other token options. These relate to: PINs Logon mode Defining token PINs for POA autologon What happens when the status of the token is no longer recognized Unblocking the token The middleware to be used (PKCS#11 module) 18.8 Using tokens to log on at the Power-on Authentication To log on at the Power-on Authentication using a token, proceed as follows: Prerequisite: Note that the USB support is activated in the BIOS. The token support must be initialized and the token issued for you. 1. Plug the token into the USB interface. 2. Switch on the PC and wait until the Power-on Authentication stops. 3. Enter the token PIN. You are logged on to SafeGuard Enterprise. 185 SafeGuard® Enterprise 5.50, Administrator help Logon mode at the Power-on Authentication There are two ways of logging on using a token. A combination of both logon methods is possible. Logging on with user ID/password Logging on with token When logging on with token/smartcard, you can either select the non-cryptographic method or the Kerberos (cryptographic) method. With Kerberos, Challenge/Response procedures are not possible, as there is no logon information available in the POA. The security officer specifies the method to be used for users and computers in a policy of type Authentication. 18.9 Enabling POA autologon with default token PINs With a policy distributed default token PIN automatic user logon may be achieved at the Poweron Authentication. This saves issuing each single token separately and enables users to automatically log on at the Power-on Authentication without any user interaction. When a token is used at logon and a default PIN is assigned to the computer, the user is passedthrough at the Power-on Authentication without having to enter any PIN. As a security officer you may set the specific PIN in a policy of type Authentication and assign it to different computers or computer groups, for example to all computers residing in the same location. To enable autologon with a default token PIN, proceed as follows: 1. In the SafeGuard Management Center, click Policies. 2. Select a policy of type Authentication. 3. Under Logon Options in Logon mode, select Token. 4. In PIN used for autologon with token, specify the default PIN to be used for autologon. PIN rules do not need to be observed in this case. Note: This setting is only available if you select Token as possible Logon Mode 5. In Pass-through to Windows set Disable pass-through to Windows. If you do not select this setting when a default PIN is specified, you will not be able to save the policy. If you want to enable the Pass-through to Windows option, you can later create another policy of type Authentication with this option enabled and assign it to the same computer group, so that the RSOP finally has both policies active. 186 SafeGuard® Enterprise 5.50, Administrator help 6. Optionally specify further token settings. 7. Save your settings and assign the policy to the relevant computers or computer groups. If the autologon on the endpoint computer has been successful, Windows will be started. If the autologon on the endpoint computer has failed, the user will be prompted to enter the token PIN at the Power-on Authentication. 18.10 Initializing, changing and blocking PINs If you are a Security Officer, you can change both the user PIN and the SO PIN, and also force the user PIN to be changed. This is usually required when a token is first issued. You can also initialize PINs, i.e. issue them as new and block them. You can use policies to specify other PIN options for the endpoint computer. Note: When changing a PIN, note that some token manufacturers specify their own PIN rules which may contradict SafeGuard Enterprise PIN rules. So it may not be possible to change a PIN in the way you want, even if it complies with the SafeGuard Enterprise PIN rules. So you should always refer to the token manufacturer's PIN rules. These are displayed in the Token area under Token Information in the Management Center. PINs are managed in the Management Center under Tokens. The token is plugged in and marked in the navigation window on the left. 18.10.1 Initializing user PIN Prerequisite: The SO PIN must be known. 1. To issue the user PIN anew, click the Initialize user PIN icon. Enter the SO PIN. 2. Enter the new user PIN, repeat the entry and confirm with OK. The user PIN is initialized. 18.10.2 Changing an SO PIN Prerequisite: The previous SO PIN must be known. 1. To change the SO PIN, click the Change SO PIN icon in the SafeGuard Management Center toolbar. 2. Enter the old SO PIN. 187 SafeGuard® Enterprise 5.50, Administrator help 3. Enter the new SO PIN, repeat the entry and confirm with OK. The SO PIN is initialized. 18.10.3 Changing a user PIN Prerequisite: The user PIN must be known. 1. To change the user PIN, click the Change user PIN icon in the SafeGuard Management Center toolbar. 2. Enter the old and the new user PIN, repeat the new user PIN, and confirm with OK. The user PIN is initialized. If you have changed the PIN for another user, inform them about the change. 18.10.4 Forcing PIN change To force a PIN change proceed as follows: 1. Click the Force PIN change icon in the SafeGuard Management Center toolbar. The next time the user logs on with the token, they will have to change their user PIN. 18.10.5 PIN history The PIN history can be deleted. To do this, click the Delete PIN history icon in the SafeGuard Management Center toolbar. 18.11 Managing tokens and smartcards In the Tokens area of the Management Center, the Security Officer can: get an overview of tokens and certificates that have been issued; filter overviews; block tokens for authentication; and read or delete the data on a token. 188 SafeGuard® Enterprise 5.50, Administrator help 18.11.1 Displaying token/smartcard information If you are a Security Officer you can display information about all or individual tokens that have been issued, and filter overviews. Prerequisite: The token must be plugged in. In the SafeGuard Management Center, click Tokens. Information about an individual token: Mark the token concerned under Token Slots. The manufacturer, type, serial number, hardware details and PIN rules are displayed under Token Information. You can also see which user the token is assigned to. Overview of tokens: Mark Issued Tokens. You can display all the tokens that have been issued or filter the overview by user. The token's serial number, the assigned users and the issue date are displayed. You can also see if the token is blocked. 189 SafeGuard® Enterprise 5.50, Administrator help 18.11.2 Reading token/smartcard information If you are a Security Officer you can use the user PIN issued for the token to see what data is on the token. Prerequisite: The token must be plugged in. The Security Officer must know the PIN. Or it must be initialized, see Initializing user PIN on page 187. In the SafeGuard Management Center, click Tokens. 1. On the left of the navigation area, under Token Slots, mark the token concerned and select the Logon Information & Certificates tab. 2. Click the Get user credentials icon and enter the user PIN for the token. The data on the token is displayed. 190 SafeGuard® Enterprise 5.50, Administrator help 18.11.3 Deleting token/smartcard information If you are a Security Officer you can delete the information that has been written on the token by SafeGuard Enterprise. Prerequisite: The token must be plugged in. In the SafeGuard Management Center, click Tokens. 1. Mark the token concerned under Token Slots on the left of the navigation area. 2. Click the Wipe token icon in the SafeGuard Management Center toolbar. 3. Enter the SO Pin that was assigned to the token and confirm with OK. All data managed by SafeGuard Enterprise is deleted. Certificates remain on the token. The user PIN is reset to 1234. Deleted tokens are thus automatically deleted from the list of issued tokens. 18.11.4 Blocking token or smartcard If you are a Security Officer you can block tokens. This is useful, e.g., if a token has been lost. In the SafeGuard Management Center, click Tokens. 1. Mark Issued Tokens on the left of the navigation area. 2. Mark the token to be blocked and click the Block token icon in the SafeGuard Management Center toolbar. The token is blocked for authentication and the assigned user can no longer use it to log on. The token can only be unblocked with the SO PIN. 191 SafeGuard® Enterprise 5.50, Administrator help 19 SafeGuard Data Exchange SafeGuard Data Exchange is used to encrypt data stored on removable media connected to a computer and to exchange these data with other users. All encryption and decryption processes run transparently and involve minimum user interaction. Only users who have the appropriate keys can read the contents of the encrypted data. All subsequent encryption processes run transparently. In central administration, you define how data on removable media are handled. As a security officer you define the specific settings in a policy of the type Device Protection with Device protection target: Removable Media. For SafeGuard Data Exchange file based encryption has to be used. Group Keys To exchange encrypted data between users, SafeGuard Enterprise group keys have to be used. If the group key is in the users’ key rings, the users get full transparent access to removable media connected to their computers. On computers without SafeGuard Enterprise accessing the encrypted data on removable media is not possible, except the central defined domain/group key which can be used together with the media passphrase. Note: To use/share encrypted data on removable media also on/with computers/users that do not have SafeGuard Enterprise, SafeGuard Portable can be used. SafeGuard Portable requires the usage of local keys or a media passphrase. Local Keys SafeGuard Data Exchange supports encryption using local keys. Local keys are created on the computers and can be used to encrypt data on removable media. They are created by entering a passphrase and are backed up in the SafeGuard Enterprise database. Note: By default a user is allowed to create local keys. In case users should not be able to do so you have to disable this option explicitly. This has to be done in a policy of the type Device Protection with Device protection target: Local Storage Devices (General Settings > User is allowed to create local key: No). If local keys are used to encrypt files on removable media, these files can be decrypted using SafeGuard Portable on a computer without SafeGuard Data Exchange. When the files are opened with SafeGuard Portable the user is prompted to enter the passphrase that was specified when the key was created. If the user knows the passphrase they can open the file. 192 SafeGuard® Enterprise 5.50, Administrator help Using SafeGuard Portable every user who knows the passphrase can get access to an encrypted file on removable media. This way it is also possible to share encrypted data with partners, who do not have SafeGuard Enterprise. They only need to be provided with SafeGuard Portable and the passphrase for the files they should have access to. If different local keys are used to encrypt files on removable media, you can even restrict access to files. For example: You encrypt the files on a USB stick using a key with passphrase my_localkey and encrypt a single file named ForMyPartner.doc using the passphrase partner_localkey. If you give the USB stick to a partner and provide them with the passphrase partner_localkey, they will only have access to ForMyPartner.doc. Note: By default SafeGuard Portable is automatically copied to all removable media connected to the system. If you do not want SafeGuard Portable to be automatically copied to removable media, deactivate the Copy SG Portable to Removable Media option in a policy of the type Device Encryption. Media passphrase Additionally SafeGuard Data Exchange allows to specify that one single media passphrase for all removable media - except optical media - has to be created on the computers. The media passphrase provides access to the centrally defined domain/group key as well as to all used local keys in SafeGuard Portable. The user only has to enter one single passphrase and gets access to all encrypted files in SafeGuard Portable, regardless of the local key used for encryption. On every computer a unique Media Encryption Key for data encryption is automatically created for each device. This key is protected with the media passphrase and a centrally defined domain/ group key. On a computer with SafeGuard Data Exchange it is therefore not necessary to enter the media passphrase to access encrypted files on the removable media. Access is granted automatically if the appropriate key is part of the user’s key ring. The domain/group key to be used has to be specified under Defined key for encryption. Media passphrase functionality is available when the User may define a Media Passphrase for devices option is activated in a policy of the type Device Protection. When this setting becomes active on the computer, the user is automatically prompted to enter a media passphrase, when he connects removable media for the first time. The media passphrase is valid on every computer the user is allowed to log on to. The user may also change the media passphrase and it will be synchronized automatically when the passphrase known on the computer and the media passphrase of the removable media are out of sync. In case the user forgets the media passphrase, it can be recovered by the user without any need of a Help Desk. Note: To enable the media passphrase activate the User may define a Media Passphrase for devices option in a policy of the type Device Encryption. 193 SafeGuard® Enterprise 5.50, Administrator help Media passphrase and unmanaged endpoint computers On an unmanaged endpoint computer, i.e. the computers operating in standalone mode, without an activated media passphrase feature no keys are available after installation has been completed since unmanaged endpoint computers only use local keys. Before encryption can be used, the user has to create a key. In case the media passphrase feature is activated in a removable media policy for these computers, the media encryption key is created automatically on the computer and can be used for encryption immediately after installation has been completed. It is available as a predefined key in the users key ring and is displayed as <user name> in dialogs for key selection. If available, the media encryption keys will also be used for all initial encryption tasks. 19.1 Best practice This section describes some typical use cases for SafeGuard Enterprise and how to implement them by creating the appropriate policies. Bob and Alice are two employees of the same company and have SafeGuard Data Exchange installed, Joe is an external partner and does not have SafeGuard Enterprise installed on his PC. 19.1.1 Company internal use only Bob wants to share encrypted data on removable media with Alice. Both belong to the same group and therefore have the appropriate group key in their SafeGuard Enterprise key ring. As they are using the group key they can access the encrypted files transparently without the need to enter a passphrase. You have to specify the settings in a policy of the type Device Protection\Removable Media: Media Encryption Mode: File based Key to be used for encryption: Defined key on list Defined key on list: <group/domain key > (e.g. group_users_Bob_Alice@DC=...) to ensure that both share the same key 194 SafeGuard® Enterprise 5.50, Administrator help If company policies additionally define that all files on removable media have to be encrypted in any situation, add the following settings: Initial encryption of all files: Yes Ensures that files on removable media are encrypted as soon as the media is connected to the system for the first time. User may cancel initial encryption: No The user cannot cancel initial encryption, for example to postpone it. User is allowed to access encrypted files: No If plain files on removable media are detected, access to them will be denied. User may decrypt files: No The user is not permitted to decrypt files on removable media. Copy SG Portable to Removable Media: No. As long as data on removable media are shared within the workgroup SafeGuard Portable is not necessary. Also, SafeGuard Portable would allow to decrypt files on computers without SafeGuard Enterprise. The users can share data just by exchanging their devices. When they connect the devices to their computers they have transparent access to encrypted files. Note: This use case can be fulfilled by using SafeGuard Enterprise Device Encryption where the whole removable device is sector-based encrypted. 