2 About Sophos SafeGuard (SafeGuard
Easy)
Sophos SafeGuard (SafeGuard Easy) encrypts data transparently: users do not need to decide which data is to be encrypted. Encryption and decryption is performed in the background.
Encryption effectively prevents data from being read or changed by unauthorized persons. Sophos
SafeGuard encryption cannot be bypassed by connecting storage media to another system.
Sophos SafeGuard lets you:
■ Get set up quickly.
■ Protect the confidentiality of data.
■ Encrypt data using technology that is FIPS 140 compliant.
Endpoints protected by Sophos SafeGuard run the SafeGuard Power-on Authentication (POA) in the pre-boot phase of the endpoint, before the operating system starts. After the user has been properly authenticated at the SafeGuard POA, the operating system starts and the user is logged on to Windows.
4
The SafeGuard POA provides highly secure and user friendly features such as:
■ Tamper protection for Sophos SafeGuard full disk encryption.
■ Logon delays on false entries.
■ Customizable Windows-like graphical user interface.
■ Passthrough to Windows.
■ Multiple language and unicode support.
startup guide
Convenient administrative access
Sophos SafeGuard offers several features that aid IT operations on endpoints:
■ The SafeGuard Power-on Authentication can be configured for use with Wake on LAN, for example to facilitate patch management.
■ Service accounts enable members of the IT team to log on to endpoints for post-installation tasks without activating the SafeGuard Power-on Authentication.
■ POA user accounts are predefined local accounts that enable users (for example members of the IT team) to log on to encrypted endpoints for administrative tasks after the SafeGuard
Power-on Authentication has been activated.
Recovery options
For recovery, Sophos SafeGuard offers different options that are tailored to different recovery scenarios:
■ Logon recovery using Local Self Help
Local Self Help enables users who have forgotten their password to log on to their endpoints without the assistance of a helpdesk. Even in situations where neither telephone nor network connections are available (for example aboard an aircraft), users can regain access to their endpoints. To log on, they answer a predefined number of questions in the SafeGuard Power-on
Authentication.
Local Self Help reduces the number of calls concerning logon recovery, thus freeing the helpdesk staff from routine tasks and allowing them to concentrate on more complex support requests.
■ Recovery using Challenge/Response
The Challenge/Response recovery mechanism requires the assistance of the helpdesk. It helps users who cannot log on to their endpoints or access encrypted data. During the
Challenge/Response procedure, the user provides a challenge code generated on the endpoint to the helpdesk officer, who in turn generates a response code that authorizes the user to perform a specific action on the endpoint. With Challenge/Response, Sophos SafeGuard offers different workflows for typical recovery scenarios that require helpdesk assistance.
■ System recovery
Sophos SafeGuard offers various methods and tools for system recovery, such as a Sophos
SafeGuard customized Windows PE and Lenovo Rescue and Recovery. Problems with
Windows system and Sophos SafeGuard components can be addressed using these tools.
Recovery is based on a key recovery file created for each Sophos SafeGuard encrypted endpoint and typically stored on a network share. This recovery key ensures that the recovery process is not exploited to bypass data protection and is encrypted for additional security. The network share for storing these files as well as the required access rights to this share are automatically created during first-time configuration.

2.1 About Sophos SafeGuard (SafeGuard Easy) 7.0
Sophos SafeGuard provides powerful data protection through encryption and additional logon authentication.
This version of Sophos SafeGuard (SafeGuard Easy) supports Windows 7 and Windows 8 on endpoints with BIOS or UEFI.
■ For BIOS platforms you can choose between Sophos SafeGuard full disk encryption and
BitLocker encryption managed by Sophos SafeGuard. The BIOS version comes with the
BitLocker native recovery mechanism.
Note: If SafeGuard Power-on Authentication or SafeGuard full disk encryption is mentioned in this manual, it refers to Windows 7 BIOS endpoints only.
■ For UEFI platforms, use BitLocker managed by Sophos SafeGuard (SafeGuard Easy) for disk encryption. For these endpoints Sophos SafeGuard offers enhanced Challenge/Response capabilities. For details of the supported UEFI versions and restrictions to SafeGuard BitLocker
Challenge/Response support, please see the Release Notes at http://downloads.sophos.com/readmes/readsgeasy_7_eng.html
.