19.1.2 Home office or personal use on 3rd party PCs Home office: Bob wants to use his encrypted removable media on his home PC, where SafeGuard Enterprise is not installed. On his home PC Bob decrypts files using SafeGuard Portable. By defining one media passphrase for all of Bob’s removable media, he only has to open SafeGuard Portable and enter the media passphrase. Afterwards Bob has transparent access to all encrypted files regardless of the key used to encrypt them. Personal use on 3rd party PCs: Bob plugs in the removable device on Joe's (external partner) computer and enters the media passphrase to get access to the encrypted files stored on the device. Bob can now copy the files either encrypted or unencrypted - to Joe's computer. 195 SafeGuard® Enterprise 5.50, Administrator help Behavior on endpoint computer Bob plugs in the removable device for the first time. The Media Encryption Key, which is unique for each device, is created automatically. Bob is prompted to enter the media passphrase for offline use via SG Portable. There is no need to bother the user with knowledge about keys to be used or the key ring. The Media Encryption Key will always be used for data encryption without any user interaction. The Media Encryption Key is not even visible to the user but only the centrally defined group/ domain key. Bob and Alice within the same group or domain have transparent access since they share the same group/domain key. If Bob wants to access encrypted files on a removable device on a computer without SafeGuard Data Exchange, he can use the media passphrase within SafeGuard Portable. You have to specify the settings in a policy of the type Device Protection\Removable Media: Media Encryption Mode: File based Key to be used for encryption: Defined key on list Defined key on list: <group/domain key > (e.g. group_users_Bob_Alice@DC=...) to ensure that both share the same key. User may define (media) passphrase: Yes The user defines one media passphrase on their computer which is valid for all their removable media. Copy SafeGuard Portable to removable media: Yes SafeGuard Portable gives the user access to all encrypted files on the removable media by entering a single media passphrase on the system without SafeGuard Data Exchange. If the company policies additionally define that all files on removable media have to be encrypted in any situation, add the following settings: Initial encryption of all files: Yes Ensures that files on removable media are encrypted as soon as the media is connected to the system for the first time. User may cancel initial encryption: No The user cannot cancel initial encryption, for example to postpone it. User is allowed to access encrypted files: No If plain files on removable media are detected, access to them will be denied. 196 SafeGuard® Enterprise 5.50, Administrator help User may decrypt files: No The user is not permitted to decrypt files on removable media. At work, Bob as well as Alice have transparent access to encrypted files on removable media. At home or on 3rd party PCs, they can use SafeGuard Portable to open encrypted files. The users only have to present the media passphrase and have access to all encrypted files. This is a simple but effective way to encrypt data on every removable media. The goal of this configuration is to reduce user interaction to a minimum but to encrypt each and every file on removable media as well as give the users access to the encrypted files in offline mode. The user is not permitted to decrypt files on removable media. Note: In this configuration users are not allowed to create local keys since it is not necessary for that use case. This has to be specified in a policy of the type Device Protection with Device protection target: Local Storage Devices (General Settings > User is allowed to create local key: No). Copy SafeGuard Portable to Removable Media: No. As long as data on removable media are shared in the work group SafeGuard Portable is not necessary. Also SafeGuard Portable would allow to decrypt files without SafeGuard Enterprise. At work the user has transparent access to encrypted files on removable media. At home they use SafeGuard Portable to open encrypted files. The user only has to present the media passphrase and has access to all encrypted files, regardless of the key used for encrypting them. 19.1.3 Share removable media with external party Bob wants to hand out an encrypted device to Joe (external party) who does not have SG Data Exchange installed and therefore has to use SG Portable. In assumption that Bob does not want to give Joe access to all encrypted files on the removable media he can create a local key and encrypt the files with this local key. Joe can now use SG Portable and open the encrypted files via the passphrase of the local key, whereas Bob still can use the media passphrase to access any encrypted file on the removable device. Behavior on computer 197 Bob plugs in the removable device for the first time. The Media Encryption Key, which is unique for each device, is created automatically. Bob is prompted to enter the media passphrase for offline use. The Media Encryption Key gets used for data encryption without any user interaction, but… Bob can now create or select a local key (e.g. called JoeKey) for the encryption of specific files that shall be exchanged with Joe. Bob and Alice within the same group or domain have transparent access since they share the same group/domain key SafeGuard® Enterprise 5.50, Administrator help If Bob wants to access encrypted files on a removable device on a computer without SafeGuard Data Exchange, he can use the media passphrase within SafeGuard Portable. Joe can access the specific files by entering the passphrase of the JoeKey without having access to the whole removable media. You have to specify the settings in a policy of the type Device Protection\Removable Media: Media Encryption Mode: File based Key to be used for encryption: Any key in user key ring Allows the user to choose different keys for encrypting files on their removable media. Defined key for encryption: <group/domain key > (e.g. group_users_Bob_Alice@DC=...)

User may decrypt files: No The user is not permitted to decrypt files on removable media. At work Bob as well as Alice have transparent access to encrypted files on removable media. At home they can use SafeGuard Portable to open encrypted files by entering the media passphrase. If Bob or Alice wants to hand out the removable media to a 3rd party PC that does not have SafeGuard Data Exchange installed, they can use local keys to ensure that the external party can access only some specific files. This is an advanced configuration, which means more interaction for the user by allowing them to create local keys on their computer. Note: A prerequisite for this example is, that the user is allowed to create local keys. (default setting in SafeGuard Enterprise). 198 SafeGuard® Enterprise 5.50, Administrator help 20 Power-on Authentication (POA) SafeGuard Enterprise identifies the user even before the operating system starts up. To do this, SafeGuard Enterprise's own system core starts before this. It is protected against modifications and is saved, hidden, on the hard disk. Only when the user has been properly authenticated in the POA, the actual operating system (Windows) is started from the encrypted partition and the user is logged on automatically to Windows later. The procedure is the same when the computer is switched back on from hibernation (Suspend to Disk). The SafeGuard Enterprise Power-on Authentication has benefits such as: a graphical user interface with mouse support and draggable windows, so it is easy to read and use. a graphical layout which, following guidelines, can be adapted by corporate computers (background image, logon image, welcome message, etc.). support for many card readers and smartcards support for Windows user accounts and passwords even pre-boot, no more separate credentials which the user has to remember support for Unicode and therefore also foreign language passwords and user interfaces 20.1 Logging on SafeGuard Enterprise works with certificate-based logging on. So users need keys and certificates to successfully log on at the Power-on Authentication. However, user-specific key and certificates are only created after a successful Windows logon. I.e. only users who have successfully logged on to Windows can also be authenticated in the Power-on Authentication. 199 SafeGuard® Enterprise 5.50, Administrator help To clarify how a user logs on in SafeGuard Enterprise, a brief introduction follows. For a detailed description of the POA logon procedures, refer to the SafeGuard Enterprise User help. Note: Under Windows Vista users first have to press CTRL+ALT+DEL to start autologon and logon. The administrator can deactivate this setting in the MMC console in the group policy object editor under Windows Settings > Security Settings > Local Policies > Deactivate Security Options (Interactive logon: CTRL+ ALT+DEL not required). 20.1.1 SafeGuard Autologon When logging on for the first time, SafeGuard Enterprise Autologon appears after starting the endpoint computer. What happens? 1. An autouser is logged on. 2. The client is automatically registered on the SGN server. 3. The machine key is sent to the SGN server and stored in the SGN database. 4. Machine policies are sent to the endpoint computer. 20.1.2 Windows logon The Windows logon dialog appears. The user logs on. What happens? 1. User ID and the encrypted password are sent to the server. 2. User policies, certificates and keys are created and sent to the endpoint computer. 3. The POA is activated. 20.1.3 POA logon When the endpoint computer restarts, the POA appears. What happens? 1. Certificates and keys are available for the user and they can log on at the POA. 2. All the data is securely encrypted with the user's public RSA key. 3. Any other users who want to log on must first be imported to the POA. 200 SafeGuard® Enterprise 5.50, Administrator help 20.1.4 Logon delay On a SafeGuard Enterprise protected computer, a logon delay applies if a user provides incorrect credentials during authentication at Windows or at the Power-on Authentication. With every failed logon attempt the delay is increased. After a failed logon a dialog is shown to display the remaining delay time. Note: If a user enters an incorrect PIN during token logon, there will be no delay. You can specify the number of logon attempts allowed in a policy of the type Authentication using option Maximum no. of failed logons. 20.1.5 Machine lock In a policy of the type Authentication you can also specify that the computer is to be locked after the set number of failed logon attempts by setting option Lock Machine to Yes. For unlocking their computer, users have to initiate a Challenge/Response procedure. 20.2 Importing further users The first user to log on in Windows is automatically registered in the POA. At first, no other Windows user can log on to the POA. Further users must be imported with the assistance of the first user. For a detailed description of importing further users, refer to the SafeGuard Enterprise User help. A policy setting specifies who is permitted to import a new user. You can find this policy in the Management Center under Policy items Type: Computer-specific Field: Importing new users allowed for Default setting: owner 201 SafeGuard® Enterprise 5.50, Administrator help An endpoint computer's owner is specified in the Management Center under Users & Computers Mark <endpoint computer name> Users tab Note: For unmanaged endpoint computers, i.e., endpoint computers operating in standalone mode, SafeGuard Enterprise offers POA access accounts. POA access accounts are predefined local accounts that enable users to log on (POA logon) to endpoint computers after the Power-on Authentication has been activated to perform administrative tasks. The accounts are defined in the Users and Computers area of the SafeGuard Management Center (user ID and password) and assigned to the endpoint computers via POA access groups included in configuration packages. Note: For detailed information on POA access accounts, see POA access accounts for POA logon at unmanaged endpoint computers, page 4 20.3 Configuring the Power-on Authentication The POA dialog consists of these components: Logon image Dialog text Language of the keyboard layout You can alter the look of the POA dialog to suit your preferences using, e.g., policy settings in the SafeGuard Management Center. 202 SafeGuard® Enterprise 5.50, Administrator help 20.3.1 Background and logon image By default the background and logon images that appear in the POA are in SafeGuard design. However, different images can be shown, e.g. the company’s logo. Background and logon images are defined via a policy of the type General Settings. For usage in SafeGuard Enterprise, background and logon images must fulfill certain requirements: Background image Maximum file size for all background images: 500 KB SafeGuard Enterprise supports two variants for background images: 1024x768 (VESA mode) Colors: no restrictions Option in policy type General Settings: Background image in POA 640x480 (VGA mode) Colors: 16 Option in policy type General Settings: Background image in POA (low resolution) Logon image Maximum file size for all logon images: 100 KB SafeGuard Enterprise supports two variants for logon images: 413x140 Colors: no restrictions Option in policy type General Settings: Logon image in POA 413x140 Colors: 16 Option in policy type General Settings: Logon image in POA (low resolution) Images, information texts and lists have to be created as files (BMP, PNG, JPG or text files) first and can then be registered in the navigation window. 203 SafeGuard® Enterprise 5.50, Administrator help 20.3.1.1 Registering images To register images do the following: 1. In the Policies navigation area right-click Images and select New > Image. 2. Enter a name for the image in the Image Name field. 3. Click [...] to select the previously created image. 4. Click OK. The new image will be shown as a subnode of Images in the policy navigation area. If you select the image, it will be displayed in action area. The image can now be selected when creating policies. Proceed as described to register further images. All registered images will be shown as subnodes. Note: Using the Modify Image button you can exchange the picture assigned. Upon clicking this button a dialog is displayed for selecting a different image. 20.3.2 User defined information text in the POA You can customize the POA to display the following user-defined information texts: Information text to be displayed upon initiating a Challenge/Response procedure for logon recovery (e.g.: “Please contact Support Desk on telephone number 01234-56789.”) Option in policy type General Settings: Information text Legal notices to be displayed after logging on to the POA Option in policy type Specific Machine Settings: Legal notice text Text for additional information to be displayed after logging on to the POA Option in policy type Specific Machine Settings: Additional information text 20.3.2.1 Registering information texts The text files containing the required information have to be created prior to registering them in the SafeGuard Management Center. The maximum files size for information texts is 50 KB. SafeGuard Enterprise only uses Unicode UTF-16 coded texts. If you do not create the text files in this format, they will be automatically converted upon registration. In case of a conversion process, a message will be displayed indicating that the file is being converted. 204 SafeGuard® Enterprise 5.50, Administrator help To register information texts: 1. In the Policies navigation area right-click Information text and select New > Text. 2. Enter a name for the text to be displayed in the Text item name field. 3. Click [...] to select the previously created text file. If the file needs to be converted, a message will be displayed. 4. Click OK. The new text item is displayed as a subnode below Information text in the policy navigation area. If you select a text item, its contents will be displayed in the window on the right-hand side. The text item can now be selected when creating policies. Proceed as described to register further text items. All registered text items will be shown as subnodes. Note: Using the Modify Text button, you can add new text to existing text. When clicking this button a dialog is displayed for selecting another text file. The text contained in this file will be appended at the end of the existing text. 20.3.3 Language for POA dialog text After installation of the SafeGuard Enterprise encryption software, the POA dialog text is displayed in the default language which is set in Windows' Regions and Language Options on the endpoint computer when installing SafeGuard Enterprise. After installation, the language in which the POA dialog text is displayed can only be changed via a policy defined in the SafeGuard Management Center. Changing the default language under Windows does not affect the language of the POA dialog text. The language for the POA dialog text is defined via a policy of the type General Settings (option Language used on Client). 205 SafeGuard® Enterprise 5.50, Administrator help 20.3.4 Keyboard Layout Almost every country has its own keyboard layout, i.e. the keys are assigned differently. The keyboard layout in the POA is significant when entering user names, passwords and response code. As the default, SafeGuard Enterprise adopts the keyboard layout in the POA which is set in Windows' Regional and Language Options for the Windows default user at the time SafeGuard Enterprise is installed. If “German” is the keyboard layout set under Windows, the German keyboard layout will be used in the POA. The language of the keyboard layout being used is displayed in the POA, e.g. “EN” for English. Apart from the default keyboard layout, the US keyboard layout (English) can also be used. There are certain exceptions: The keyboard layout is, indeed, supported, but the absence of a font (e.g. for Bulgarian) means that only special characters are displayed in the User Name field. No specific keyboard layout is available (e.g. Dominican Republic). In these cases, the POA falls back on the original keyboard layout. For the Dominican Republic, this is “Spanish”. Note: All the unsupported keyboard layouts use the US keyboard layout as the default. This also means that the only characters that are recognized and can be keyed in are those which are supported in the US keyboard layout. So users can only log on to the POA if their user name and password is composed of characters that are supported by the US keyboard layout or the respective fallback keyboard of their language. 20.3.4.1 Virtual keyboard SafeGuard Enterprise provides a virtual keyboard which users can show/hide at the POA and click the on-screen keys to enter credentials etc. As a security officer you can activate/deactivate the display of the virtual keyboard in a policy of the type Specific Machine Settings using the Virtual Keyboard option. Virtual keyboard support must be activated/deactivated via a policy setting. The virtual keyboard will support different layouts and it will be possible to change the layout using the same options as for changing the POA keyboard layout. 206 SafeGuard® Enterprise 5.50, Administrator help 20.3.4.2 Changing the keyboard layout The Power-on Authentication keyboard layout including the virtual keyboard layout can be changed retrospectively. To change the language of the keyboard layout, do as follows: 1. Select Start > Control Panel > Regional and Language Options > Advanced. 2. In the Regional Options tab, select the required language. 3. In the Advanced tab activate option Apply all settings to the current user account and to the default user profile under Default user account settings. 4. Confirm your settings with OK. The POA remembers the keyboard layout used for the last successful logon and automatically enables it for the next logon. This requires two reboots of the endpoint computer. If the remembered keyboard layout is deactivated via Regional and Language Options, it is still maintained up to the point where the user selects a different one. Note: Additionally, it is required to change the language of the keyboard layout for non-Unicode programs. If the language you want is not available on the system, Windows may prompt you to install it. After you have done so you need to reboot the computer twice so that, first, the new keyboard layout can be read in by the Power-on Authentication and, secondly, the POA can set the new layout. You can change the required keyboard layout for the Power-on Authentication using the mouse or keyboard (Alt+Shift). You can see which languages are installed and available on the system via Start > Run > regedit > HKEY_USERS\.DEFAULT\Keyboard Layout\Preload. 207 SafeGuard® Enterprise 5.50, Administrator help 20.4 Supported Hotkeys in the Power-on Authentication Certain hardware settings and functionalities can lead to problems when booting endpoint computers, causing the system to hang. The Power-on Authentication supports a number of hotkeys for modifying these hardware settings and deactivating functionalities. Furthermore, grey and black lists covering functions known to cause problems are integrated in the .msi file installed on the computer. We recommend you install an updated version of the POA configuration file prior to any significant deployment of SafeGuard Enterprise. The file is updated on a monthly basis and made available to download from here: ftp://POACFG:[email protected] You can customize this file to reflect the hardware of a particular environment. Note: When defining a customized file, only this will be used instead of the one integrated in the .msi file. Only when no POA configuration file is defined or found, the default file will be applied. To install the POA configuration file, enter the following command: MSIEXEC /i <Client MSI package> POACFG=<path of the POA configuration file> For further information see the knowledgebase: http://www.sophos.com/support/ knowledgebase/article/65700.html. The following hotkeys are supported in the POA: Shift F3 = USB Legacy Support (on/off) Shift F4 = VESA graphic mode (off/on) Shift F5 = USB 1.x and 2.0 support (off/on) Shift F6 = ATA Controller (off/on) Shift F7 = USB 2.0 support only (off/on) USB 1.x support remains as set by Shift F5.

However, please be aware that if the computer uses a USB keyboard or USB mouse, they might be disabled when pressing Shift F5. 2. If no USB support is active, the POA tries to use BIOS SMM instead of backing up and restoring the USB controller. The Legacy mode may work in this scenario. 3. Legacy support is active, USB is active. The POA tries to backup and restore the USB controller. The system might hang depending on the BIOS version used. You can specify changes that can be carried out using hotkeys when installing SafeGuard Enterprise encryption software using a .mst file. This is done using the appropriate call in combination with msiexec.

For details on activating the Rescue and Recovery authentication please refer to the Lenovo Rescue and Recovery documentation. 210 SafeGuard® Enterprise 5.50, Administrator help 21 Recovery options For recovery, SafeGuard Enterprise offers different options that are tailored to different scenarios: Logon recovery via Local Self Help Local Self Help enables users who have forgotten their password to log on to their computers without the assistance of a help desk. Even in situations where neither telephone nor network connections are available (for example aboard an aircraft), users can regain access to their computers. To log on, they answer a predefined number of questions in the Power-on Authentication. Local Self Help reduces the number of calls concerning logon recovery, thus freeing the help desk staff from routine tasks and allowing them to concentrate on more complex support requests. For detailed information see Recovery via Local Self Help, page 212. Recovery via Challenge/Response The Challenge/Response recovery mechanism is a secure and efficient recovery system that helps users who cannot log on to their computers or access encrypted data. During the Challenge/Response procedure, the user provides a challenge code generated on the endpoint computer to the help desk officer who in turn generates a response code that authorizes the user to perform a specific action on the computer. With recovery via Challenge/Response, SafeGuard Enterprise offers different workflows for typical recovery scenarios requiring help desk assistance. For detailed information see Recovery via Challenge/Response, page 218. System recovery SafeGuard Enterprise offers different methods and tools for recovery regarding crucial system components and SafeGuard Enterprise components, for example: Corrupted MBR SafeGuard Enterprise kernel problems Volume access problems Windows boot problems GINA problems For detailed information see System Recovery, page 245. 211 SafeGuard® Enterprise 5.50, Administrator help 22 Recovery via Local Self Help SafeGuard Enterprise offers Local Self Help for SafeGuard Enterprise protected computers to enable users who have forgotten their password to log on to their computers without the assistance of the help desk. With Local Self Help, users can, for example, regain access to their laptops in situations where neither telephone nor network connections are available and where they cannot use a Challenge/ Response procedure (for example aboard an aircraft). The user can log on to their computer by answering a predefined number of questions in the Power-on Authentication. As a security officer you can define the set of questions to be answered centrally and distribute it to the computer via a policy. We provide you with a predefined question theme as a template. You can use this question theme as is or modify it. In the relevant policy, you can also grant the users the right to define their own questions. For providing the initial answers and editing the questions, the Local Help Self Wizard is available on the endpoint computer after the function has been enabled by policy. For a detailed description of Local Self Help on the endpoint computer refer to the SafeGuard Enterprise User help, chapter Recovery via Local Self Help. Local Self Help reduces the number of calls concerning logon recovery, thus freeing the help desk staff from routine tasks and allowing them to concentrate on more complex support requests. 22.1 Defining Local Self Help settings via policy You define the settings for Local Self Help in a policy of the type General Settings under Logon Recovery - Enable Local Self Help. This is where you enable the function to be used on the endpoint computers and define further rights and parameters. 22.1.1 Enabling Local Self Help To activate Local Self Help for use on endpoint computers, select Yes in the Enable Local Self Help field. After the policy has become effective on the computers, this setting entitles the users to use Local Self Help for logon recovery. To be able to use Local Self Help, the users now have to activate this recovery method by answering a specified number from the set of questions received or by creating and answering their own questions - depending on permission. For this purpose, the Local Self Help Wizard will be available via the System Tray Icon in the Windows taskbar after receiving the policy and restarting the computer. 212 SafeGuard® Enterprise 5.50, Administrator help 22.1.2 Defining further settings Besides enabling Local Self Help you can define the following parameters for this function in a policy of the type General Settings: Minimal length of answers In this field, define the minimum length of the answers in characters.

Prior to specifying the text here, it has to be created and registered. Users can define their own questions There are the following possible scenarios for the definition of questions for Local Self Help: As a security officer you define the questions and distribute them to the users. The users are not permitted to define their own questions. As a security officer you define the questions and distribute them to the users. In addition, the users are permitted to define their own questions. When answering the minimum number of questions required for activating Local Self Help, the users can choose between predefined questions and their own questions or use a combination of both. You entitle the users to define their own questions. The users activate Local Self Help on their computers by defining and answering their own questions. To entitle users to define their own questions, select option Yes in the Users can define their own questions field. 22.2 Defining questions To be able to use Local Self Help on the endpoint computer, the user has to answer and save at least ten questions. To log on at the Power-on Authentication via Local Self Help, the user has to answer five questions randomly selected from these ten questions. If the user is not permitted to define their own questions, you therefore have to transfer at least ten predefined questions to the computer with the policy to enable the user to activate Local Self Help. For registering and editing Local Self Help questions you as a security officer need the right to Modify selfhelp questions. 213 SafeGuard® Enterprise 5.50, Administrator help 22.2.1 Using the template For Local Self Help a predefined question theme is available. By default, this question theme is available in German and English in the policy navigation area under Local Self Help questions. Optionally, the question theme is also available in French, Italian, Spanish, and Japanese. You can additionally import these language versions into the policy navigation area. Note: When entering answers in Japanese to activate Local Self Help on endpoint computers, users have to use Romaji (Roman) characters. Otherwise the answers will not match when users enter them in the Power-on Authentication. You can use the predefined question theme as is, edit it or delete it. If you leave the two language versions of the predefined question theme as is and enable Local Self Help via a policy of the type General Settings, the two predefined question themes will be transferred automatically to the endpoint computers with the policy. 22.3 Importing question themes Using the import procedure, you can import additional language versions of the predefined question theme or your own question lists created as .XML files.