SafeGuard full disk encryption with SafeGuard Power-on Authentication (POA) is the Sophos module for encrypting volumes on endpoints. It comes with a Sophos implemented pre-boot authentication called SafeGuard Power-on Authentication (POA) which supports logon options like smartcard and fingerprint and a Challenge/Response mechanism for recovery.
startup guide
BitLocker with pre-boot authentication (PBA) managed by SafeGuard is the component that enables and manages the BitLocker encryption engine and the BitLocker pre-boot authentication.
It is available for BIOS and UEFI platforms:
■
■
The UEFI version additionally offers a SafeGuard Challenge/Response mechanism for BitLocker recovery in case users forget their PINs. For details of the required UEFI version, see the
Release Notes.
The BIOS version does not offer the recovery enhancements by the SafeGuard Challenge /
Response mechanism, but serves as a fallback option in case the requirements for the UEFI version are not met. The Sophos installer checks whether the requirements are met, and if not automatically installs the BitLocker version without Challenge/Response.
Sophos SafeGuard (SafeGuard Easy) uses a policy-based encryption strategy to protect information on endpoints.
Administration is carried out with the SafeGuard Policy Editor, which is used to create and manage security policies and to provide recovery functions. Policies are deployed to endpoints in configuration packages. On the user side, the main security functions are data encryption and protection against unauthorized access. Sophos SafeGuard can be seamlessly integrated into the user's normal environment and is easy and intuitive to use. The Sophos SafeGuard authentication system, SafeGuard Power-on Authentication (POA), provides powerful access protection and offers user-friendly support when recovering credentials.

15
SafeGuard Easy
9 Give administrators access to endpoints
Service staff might need to access and pre-configure endpoints once the encryption software is installed, for example with a central rollout. However, the first user who logs on after installation of the encryption software activates the SafeGuard POA and is added as a Sophos SafeGuard user to the endpoints. To avoid this, you can include them on a service account list. Service staff included on this list can then log on to the operating system of the endpoint after installation and carry out the necessary tasks without activating the SafeGuard POA and without being added as a Sophos SafeGuard user.
To configure a service account list:
1. In the SafeGuard Policy Editor navigation area, click Policies.
2. In the Policies navigation window, right-click Service Account Lists, select New and then
Service account list.
3. Enter a name for the list and click OK.
4. In the navigation window, under Service Account Lists, select the new list.
5. Right-click in the action area on the right-hand side and select Add from the context-menu. A new user line is added.
6. Enter the Windows User Name and the Domain Name in the respective columns and press
ENTER. To add further users, repeat this step. For further information, see the SafeGuard
Easy administrator help, chapter Additional information for entering user and domain names.
7. Click the Save icon in the toolbar to save your changes to the database.
The service account list is now registered. In the next steps you assign it to the policy.
8. In the navigation window, under Policy Items, select the Authentication policy item you have just copied.
9. Under Logon Options, select Service Account List and select the newly created list.
10. Click the Save icon in the toolbar to save your changes.
The service account list is configured. The Authentication policy item and the policy group it is part of are updated accordingly. Next publish the edited policy to a configuration package.
Note: You can edit further policy settings as required, for example to customize the SafeGuard
POA, to configure encryption or to enable Wake On LAN. For further information, see the
SafeGuard Easy administrator help, chapter Secure Wake On LAN.