There is no point in third parties eavesdropping on this procedure because the data they spy out cannot be used at any later point in time or on any other devices. The computer to be accessed does not need an online network connection. The Response Code Wizard for the Helpdesk also runs on an unmanaged computer without any SafeGuard Enterprise Server connection. There is noneed for a complex infrastructure. The user can start working again quickly. No encrypted data is lost only because the password has been forgotten. 23.2 Typical situations for requiring help desk assistance A user has forgotten the password for logging on and the computer has been locked. The Power-on Authentication local cache is partly damaged. A user is not available at the moment due to illness or vacation but the data on the computer must be accessible to a colleague. A user wants to access a volume encrypted with a key that is not available on the computer. SafeGuard Enterprise offers different recovery workflows for these typical scenarios enabling the users to access their computers again. 218 SafeGuard® Enterprise 5.50, Administrator help 23.3 Challenge/Response workflow The Challenge/Response procedure is based on two components: The endpoint computer on which the Challenge code will be generated. The SafeGuard Management Center where, as a help desk officer with sufficient rights, you will create a response code that will authorizes the user to perform the requested action on their computer. 1. On the endpoint computer, the user requests the challenge code. Depending on the recovery type, this is either requested in the Power-on Authentication or via the KeyRecovery Tool. A challenge code in form of an ASCII character string will be generated and displayed. 2. The user contacts the help desk and provides the necessary identification as well as the challenge code to the help desk. 3. The help desk launches the Recovery Wizard in the SafeGuard Management Center. 4. The help desk selects the appropriate recovery type, confirms the identification information and the challenge code and selects the required recovery action. A response code in form of an ASCII character string will be generated and displayed. 5. The help desk provides the user with the response code e.g. via phone or text message. 6. The user enters the response code. Depending on the recovery type, this is either done in the POA or via the KeyRecovery Tool. The user is then permitted to perform the authorized action, for example resetting the password and may resume working. 219 SafeGuard® Enterprise 5.50, Administrator help 23.4 User password change requirements As part of the SafeGuard Enterprise recovery process the user may be forced to change their Windows password. The following table provides details on when changing the password will be required. The first four columns show specific conditions which can occur during the Challenge/ Response procdure. The last column indicates whether the user is forced to change the Windows password based on the conditions indicated in the previous columns. Condition: C/R issued with user logon and show passwordoption Condition: C/R issued with user logon Condition: Domain controller available Condition: Show password option declined by user Result: User is forced to change Windows password Yes Yes Yes No No Yes Yes Yes Yes Yes Yes Yes No Yes No No Yes Yes n/a Yes No Yes No n/a No No No No n/a No 23.5 Launching the Recovery Wizard To be able to perform a recovery procedure, make sure you have the required rights and permissions. 1. Log on to the SafeGuard Management Center. 2. Click Tools > Recovery in the menu bar. The SafeGuard Recovery Wizard is started. You can select which type of recovery is requested. 220 SafeGuard® Enterprise 5.50, Administrator help 23.6 Recovery types Select which type of recovery you want to use. The following recovery types are provided: Challenge/Response for SafeGuard Enterprise Clients (managed) Challenge/Response for computers that are centrally managed by the SafeGuard Management Center. They are listed in the Users & Computers area in the SafeGuard Management Center. Challenge /Response using Virtual Clients Easy recovery for encrypted volumes can be achieved when using specific files called Virtual Clients in cases where Challenge/Response would usually not be supported, for example when the POA is corrupted. Challenge/Response for Sophos SafeGuard Clients (standalone) Challange/Response fo computers that are locally managed. They never have any connection to the SafeGuard Enterprise Server. For each of these computers a key recovery file is generated during configuration. It contains the defined machine key which is encrypted with the company certificate. If this recovery key file is available, e.g. on a memory stick or via a shared network path so that the help desk officer can access it, Challenge/Response for a standalone computer is supported. Note: Also see the logon recovery method Local Self Help that does not require any help desk assistance. 221 SafeGuard® Enterprise 5.50, Administrator help 222 SafeGuard® Enterprise 5.50, Administrator help 23.7 Recovery via Challenge/Response for SafeGuard Enterprise Clients SafeGuard Enterprise offers recovery for SafeGuard Enterprise protected endpoint computers registered in the database in various disaster scenarios, such as password recovery or accessing data by booting from external media. Challenge/Response is supported for both SafeGuard Enterprise native computers or BitLocker encrypted endpoint computers. During Challenge/Response it is dynamically determined which type of computer is in use and the recovery workflow is adjusted accordingly. 23.7.1 Recovery actions for SafeGuard Enterprise Clients The recovery workflow depends on which type of endpoint computer recovery is requested for. Note: For BitLocker encrypted computers the only recovery action is to recover the key used to encrypt a specific volume. No password recovery is provided. 23.7.1.1 Recovering the password at POA level One of the most common scenarios is that users have forgotten their password. By default SafeGuard Enterprise is installed with an activated Power-on Authentication (POA). The POA password for accessing the computer is the same as the Windows password. If the user has forgotten the password at POA level, the SafeGuard Enterprise helpdesk officer will generate a response for Booting SGN client with user logon, but without displaying the user password. However, in this case, after entering the response code the computer will boot into the operating system, so the user has to change the password at Windows level subject to the condition that the domain is accessible. The user can then log on to Windows as well as to the Power-on Authentication with the new password. Best practice for recovering the password at POA level Note: We recommend to primarily using the following methods when the user has forgotten their password to avoid that the password has to be centrally reset: Note: Use Local Self Help. With recovery via Local Self Help the user can have the current password displayed and may continue using this password without having to reset it and without any help desk assistance. For further information, see Recovery via Local Self Help on page 4. Note: When using Challenge/Response: We recommend avoiding centrally resetting the password in the Active Directory prior to the Challenge/Response procedure. Avoiding this will ensure that the password remains synchronized between Windows and SafeGuard Enterprise. Ensure that the Windows help desk is educated accordingly. 223 SafeGuard® Enterprise 5.50, Administrator help As a SafeGuard Enterprise help desk officer, generate a response for Booting SGN client with user logon with option Display user password. This is advantageous as the password then does not have to be reset in the Active Directory. The user may continue working with the old password and change it locally afterwards, if desired. 23.7.1.2 Displaying the user password SafeGuard Enterprise offers users to have their password displayed during Challenge/Response. This is advantageous as the password then does not have to be reset in the Active Directory. The option is only available if Booting SGN client with user logon is requested. 23.7.1.3 A different user needs to boot the SafeGuard Enterprise protected computer In this case the user who needs to access the computer will boot the computer and enter their user name. The user will then request a Challenge. The SafeGuard help desk will generate a Response of type Booting SGN client without user logon and Passthrough to Windows enabled. The user will be logged on and may use the computer. 23.7.1.4 Accessing data by booting from external media Challenge/Response can also be used to allow a computer to be booted from external media such as WinPE. To do so, the user has to select Continue Booting from: Floppy Disk/External Medium in the POA logon dialog and initiate the Challenge. When receiving the response the user can enter the credentials in the POA as usual and continue booting from external medium. The following requirements must be fulfilled to access an encrypted volume: The device to be used must contain the SafeGuard Enterprise filter driver. A detailed description on how to create such a driver CD can be found in our knowledge database: http://www.sophos.com/support/knowledgebase/article/108805.html. The user must boot from the external medium and must have the right to do so. This right can be granted to the user by defining a policy in the SafeGuard Management Center and assigning it to the computer: (policy type Authentication > Access: User may only boot from hard disk must be set to „No“). By default the right to boot from external media is not assigned. The endpoint computer must generally support booting from different media other than a fixed hard drive. Only volumes encrypted with the defined machine key can be accessed. This key encryption type can be defined in a device encryption policy in the SafeGuard Management Center and assigned to the computer. Please note that using external media such as a WinPE to access an encrypted drive will only partly allow access to the volume. 224 SafeGuard® Enterprise 5.50, Administrator help 23.7.1.5 Restoring the SafeGuard Enterprise policy cache This procedure is necessary, if the SafeGuard policy cache is damaged. The local cache stores all keys, policies, user certificates and audit files. By default, logon recovery is deactivated when the local cache is corrupted, i.e. it will be restored automatically from its backup. In this case, no Challenge/Response procedure is required for repairing the local cache. However, logon recovery can be activated by policy, if the local cache is to be repaired explicitly via a Challenge/Response procedure. In this case, the user is prompted automatically to initiate a Challenge/Response procedure, if the local cache is corrupted. 23.7.2 Response for SafeGuard Enterprise Clients To generate a response during Challenge/Response for a SafeGuard Enterprise Client, the name of the respective endpoint computer and the domain are required. Note: This name must always be the distinguished name of the computer. 1. In the Recovery type window, select SafeGuard Enterprise Client (managed). 2. Select the required domain from the list. 3. Enter the required computer name. There are several possibilities to do so: Select a name by clicking [...] in the Computer information section of the Recovery type dialog.

Enter the computer name directly in distinguished name format, for example: CN=Desktop1,OU=Development,OU=Headquarter,DC=Sophos,DC=edu 4. Click Next. The program then dynamically determines if a native SafeGuard Enterprise computer or BitLocker encrypted computer is in use and adjusts the recovery workflow accordingly. In case of a native SafeGuard Enterprise computer the next step requires the selection of the user information. 225 SafeGuard® Enterprise 5.50, Administrator help After checking the database for the respective computer, the corresponding user name and domain is required for recovery of a SafeGuard Enterprise Client. 1. Select the required domain of the user. 2. Enter the required user name. There are several possibilities to do so: Select the user name by clicking [...] in the User information section of the Logon recovery dialog. Afterwards, click Find now. A list of users is displayed. Select the required name and click OK. The name is now displayed in the Recovery type window below Domain. Enter the name of the user directly. Make sure the name is spelled correctly. 3. Click Next. A window is displayed where you can enter the challenge code. 4. Enter the challenge code the user has passed on to you and click Next. The challenge code is verified. If the code has been entered incorrectly, Invalid is displayed below the block containing the error. 226 SafeGuard® Enterprise 5.50, Administrator help 5. If the challenge code has been entered correctly, the recovery action requested by the SafeGuard Enterprise Client as well as the possible recovery actions on the client are displayed. The possible actions for response depend on the actions requested on the client side when calling the challenge. For example, if Crypto token requested is required on the client side, the available actions for response are Boot SGN client with user logon and Boot SGN client without user logon. 6. Select the action the user needs to perform. 227 SafeGuard® Enterprise 5.50, Administrator help 7. If Booting SGN client with user logon has been selected as response action, you may additionally select Show user password to have the password displayed on the target computer. 8. Click Next. 9. A response code is generated. Read the response code to the user. A spelling aid is provided. You can also copy the response code to the clipboard. The user can then enter the response code on the endpoint computer and perform the authorized action. 228 SafeGuard® Enterprise 5.50, Administrator help 23.8 Response for BitLocker encrypted SafeGuard Enterprise Clients For BitLocker encrypted computers a volume that cannot be accessed any more may be recovered. In order to perform a response during Challenge/Response for a SafeGuard Enterprise Client, the name of the respective endpoint computer and the domain are required. Note: This name must always be the distinguished name of the computer. 1. In the Recovery type window select SafeGuard Enterprise Client. 2. Select the required domain form the list. 3. Enter the required computer name. There are several possibilities to do so: Select a name by clicking [...] in the Computer information section of the Recovery type dialog. Afterwards, click Find Now. A list of computers is displayed. Select the required computer and click OK. The computer name is then displayed in the Recovery type window below Domain. Enter the short name of the computer. When clicking Next, the database is searched for this name and if found, the distinguished computer name is displayed. Enter the computer name directly in distinguished name format, for example: CN=Desktop1,OU=Development,OU=Headquarter,DC=Utimaco,DC=edu 4. Click Next. The program then dynamically determines if a native SafeGuard Enterprise computer or BitLocker encrypted computer is in use and adjusts the recovery workflow accordingly. In case of a BitLocker encrypted computer the next step requires the selection of the required volume. After checking the database for the respective computer, the required volume is needed for recovery of a BitLocker encrypted endpoint computer. 1. Select the volume to be accessed from the list and click Next. 2. The Recovery Wizard then displays the corresponding 48-digit recovery key. 3. Read this key to the user. The user can then enter the key to recover the BitLocker encrypted volume on the endpoint computer. 229 SafeGuard® Enterprise 5.50, Administrator help 230 SafeGuard® Enterprise 5.50, Administrator help 23.9 Recovery via Challenge/Response using Virtual Clients With Virtual Client recovery SafeGuard Enterprise offers recovery of encrypted volumes even in complex disaster situations, e.g.when the POA is corupted. It can be applied to managed clients as well as to standalone computers. Note: Virtual Client recovery should only be used to resolve complex disaster situations. If, for instance, only a key is missing to recover a volume, the best way to recover the volume would simply be to assign the missing key to the respective user’s key ring. 23.9.1 Recovery workflow using Virtual Clients To access the encrypted computer, the following general workflow applies: 1. Obtain the SafeGuard Enterprise recovery disk from technical support. 2. The help desk may download the Windows PE recovery disk with the latest SafeGuard Enterprise filter drivers from the Sophos support site.

As a result of the successful decryption you can read, write and copy data from and/or to the respective drive. 240 SafeGuard® Enterprise 5.50, Administrator help 23.10 Challenge/Response for Sophos SafeGuard Clients (standalone) SafeGuard Enterprise also provides Challenge/Response for unmanaged computers (Sophos SafeGuard Clients). They never have any connection to the SafeGuard Enterprise Server, not even temporarily. They operate in standalone mode. As they are not registered in the SafeGuard Enterprise database no information on their identification needed for a Challenge/Response is available. For these computers, SafeGuard Enterprise provides Challenge/Response e.g. when the user has forgotten their password or entered the password incorrectly too often. Recovery information needed for a Challenge/Response is in this case based on the key recovery file. On each endpoint computer this key recovery file is generated during deployment of the SafeGuard Enterprise encryption software. If this key recovery file is accessible to the help desk, e.g. via a shared network path, Challenge/ Response for a SafeGuard Enterprise protected computer may be provided. To facilitate searching and grouping of the recovery files the files will carry the name of the computer: computername.GUID.xml in their file names. This allows for wild card search with asterisks (*), for example: *.GUID.xml. Note: When a computer is renamed , it will not be renamed accordingly in the computer’s local cache. The local cache stores all keys, policies, user certificates and audit files. The new computer name therefore has to be removed from the local cache so that only the previous name will remain, even if a computer is renamed under Windows. 23.10.1 Recovery actions for Sophos SafeGuard Clients (standalone) Challenge/Response for an endpoint computer can be initiated in the following situations: The user has entered the password incorrectly too often. The user has forgotten the password. A corrupted cache needs to be repaired. For an unmanaged computer no user key is available in the database. Therefore, the only recovery action possible in a Challenge/Response session is Booting SGN client without user logon. The Challenge/Response procedure will enable the computer to boot through Power-on Authentication. The user will then be able to log on to Windows. 241 SafeGuard® Enterprise 5.50, Administrator help Potential recovery use cases: The user has entered the password incorrectly too often at POA level and the computer is locked. The computer is locked, and the user is prompted to initiate a Challenge/Response procedure to unlock the computer. As in this case resetting the password is not needed because the user still remembers the current password, Challenge/Response procedure will enable the computer to boot through Power-on Authentication. The user can then enter the correct password at Windows level and use the computer again. The user has forgotten the password Note: We recommend to primarily use Local Self Help to recover a forgotten password. With recovery via Local Self Help the user can have the current password displayed in a confidential way in the Power-on Authentication and may continue using it. This will avoid that the password has to be reset at all and will also avoid help desk assistance. For further information, see Recovery via Local Self Help, page 4. When recovering a forgotten password via Challenge/Response a password reset is required. 1. The Challenge/Response procedure will enable the computer to boot through Power-on Authentication. 2. In the Windows logon dialog, the user does not know the correct password either and therefore needs to change it at Windows level. This requires further recovery actions outside the scope of SafeGuard Enterprise, via standard Windows means. Note: We recommend avoiding centrally resetting the password prior to the Challenge/Response procedure. Avoiding this will ensure that the password remains synchronized between Windows and SafeGuard Enterprise. Ensure that the Windows help desk is educated accordingly. 3. We recommend using the following methods to reset the password at Windows level. Via a service or administrator account available on the endpoint computer with the required Windows rights. Via a Windows password reset disk on the endpoint computer. As a help desk officer you may inform the user which procedure should be used and either provide the the additional Windows credentials or the required disk. 4. The user enters the new password at Windows level that the help desk has provided. The user then changes this password immediately to a value only known to the user. 242 SafeGuard® Enterprise 5.50, Administrator help 5. SafeGuard Enterprise detects that the newly chosen password does not match the current SafeGuard Enterprise password used in the POA. The user is therefore prompted to enter the old SafeGuard Enterprise password and, since the user has forgotten this password, needs to click Cancel. 6. In SafeGuard Enterprise, the definition of a new password without providing the old one requires a new certificate. The user has to confirm this procedure. 7. A new user certificate will be created based on the newly chosen Windows password. This enables the user to log on to the computer again and to log on at the Power-on Authentication with the new password. Note: Keys for SafeGuard Data Exchange Note: When the user has forgotten the Windows password and has to enter a new one, a new user certificate is created as well. Therefore, the user will not be able to use the keys already created for SafeGuard Data Exchange any longer. To be able to continue using the already generated user keys for SafeGuard Data Exchanges the user has to remember the SafeGuard Data Exchange passphrases to reactivate these keys. The local cache needs to be repaired The local cache stores all keys, policies, user certificates and audit files. By default, logon recovery is deactivated when the local cache is corrupted, i.e. it will be restored automatically from its backup. In this case, no Challenge/Response procedure is required for repairing the local cache. However, logon recovery can be activated by policy, if the local cache is to be repaired explicitly via a Challenge/Response procedure. In this case, the user is prompted automatically to initiate a Challenge/Response procedure, if the local cache is corrupted. 23.10.2 Generating a response for unmanaged computers using the key recovery file Note: The key recovery file generated during installation of the SafeGuard Enterprise encryption software needs to be stored in a location a help desk officer is able to access and the name of the file must be known. To generate a response, do the following: 1. In the SafeGuard Management Center, select Tools > Recovery from the menu bar to open the Recovery Wizard. 2. In Recovery type, select Shophos SafeGuard Client (standalone). 243 SafeGuard® Enterprise 5.50, Administrator help 3. Locate the required key recovery file by clicking Browse. For better identification, the recovery files carry the name of the computer: computername.GUID.xml. 4. Enter the challenge code the user has passed on to you and click Next. The challenge code is verified. If the challenge code has been entered correctly, the recovery action requested by the computer as well as the possible recovery actions are displayed. If the code has been entered incorrectly, Invalid is displayed below the block containing the error. 5. Select the required action to be taken by the user and click Next. 6. A response code is generated. Communicate the response code to the user. A spelling aid is provided. You may also copy the response code to the clipboard. The user can enter the response code, perform the requested action and resume working. 244 SafeGuard® Enterprise 5.50, Administrator help 24 System Recovery SafeGuard Enterprise encrypts files and drives transparently. Boot drives can also be encrypted, so decryption functionalities such as code, encryption algorithms and encryption key must be available very early in the boot phase. Therefore encrypted information cannot be accessed if the crucial SafeGuard Enterprise modules are unavailable or do not work. The following sections cover possible error sources and recovery methods. 24.1 Recover data by booting from an external medium This recovery type can be applied when the user can still log on at the POA but cannot access the encrypted volume any more. In this case, access to the encrypted data can be regained by booting the computer via a Windows PE recovery disk customized for SafeGuard Enterprise. Prerequisites: The user booting from the external medium must have the right to do so. This right can either be configured in the SafeGuard Management Center within a policy of type Authentication (User may decrypt volume set to Yes) or can be obtained for a one-time use via a Challenge/ Response procedure. The computer must support booting from different media than the fixed hard drive. To regain access to encrypted data on the computer, do the following: 1. Obtain the SafeGuard Enterprise Windows PE disk from technical support. The help desk may download the Windows PE recovery disk with the latest Sophos SafeGuard filter drivers from the Sophos support site. For further information see the knowledgebase: http://www.sophos.com/support/knowledgebase/article/108805.html. 2. Log on at the Power-on Authentication with your credentials. 3. Insert the Windows PE recovery disk into the computer. 4. In the POA logon dialog under Continue booting from: select external medium.The computer is started. Access to the data stored on this partition is recovered. 245 SafeGuard® Enterprise 5.50, Administrator help 24.2 Corrupted MBR For resolving problems with a corrupted MBR SafeGuard Enterprise offers the tool BE_Restore.exe. For a detailed description on how to restore a corrupted MBR with this tool refer to the SafeGuard Tools Guide. 24.3 Code It is possible to access a hard disk with damaged kernel boot code as keys are stored separately from the kernel in the so-called KSA (Key Storage Area). By separating the kernel and the keys, this type of drive can be decrypted when hooked up to another computer. To do this, the user logging on to the other computer needs a key for the KSA of the unbootable partition on their key ring. In the worst case, the partition is only encrypted using the other computer's Boot_Key. In such a case, the Master Security Officer or the Recovery Officer must assign this Boot_Key to the user. For a detailed description of this procedure, see “Slaving” a hard disk, page 248. 24.4 Volumes SafeGuard Enterprise provides drive-based encryption. This includes saving encryption information consisting of the boot sector, primary and backup KSA and the original boot sector on each drive itself. As soon as one of the below units is damaged, the volume cannot be accessed any longer: either of the two Key Storage Areas (KSA) Original MBR 246 SafeGuard® Enterprise 5.50, Administrator help 24.4.1 Boot sector During the encryption process a volume's boot sector is swapped for the SafeGuard Enterprise boot sector. The SafeGuard Enterprise boot sector holds information about the location of the primary and backup KSA in clusters and sectors in relation to the start of the partition the size of the KSA Even if the SafeGuard Enterprise boot sector is damaged, encrypted volumes cannot be accessed. The tool BE_Restore can restore the damaged boot sector. For a detailed description of this utility refer to the SafeGuard Tools Guide. 24.4.2 Original boot sector The original boot sector is the one that is run after the DEK (Data Encryption Key) has been decrypted and the algorithm and the key have been loaded to the BE filter driver. If this boot sector is defective, Windows is unable to access the volume. Normally the common error message “Device is not formatted. Would you like to format it now? Yes/No” is displayed. Nonetheless, SafeGuard Enterprise will load the DEK for this volume. A tool that is used to repair the boot sector needs to be compatible with the SafeGuard Enterprise Upper Volume Filter. 24.5 Windows boot problems Its cryptographic design of the volume-specific key (boot sector, Key Storage Area KSA) makes SafeGuard Enterprise extremely flexible. You can save a damaged system by booting a restore medium from the SafeGuard Enterprise Power-on Authentication (Windows PE with the SafeGuard Enterprise encryption subsystem installed). These media have transparent en-/decryption access to volumes encrypted with SafeGuard Enterprise. The cause of the unbootable system can be remedied from there. 24.5.1 Encryption subsystem Encryption subsystems are for example BEFLT.sys. Carry out the procedure described under Windows boot problems and repair the system. 247 SafeGuard® Enterprise 5.50, Administrator help 24.5.2 GINA problems GINA problems such as circular loops may be resolved as follows: Carry out the procedure described under Windows boot problems and repair the system. 24.6 Setting up WinPE for SafeGuard Enterprise To get access to encrypted drives with a computer's BOOTKEY within a WinPE environment, SafeGuard Enterprise offers WinPE with the required SafeGuard Enterprise function modules and drivers. To start SetupWinPE enter the following command: SetupWinPE -pe2 <WinPE image file> WinPE image file being the full path name of a WinPE image file SetupWinPE makes all the changes needed. Note: Note that, with this type of WinPE environment, only encrypted drives that are encrypted with the BOOTKEY can be accessed. Drives that are encrypted with a user key cannot be accessed because the keys are not available in this environment. 24.7 “Slaving” a hard disk SafeGuard Enterprise allows encrypted volumes or hard disks to be enslaved. It permits the end user, the Windows administrator and the SafeGuard Enterprise Security Officer to connect or remove new volumes or hard disks in spite of sector-based encryption. A volume's Key Storage Area (KSA) holds all the information required, i.e.: The randomly generated DEK (Data Encryption Key). An ID for the encryption algorithm used to encrypt the volume. The list of GUIDs for the KEKs (Key Encryption Keys) that can encrypt and decrypt the DEK. The volume itself contains its size. A volume encrypted with SafeGuard Enterprise can be accessed from all SafeGuard Enterprise protected computers, provided that the user or computer possess a KEK for the KSA of the volume on their key ring. Users or computers must be able to decrypt the DEK encrypted by the KEK. Many users and computers can access a volume that has been encrypted with a distributable KEK such as an OU, group or domain key, because many users/computers of a domain have this key on their key ring. 248 SafeGuard® Enterprise 5.50, Administrator help However, a volume that is only encrypted with the individual boot key (“Boot_machinename”) of the SafeGuard Enterprise protected computer can only be accessed by that particular computer. If a volume does not boot on its original computer, it may be “enslaved” on another SafeGuard Enterprise protected computer. However, the correct book key cannot be accessed then. It has to be made accessible. Whenever the user attempts to access the volume from another computer, this can be done, because the KEKs in the KSA and the key rings of the other users or computers match again. 24.7.1 Example Alice has her own personal user key. Whenever she is logged on to her other computer (“Laptop_Alice”), she cannot access the volume that is encrypted with the boot key of the “SGNCLT” computer. The SafeGuard Enterprise protected computer “SGMCLT” only has its own boot key BOOT_SGMCLT. The Security Officer assigns the boot key “BOOT_SGNCLT” to Alice as follows: 1. Select user Alice 2. Click the “Binocular” icon in the SafeGuard Enterprise toolbar. This opens the search dialog which can also display boot keys. 3. Select the “BOOT_SGMCLT” key. Now Alice has two keys - “User_Alice” and “BOOT_SGMCLT”. This can be verified under Keys & Certificates. The “BOOT_SGMCLT” has been assigned twice - to the SGMCLT computer and to user Alice. Alice can now access the encrypted volume of any other SafeGuard Enterprise protected endpoint computer which she is able to log on to. She can then easily use tools such as Windows Explorer and regedit.exe to resolve the reason for the boot problem. If, in the worst case, the problem is not resolved, she can save data on another drive, reformat the volume or set it up as new again. 249 SafeGuard® Enterprise 5.50, Administrator help 25 Inventory and status data SafeGuard Enterprise reads a huge amount of inventory and status data from the endpoint computers. This data shows the current known global state of each computer. This data is clearly displayed in the SafeGuard Management Center in the Users & Computers area in the Inventory tab. As a Security Officer, you can view and print out the inventory and status data displayed in the SafeGuard Management Center. For example, you can print out reports as evidence that end devices have been encrypted. Wide-ranging sort and filter features provide support for you as you select the relevant data. The Inventory provides, e.g., the following data about each machine: Applied policy The encryption status of all media The POA status and the POA type Data on the installed SafeGuard Enterprise modules The WOL status User data 250 SafeGuard® Enterprise 5.50, Administrator help 25.1 Viewing inventory data Inventory data is accessed as follows: Open the SafeGuard Management Center. 1. In the navigation area of the SafeGuard Management Center, click the Users & Computers button. 2. In the navigation window, click the relevant container (domain, workgroup or computer) on the left-hand side. 3. In the action area, switch to the Inventory tab on the right-hand side. 4. In the Filter area, select the filter to be applied on the inventory display, see Filtering inventory data on page 252. Note: If you are selecting a particular computer, you receive the inventory data as soon as you switch to the Inventory tab. The Filter area is not available here. 5. In the Filter area, click the magnifier icon. The inventory and status data appears in a summarized table for all the machines in the container selected. The tabs Drives, Users and Features are also available for each machine. 251 SafeGuard® Enterprise 5.50, Administrator help By clicking a column header you can sort the inventory data based on the values of the selected column. The context menu for each column offers a number of features for sorting, grouping and adjusting the display. 25.1.1 Filtering inventory data When working from an OU, filters can be defined to limit the display based on particular criteria. The following fields are available for defining filters in the Filter area of the Inventory tab: Field Description Computer Name To display the inventory and status data for a particular computer, enter the computer's name in this field. Include sub-containers Activate this field, if you want to include sub-containers in the display. Show last modified Use this field to specify the number of last changes to be displayed. You can also use the Filter Editor to create user-defined filters. You can open the Filter Editor with the context menu for each column. In the Filter Builder window you can define your own filters and apply them to the column concerned. 25.1.2 Refreshing inventory data The user PCs usually send an update of the inventory data when the data have changed. The Request Inventory Refresh command can be used to manually request a refresh of the computer's current inventory data. This command is available for a particular computer or for all the computers in a node (optionally including sub-nodes) in the context menu and in the Actions menu in the SafeGuard Management Center menu bar. The command can also be selected using the context menu for the list entries. If you select this command or click the Request Inventory Refresh icon in the toolbar, the relevant computers send their current inventory data. 252 SafeGuard® Enterprise 5.50, Administrator help As is the case with other areas in the Management Center, to refresh the display in the SafeGuard Management Center, you can use the Refresh command, which you will find in the context menu for individual computers or all the computers in a node and in the View menu in the menu bar. You can also use the Refresh double-headed arrow icon in the toolbar to refresh the display. 25.1.3 Overview The individual columns in the overview show the following information: 253 Column Explanation Machine Name Shows the computer's name. Operating System Shows the computer's operating system. Last Policy Received Shows when (date and time) the computer received the last policy. Encrypted Drives Shows the computer's encrypted drives. Unencrypted Drives Shows the computer's unencrypted drives. POA Type Specifies whether the computer in question is a BitLocker client or a native SafeGuard Enterprise client. POA Specifies whether Power-on Authentication is activated for the computer. WOL Specifies whether Wake On LAN is activated for the computer. Modification Date Shows the date when the inventory data changed due to an inventory refresh request or the computer sending new inventory data. Refresh requested Shows the date of the last refresh request. The value displayed in this field will be deleted, when the request is processed by the computer. Parent DSN Shows the Distinguished Name of container object the computer is subordinated to. This column is only displayed, if the field Including subcontainers has been activated in the Filter area. SafeGuard® Enterprise 5.50, Administrator help 25.1.4 Drives tab The Drives tab shows the inventory and status data for the drives on the computer concerned. Column Explanation Drive Name Shows the name of the drive. Type Shows the drive type, e.g. Fixed, Removable Medium or CD-ROM/DVD. State Shows the drive's encryption status.

Column Explanation Module Name Shows the name of the installed SafeGuard Enterprise module. Version Shows the software version of the installed SafeGuard Enterprise module. 256 SafeGuard® Enterprise 5.50, Administrator help 25.2 Printing inventory reports The data shown in the Inventory tab can be printed out as inventory reports using the File menu in the SafeGuard Management Center menu bar. To get a print preview before printing, select File > Print Preview. The print preview provides various features, such as exporting the document in a range of output formats (for example, .PDF) or editing the page layout (for example, header and footer). To print the document immediately, select File > Print. 257 SafeGuard® Enterprise 5.50, Administrator help 26 Reports Recording security-related incidents is a prerequisite for detailed system analysis. The events logged facilitate the exact tracking of processes on a specific workstation or within a network. By logging events, you can for example verify security breaches committed by third parties. The logging functionality also supports the administrator or security officer in determining errors in granting user rights and correcting them. SafeGuard Enterprise logs all endpoint computer activities and status information as well as administrator actions and security-related events and saves them centrally. The logging functionality records events triggered by installed SafeGuard products. The type of logs is defined in logging policies. This is also where you specify the output and saving location for the logged events: the Windows Event Log of the respective endpoint computer or the SafeGuard Enterprise Database. Provided that you have the required rights as a security officer you can view, print and archive the status information and log reports displayed in the SafeGuard Management Center. The SafeGuard Management Center offers comprehensive sorting and filter functions which are very helpful when selecting relevant events from the information available. Automated analyses of the log database, e.g. via Crystal Reports or Microsoft System Center Operations Manager, are also possible. SafeGuard Enterprise protects the log entries against unauthorized manipulation using signatures on the client as well as on the server side. Depending on the logging policy defined and assigned, events of the following categories can be logged: Authentication Administration System Encryption Client Communication Access control 258 SafeGuard® Enterprise 5.50, Administrator help 26.1 Application scenarios The SafeGuard Enterprise logging functionality is a user-friendly and comprehensive solution for recording and analyzing events. The following examples show typical application scenarios for the SafeGuard Enterprise Reports functionality. Central monitoring of workstations within a network The responsible security officer wants to be informed about critical events (for example, unauthorized data access, a number of failed logon attempts within a specified time frame) on a regular basis. Using a logging policy, the security officer can configure logging processes to log all security-related events occurring on the endpoint computers concerned in a local log file. This log file is transferred to the SafeGuard Enterprise Database via the SafeGuard Enterprise Server after a number of events specified in another policy has been reached. The security officer can retrieve, view and analyze the events in the Event Viewer of the SafeGuard Management Center. Thus, the processes performed on different endpoint computers can be audited without staff being able to influence logging. Monitoring mobile users In general, mobile users are not constantly connected to the company network. Sales representatives in the field will for example disconnect their notebooks for a meeting. As soon as they log on to the network again, the SafeGuard Enterprise events logged during the offline period will be transferred. The logging functionality thus provides an exact overview on the user’s activities during the time that the relevant computer was not connected to the network. 26.2 Prerequisite A machine on which only the SafeGuard Enterprise Management Center is installed does not have a connection to the server after initial installation. To be able to use the logging functionality, the client package has to be executed on the machine. By doing so the machine is activated as a client at the server and the logging functionality can be used. For further information on client packages refer to the SafeGuard Enterprise Installation Manual. 259 SafeGuard® Enterprise 5.50, Administrator help 26.3 Destinations for logged events There are two possible destinations for logged events: the Windows Event Viewer or the SafeGuard Enterprise Database. Only events related to a SafeGuard product are written to the relevant destination. The output destinations for events to be logged are specified in the logging policy. 26.3.1 Windows Event Viewer Events for which you define the Windows Event Viewer as a destination in the logging policy will be logged in the Windows Event Viewer. The Windows Event Viewer can be used to display and manage logs for system, security and application events. You can also save these event logs. For these procedures an administrator account for the relevant endpoint computer is required. In the Windows Event Viewer an error code is displayed instead of a descriptive event text. Note: This chapter describes the processes of viewing, managing and analyzing event logs in the SafeGuard Management Center. For further information on viewing and managing event logs using the Windows Event Viewer, please refer to your Microsoft Documentation. 26.3.2 SafeGuard Enterprise Database Events for which you define the SafeGuard Enterprise Database as a destination in the logging policy are collected in a local log file in the local cache of the relevant endpoint computer in directory auditing\SGMTranslog. Log files are submitted to a transport mechanism which transfers them to the database via the SafeGuard Enterprise Server. By default, the file is submitted as soon as the transport mechanism has successfully established a connection to the server. To limit the size of a log file, you can define a maximum number of log entries in a policy of the type General Settings. The log file will be submitted to the transport queue of the SafeGuard Enterprise Server when the number of entries specified has been reached. The events logged in the central database can be displayed in the SafeGuard Enterprise Event Viewer. As a security officer you will need the relevant rights to view, analyze and manage the events logged in the database. 260 SafeGuard® Enterprise 5.50, Administrator help 26.4 Defining settings for logging Report settings are defined via two policies: General Settings policy In a General Settings policy, you can specify a maximum number of logged entries after which the log file containing the events destined for the central database is to be transferred to the SafeGuard Enterprise Database. This reduces the size of the individual log files to be transferred. This setting is optional. Logging policy The events to be logged are specified in a logging policy. In this policy, a security officer with the required policy rights defines which events will be logged to which output destination. The following two sections describe how to define these two policies for logging. 26.4.1 Defining the number of events for feedback To define the maximum number of logged entries for a log file, proceed as follows: You are in the Policies area of the Management Center. 1. Create a new General Settings policy or select an existing one. 2. In the Feedback after number of events field, specify the maximum number of events for a log file. 3. Save your settings. After assigning the policy the number of events specified applies to logging. 261 SafeGuard® Enterprise 5.50, Administrator help 26.4.2 Selecting events To select the events to be logged, proceed as follows: You are in the Policies area of the Management Center. 1. Create a new Logging policy or select an existing one. 2. In the action area on the right-hand side, all predefined events which can be logged are displayed under Logging. By clicking on the column headers you can sort the events by ID, Category etc. 3. To specify that an event is to be logged in the SafeGuard Enterprise Database, select the event by clicking in the column showing database icon Log events in database. For events to be logged in the Windows Event Viewer, click in the column showing event log icon Log in event log. By clicking repeatedly you can uncheck the event or set it to null. If you do not define a setting for an event, the relevant default value applies. To display the valid default values, click the default value magnifier icon Show default values for not configured settings in the SafeGuard Management Center toolbar. Note: You can also specify these settings via the context menu for the individual events. 4. For all events selected for logging a green tick symbol is displayed in the relevant column. Save your settings. After assigning the policy the selected events are logged in the relevant output destination. 262 SafeGuard® Enterprise 5.50, Administrator help Available events For a list of all events available for logging, see Events available for reports on page 280. 26.5 Viewing logged events If you have the required rights as a security officer, you can view the events logged in the central database in the SafeGuard Management Center Event Viewer. To retrieve the entries logged in the central database, proceed as follows: 1. In the navigation area of the SafeGuard Management Center, click Reports. 2. In the action area Event Viewer on the right-hand side, click the magnifier icon. All events logged in the central database are shown in the Event Viewer. 263 SafeGuard® Enterprise 5.50, Administrator help The individual columns show the following information concerning the events logged: Column Description Level (icon) Shows an icon indicating the event classification, e.g. warning, error. Event ID Shows a number identifying the event. Event Shows an event text, i.e. a description of the event. Category Classification of the event by the source, e.g. Encryption, Authentication, System. Application Shows the software area the event originated from, e.g. SGMAuth, SGBaseENc, SGMAS. Computer Shows the name of the computer on which the logged event occurred. Computer domain Shows the domain of the computer on which the logged event occurred. User Shows the user who was logged on at the time of the event. User domain Shows the domain of the user who was logged on at the time of the event. Log time Shows the system date and system time at which the event was logged on the endpoint computer. By clicking the relevant column headers you can sort the events by Level, Category etc. In addition, the context menu of the relevant columns offers a number of functions for sorting, grouping and customizing the Event Viewer. By double-clicking an entry in the Event Viewer you can display event details concerning the logged event. 264 SafeGuard® Enterprise 5.50, Administrator help 26.5.1 Applying filters to the SafeGuard Enterprise Event Viewer The SafeGuard Management Center offers comprehensive filter functions. Using these functions you can quickly retrieve the relevant events from the events displayed. The Filter area of the Event Viewer offers the following fields for defining filters: Field Description Categories Using this field you can filter the Event Viewer according to the source classification (e.g. Encryption, Authentication, System) shown in the Category column. Select the required categories from the drop-down list of the field. Error level Using this field you can filter the Event Viewer according to the Windows event classification (e.g. warning, error) shown in the Level column. Select the required levels from the drop-down list of the field. Show last In this field, you can define the number of events to be displayed. The events logged last will be displayed (by default the last 100 events). In addition, you can create user-defined filters using the Filter Editor. You can display the Filter Editor via the context menu of the individual report columns. In the Filter Builder window you can define filters and apply them to the relevant column. 265 SafeGuard® Enterprise 5.50, Administrator help 26.6 Printing reports You can print the event reports displayed in the SafeGuard Management Center Event Viewer via the File menu in the menu bar of the SafeGuard Management Center. To display a print preview prior to printing the report, select File > Print Preview. The print preview offers different functions, for example for exporting the relevant document into a number of output formats (e.g. .PDF) or editing the page layout (e.g. header and footer). To print the document without a print preview, select File > Print. 26.7 Concatenation of logged events The events destined for the central database are logged in the EVENT table of the SafeGuard Enterprise Database. For this table, special integrity protection can be applied, the events can be logged as a concatenated list in the EVENT table. Due to the concatenation, each entry in the list is dependent on the previous entry. If an entry is removed from the list, this is evident and can be verified via an integrity check. To enhance performance, the concatenation of events in the EVENT table is deactivated by default. However, you can also activate the concatenation of logged events for integrity checking purposes (see Checking the integrity of logged events on page 267). Note: When the concatenation of logged events is deactivated, special integrity protection does not apply to the EVENT table. 26.7.1 Activating the concatenation of logged events To activate event concatenation, proceed as follows: 1. Stop web service SGNSRV at the Web Server. 2. Delete all events from the database and create a backup during deletion (see Deleting selected or all events on page 267). Note: If you do not delete all old events from the database, the concatenation will not work correctly as the remaining old events did not have concatenation activated. 3. Set the following registry key to 0 or delete it: HKEY_LOCAL_MACHINE\SOFTWARE\Utimaco\SafeGuard Enterprise DWORD: DisableLogEventChaining = 0 4. Restart the web service. 266 SafeGuard® Enterprise 5.50, Administrator help The concatenation of logged events is activated. To deactivate the concatenation of events again, set the registry key to 1 . 26.8 Checking the integrity of logged events Prerequisite: For checking the integrity of logged events the concatenation of events in the EVENT table has to be activated. To check the integrity of the events shown in the SafeGuard Enterprise Event Viewer, proceed as follows: You are in the Reports area of the Management Center. In the SafeGuard Management Center menu bar, select Actions > Check integrity. You can also click the Check integrity of log events icon in the toolbar. A message is displayed informing you about the integrity of the events logged. Note: If event concatenation is deactivated, an error will be returned when checking the integrity of logged events in the SafeGuard Management Center. 26.9 Deleting selected or all events To delete selected events from the event log, proceed as follows: You are in the Reports area of the Management Center. 1. In the Event Viewer, select the events to be deleted. 2. To delete selected events, select Actions > Delete events or click the Delete events icon in the toolbar. To delete all events, select Actions > Delete all events or click the Delete all events icon in the toolbar. 3. Prior to deleting the selected events, the system displays the Back up events as window for creating a backup file (see Creating a backup file on page 268). The events selected are now deleted from the event log. 267 SafeGuard® Enterprise 5.50, Administrator help 26.10 Creating a backup file When you are deleting events, you can create a backup file of the report displayed in the SafeGuard Management Center Event Viewer. Upon selecting Actions > Delete events or Actions > Delete all events the Back up events as window for creating a backup file will be displayed prior to deleting the events. To create an .XML backup file of the event log, enter a file name and a file location and click OK. 26.11 Opening a backup file To open the .XML backup file created during a deletion process, proceed as follows: You are in the Reports area of the Management Center. 1. In the SafeGuard Management Center menu bar, select Actions > Open backup file. You can also click the Open backup file icon in the tool bar. 2. The Open Event Backup window is displayed. Select the backup file to be opened and click Open. The backup file has been opened and the events are shown in the SafeGuard Management Center Event Viewer. To return to the regular view of the Event Viewer, click the Open backup file icon in the toolbar again. 26.12 Scheduled event cleanup via script For automatic and efficient cleanup of the EVENT table four SQL scripts are available in the \tools directory on your SafeGuard Enterprise Product CD: spShrinkEventTable_install.sql ScheduledShrinkEventTable_install.sql spShrinkEventTable_uninstall.sql ScheduledShrinkEventTable_uninstall.sql The two scripts spShrinkEventTable_install.sql and ScheduledShrinkEventTable_install.sql install a stored procedure at the database server as well as a scheduled job which runs the stored procedure at defined regular intervals. The stored procedure moves events from the EVENT table to the backup log table EVENT_BACKUP leaving a defined number of latest events in the EVENT table. The two scripts spShrinkEventTable_uninstall.sql and ScheduledShrinkEventTable_uninstall.sql uninstall the stored procedure as well as the scheduled job and delete the EVENT_BACKUP table. 268 SafeGuard® Enterprise 5.50, Administrator help Note: If you use the stored procedure to move events from the EVENT table to the backup log table, event concatenation no longer applies. Therefore, to activate concatenation while also using the stored procedure for event cleanup does not make sense. For further details concerning concatenation, see Concatenation of logged events on page 266. 26.12.1 Creating the stored procedure The script spShrinkEventTable_install.sql creates a stored procedure which moves data from the EVENT table to a backup log table EVENT_BACKUP. If the EVENT_BACKUP table does not exist, it will be created automatically. The first line is “USE SafeGuard“. If you have selected a different name for your SafeGuard Enterprise database, modify the name accordingly. The stored procedure will leave the <n> latest events in the EVENT table und move the rest of the events to the EVENT_BACKUP table. The number of events to be left in the EVENT table is specified via a parameter. To execute the stored procedure, initiate the following command in SQL Server Management Studio (New Query): exec spShrinkEventTable 1000 The command example above moves all events except for the latest 1000 events. 269 SafeGuard® Enterprise 5.50, Administrator help 26.12.2 Creating a scheduled job for running the stored procedure To automatically clean up the EVENT table at regular intervals, you can create a job at the SQL server. The job can be created via the script ScheduledShrinkEventTable_install.sql or using the SQL Enterprise Manager. Note: The scheduled job does not work on SQL Express databases. For the job to be executed, the SQL Server Agent has to be running. As there is no SQL Server Agent on SQL Server Express installations jobs are in this case not supported. The script has to be executed in the msdb. If you have selected a different name for your SafeGuard Enterprise database than SafeGuard, modify the name accordingly. /* Default: Database name 'SafeGuard' change if required*/ SELECT @SafeGuardDataBase='SafeGuard' You can also specify the number of events to be left in the EVENT table. The default is 100.000. /* Default: keep the latest 100000 events, change if required*/ SELECT @ShrinkCommand='exec spShrinkEventTable 100000' You can specify whether a job run is to be logged in the NT Event Log. exec sp_add_job @job_name='AutoShrinkEventTable', @enabled=1, @notify_level_eventlog=3 The following values are available for parameter notify_level_eventlog : Value Result 3 Log every time the job runs. 2 Log, if the job fails. 1 Log, if the job was carried out successfully. 0 Do not log job run in NT Event Log. 270 SafeGuard® Enterprise 5.50, Administrator help You can specify how often the job run should be repeated in case it fails. exec sp_add_jobstep @retry_attempts=3 This example defines 3 job run attempts in case of failure. @retry_interval=60 This example defines a retry interval of 60 minutes. You can specify time schedule for running the job. exec sp_add_jobschedule @freq_type=4 This example defines that the job is run daily. @freq_interval=1 This example defines that the job is run once per day. @active_start_time=010000 This example defines that the job is run at 1 a.m. Note: The syntax for parameter @active_start_time stated above works with SQL Server 2005. The correct syntax for SQL Server 2000 is: @active_start_time='1:00:00' . Note: Besides the example values stated above, you can define a number of different schedule options with sp_add-jobschedule . For example, the job can be run every two minutes or only once per week. For detailed information refer to the Microsoft Transact SQL Documentation. 26.12.3 Cleaning up stored procedures, jobs and tables The script spShrinkEventTable_uninstall.sql deletes the stored procedure as well as the EVENT_BACKUP table. The script ScheduledShrinkEventTable_uninstall.sql deregisters the scheduled job. Note: When executing spShrinkEventTable_uninstall.sql , the EVENT_BACKUP table will be deleted with all data contained in it. 271 SafeGuard® Enterprise 5.50, Administrator help 26.13 Report Messages Templates Events are not logged with their complete event texts in the SafeGuard Enterprise Database. Only ID and the relevant parameter values are written to the database table. When retrieving the logged events in the SafeGuard Management Center Event Viewer, the parameter values and the text templates contained in the .dll are converted into the complete event text in the current SafeGuard Management Center system language. The templates used for event text can be edited and processed, for example using SQL queries. For this purpose, you can generate a table containing all text templates for event messages. Afterwards you can customize the templates according to your specific requirements. To create a table containing the text templates for the individual event IDs, proceed as follows: 1. In the menu bar of the SafeGuard Management Center, select Tools > Options. 2. In the Options window, go to tab Database. 3. In the Report Message Templates area click Create Table. The table containing the templates for the event IDs has been created in the current system language and can be customized. Note: Prior to generating the templates the table is cleared. If the templates have been generated for a language as described and a user generates the templates for a different language, the templates for the first language will be deleted. 272 SafeGuard® Enterprise 5.50, Administrator help 27 SafeGuard Enterprise and BitLocker Drive Encryption BitLocker Drive Encryption is a full disk encryption feature with pre-boot authentication included with Microsoft's Windows Vista and Windows 7 operating systems. It is designed to protect data by providing encryption for the boot volume. 27.1 How does SafeGuard Enterprise integrate BitLocker? SafeGuard Enterprise enables BitLocker Drive Encryption provided in a Windows Vista or Windows 7 Enterprise or Ultimate installation to be managed from the SafeGuard Management Center, like a native SafeGuard Enterprise Client. During installation of the SafeGuard Enterprise Client the feature BitLocker support needs to be explicitly selected to enable BitLocker integration. SafeGuard Enterprise’s central and fully transparent management of BitLocker thus allows for the use in heterogeneous IT environments. SafeGuard Enterprise not only integrates BitLocker Drive Encryption seamlessly, but even enhances it significantly. Security policies for BitLocker can be centrally rolled out thanks to SafeGuard Enterprise. Even critical processes such as key management and key recovery are available when BitLocker is managed with SafeGuard Enterprise. For SafeGuard Enterprise support of the BitLocker To Go enhancement in Windows 7 see SafeGuard Enterprise and BitLocker To Go on page 278. 27.2 Enhancement of BitLocker capabilities with SafeGuard Enterprise When BitLocker is managed with SafeGuard Enterprise, customers benefit in the following ways: 273 Besides the boot partition additional volumes of the local disk may be encrypted by BitLocker. SafeGuard Enterprise file-based encryption can be additionally applied to all volumes, including removable media. In the SafeGuard Management Center BitLocker computers can be easily managed: Security policies can be updated, distributed and automatically applied. The BitLocker encryption status is displayed. The BitLocker logon mode can be defined. BitLocker activation and key backup is simplified compared to native Vista environments. A BitLocker recovery mechanism for passwords and key files is enabled for boot as well as non-boot volumes. SafeGuard® Enterprise 5.50, Administrator help 27.3 When to use SafeGuard Enterprise without BitLocker Drive Encryption The SafeGuard Enterprise volume based encryption method offers some benefits over BitLocker Drive Encryption, such as: It additionally supports Windows XP and Vista Business (BitLocker only supports Vista Enterprise and Ultimate) It requires no special hard disk partition for installation (BitLocker requires its own partition) It supports different smartcards and tokens for pre-boot authentication (BitLocker supports no smartcards, only memory sticks that contain a copyable key file) It supports and differentiates between different users during pre-boot authentication (BitLocker does not differentiate between different users) It provides a way for forgotten passwords to be reset via the secure, dynamic challenge/ response mechanism (BitLocker uses a fixed 48-digit recovery key) It has a graphical user interface in pre-boot authentication (BitLocker has only text) It accepts complex passwords and password rules that are synchronized with Windows (BitLocker only permits a TPM PIN) It also allows sector-based encryption for removable media (Vista BitLocker encrypts no removable media. When a BitLocker client is used with SafeGuard Enterprise, file-based removable media encryption is possible.) 27.4 Managing BitLocker clients with SafeGuard Enterprise In the SafeGuard Enterprise Management Center BitLocker endpoint computers can be managed just like any native SafeGuard endpoint computers. As a security officer you can set encryption and authentication policies for the BitLocker endpoint computers and distribute them. Once a BitLocker endpoint computer is registered at SafeGuard Enterprise, information on user, computer, logon mode and encryption status is displayed. Events are logged for BitLocker clients as well. 274 SafeGuard® Enterprise 5.50, Administrator help Management of the BitLocker clients in SafeGuard Enterprise is transparent, which means that management functions work in general the same for BitLocker and native SafeGuard Enterprise clients. You can find out on the type of a computer in the Inventory of a container in Users & Computers. The column POA Type tells you, if the respective computer is a BitLocker client or a native SafeGuard Enterprise Client. 27.5 Encrypting with BitLocker via SafeGuard Enterprise With BitLocker Drive Encryption support in SafeGuard Enterprise you can encrypt the following: boot volume with BitLocker encryption and BitLocker keys other volumes with BitLocker encryption and BitLocker keys any data, for example of removable media with SafeGuard Enterprise file based encryption and SafeGuard Enterprise keys. Please note that with SafeGuard Enterprise BitLocker support external hard disks are handled as other volumes and not as removable media. Thus, they can be volume encrypted. 27.5.1 BitLocker encryption keys When encrypting the boot volume or other volumes with BitLocker via SafeGuard Enterprise the encryption keys are always generated by BitLocker. A key is generated by BitLocker for each volume and cannot be reused for any other purpose. It needs to be stored in a safe place. The advantage when using BitLocker with SafeGuard Enterprise is that for each BitLocker generated key a backup key is stored in the SafeGuard Enterprise database. This allows for setting up a help desk and recovery mechanism similar to the SafeGuard Enterprise Challenge/Response otherwise not available. However, it is not possible to select keys globally or reuse them as with SafeGuard Enterprise native clients. The keys are not displayed in the SafeGuard Management Center either. In case a volume is already encrypted with BitLocker before installing the BitLocker support of SafeGuard Enterprise, the administrator needs to backup the keys of the formerly encrypted volume by using the backup mechanisms offered by Microsoft. Note: In case a volume is encrypted when SafeGuard Enterprise BitLocker support is already installed, the administrator may save the backup keys (secured with a recovery password) in the Active Directory, in addition to the storage in the SafeGuard database. The administrator needs do so manually via the Windows Manage BDE tool and by saving them to a group policy. For Windows 2003 Server however, this requires to extend the Active Directory schema used, furthermore Domain Administrator rights are needed to recover the stored information. 275 SafeGuard® Enterprise 5.50, Administrator help 27.5.2 BitLocker algorithms in SafeGuard Enterprise BitLocker supports the following Advanced Encryption Standard (AES) algorithms: AES-128 AES-256 AES-128 with diffuser AES-256 with diffuser The diffuser is BitLocker specific and is not used for the SafeGuard Enterprise volume based encryption mode. If an algorithm with diffuser is selected for encryption, any non-BitLocker modules of SafeGuard Enterprise will automatically use the algorithm without diffuser. When a policy is assigned to both BitLocker enabled computers and native SafeGuard Enterprise computers, the SafeGuard Enterprise native computers will use the algorithm without diffuser and BitLocker computers will use the algorithm with diffuser. 27.5.3 Encryption policies for BitLocker Drive Encryption The security officer can create a policy for (initial) encryption in the SafeGuard Management Center and distribute it to the BitLocker endpoint computers where it is executed. As the BitLocker clients are managed transparently in the Management Center, the security officer does not have to make any special BitLocker settings for encryption. SafeGuard Enterprise knows of the status of the clients and selects the BitLocker encryption accordingly. When a BitLocker client is installed with SafeGuard Enterprise and volumes encryption is activated, the volumes are encrypted by BitLocker Drive Encryption. 276 SafeGuard® Enterprise 5.50, Administrator help 27.6 Authentication with BitLocker Drive Encryption BitLocker Drive Encryption offers a range of authentication options. BitLocker users can either authenticate via a Trusted Platform Module (TPM) or USB stick or a combination of both. The security officer can set the various logon modes in a policy in the SafeGuard Management Center and distribute it to the BitLocker user PCs. The following logon modes exist for SafeGuard Enterprise BitLocker users: TPM only TPM + PIN TPM + USB Stick USB Stick only (TPM-less) Trusted Platform module (TPM) TPM is a smartcard-like module on the motherboard performing cryptographic functions and digital signature operations. It can create, store and manage user keys. It is protected against attacks. USB-Stick The external keys can be stored on an unprotected USB-Stick. 27.7 Logging Events reported by the BitLocker Client are logged, just as for any other SafeGuard Enterprise client. It is not especially mentioned that the event refers to a BitLocker client. The events reported are the same as for any SafeGuard Enterprise client. 277 SafeGuard® Enterprise 5.50, Administrator help 28 SafeGuard Enterprise and BitLocker To Go With BitLocker To Go the BitLocker Drive Encryption functionality has been extended in Microsoft Windows 7 enabling users to encrypt internal volumes as well as volumes on removable media on endpoint computers. via the Windows Explorer context menu. When the SafeGuard Enterprise Device Encryption Client has been deployed with “BitLocker support” enabled, BitLocker To Go is supported. When the SafeGuard Enterprise Device Encryption Client has been deployed without activating “BitLocker support” or when the SafeGuard Data Exchange Client has been deployed, encryption via BitLocker To Go is not compatible and needs to be disabled in this case. However, encryption of internal volumes and removable media can be centrally and conveniently configured via SafeGuard Enterprise security policies. Volumes and removable media already encrypted via BitLocker To Go before SafeGuard Enterprise deployment will remain readable. To deactivate BitLocker To Go encryption, do the following: 1. In the Windows Group Policy Editor, select Default Domain Policy > Computer configuration > Policies > Administrative Templates (local computer)> Windows components > BitLocker drive encryption > Removable media. 2. Under Removable media, select the following policy: Manage the use of BitLocker on removable media. Set the options as follows: Select Enabled. Under Options, deselect: Users may apply BitLocker protection to removable media. Under Options, select: Users may stop and decrypt BitLocker protection on removable media. 3. Confirm with OK. BitLocker To Go encryption is deactivated on the endpoint computers. Users cannot encrypt new volumes via BitLocker To Go anymore. Volumes encrypted via BitLocker To Go before the deployment of the native SafeGuard Enterprise Device Encryption Client remain readable. The resulting Registry settings on the Client side are as follows: [HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\FVE] "RDVConfigureBDE"=dword:00000001 "RDVAllowBDE"=dword:00000000 278 SafeGuard® Enterprise 5.50, Administrator help "RDVDisableBDE"=dword:00000001 These Registry keys will also be set during the installation of the SafeGuard Enterprise Device Encryption Client so that Bitlocker To Go is also deactivated on computers without domain management like workgroup or standalone computers. 279 SafeGuard® Enterprise 5.50, Administrator help 29 Events available for reports The following table provides an overview on all events which can be selected for logging.