11 Install encryption software and configuration package on endpoints
This chapter informs you how to prepare endpoint computers for encryption, install the software on a trial computer and use your own tools to distribute it on you other endpoints.
11.1 Prepare endpoints for encryption
■ Check if a user account is set up and active. The user needs to have a password.
■ Make sure that you have Windows administrator rights.
■ Create a full backup of the data.
■
■
Drives to be encrypted must be completely formatted and have a drive letter assigned to them.
Sophos provides a hardware configuration list to minimize the risk of conflicts between the
SafeGuard POA and your endpoint hardware. The list is contained within the encryption software installation package.
We recommend that you install an updated version of this configuration file before any significant deployment of Sophos SafeGuard. The file is updated on a monthly basis and made available to download from: http://www.sophos.com/en-us/support/knowledgebase/65700.aspx
.
■ Check the hard disk(s) for errors with this command: chkdsk %drive% /F /V /X
.
In some cases you might be prompted to restart the endpoint and run chkdsk again. For further information, see: http://www.sophos.com/en-us/support/knowledgebase/107081.aspx
You can check the results (log file) in the Windows Event Viewer:
Windows 7: Select Windows Logs, Application, Wininit.
■ Use the Windows built-in defrag tool to locate and consolidate fragmented boot files, data files, and folders on local volumes.
defrag %drive%
For further information, see: http://www.sophos.com/en-us/support/knowledgebase/109226.aspx
.
■ Uninstall third party boot managers, such as PROnetworks Boot Pro and Boot-US.
■ We recommend that you clean the master boot record (MBR). To install Sophos SafeGuard you need a clean, unique MBR. If you have used an imaging/cloning tool on the endpoint, it might no longer be clean.
18
startup guide
Start the endpoint from a Windows DVD and use the command FIXMBR within the Windows
Recovery Console. For further information, see: http://www.sophos.com/en-us/support/knowledgebase/108088.aspx
.
■ If the boot partition on the endpoint has been converted from FAT to NTFS and the endpoint has not been restarted since, restart the endpoint once. Otherwise the installation might not be completed successfully.
11.2 Carry out a trial installation
Carry out the trial installation of the encryption software on a different computer from the one
SafeGuard Policy Editor is installed on.
Prerequisites:
Endpoints must have been prepared for encryption, see Prepare endpoints for encryption (page

12 Recover a forgotten password
If the user has forgotten their password, there are two ways to recover it:
■ The user may recover it using Local Self Help. This is the recommended method.
■ The helpdesk may recover it using a Challenge/Response procedure.
12.1 Recover a forgotten password using Local Self Help
1. On the endpoint in the SafeGuard Power-on Authentication, the user enters their user name.
The Recovery button becomes active.
2. The user clicks Recovery.
■ If only Local Self Help is activated for logon recovery on the endpoint, it is then started automatically.
■ If both Local Self Help and Challenge/Response are displayed for logon recovery, the user clicks Local Self Help.
3. In the following five dialogs, the user answers a defined number of questions randomly selected from the questions stored on the endpoint. After answering the last one, the user confirms the answers with OK.
4. In the next dialog, the user can view the password by pressing ENTER or SPACEBAR, or by clicking the blue display box.
The password is displayed for 5 seconds at the maximum. Afterwards, the startup process continues automatically. The user can hide the password immediately by pressing ENTER, or SPACEBAR, or by clicking the blue display box again.
5. After reading the password, the user clicks OK.
The user is logged on at the SafeGuard Power-on Authentication and to Windows and can use the password for future logon.
12.2 Recover a forgotten password using
Challenge/Response
Prerequisites:
The key recovery file created for each endpoint during installation of the Sophos SafeGuard encryption software must be accessible to the helpdesk and the name of the file must be known.
Challenge/Response must be enabled using a policy for the endpoint.
Note:
startup guide
We recommend that you primarily use Local Self Help to recover a forgotten password. Local
Self Help allows the user to have the current password displayed and to continue using it. This avoids the need to reset the password or to involve the helpdesk.
1. On the endpoint in the SafeGuard Power-on Authentication, the user enters their user name.
The Recovery button becomes active.
2. The user clicks Recovery.
■ If only Challenge/Response is activated for logon recovery, it is then started automatically.
■ If both Challenge/Response and Local Self Help are displayed for logon recovery, the user clicks Challenge/Response.
A dialog is displayed indicating the name of the key recovery file required.
3. The user clicks Next. A random challenge code is displayed.
4. The user contacts the helpdesk and provides the name of the required key recovery file as well as the challenge code to the helpdesk.
5. In SafeGuard Policy Editor, the helpdesk launches the Recovery Wizard.
6. The helpdesk selects recovery of type Sophos SafeGuard Client, confirms the key and the challenge code and selects the required recovery action Boot SGN Client without user logon.
A response code in the form of an ASCII character string is generated and displayed.
7. The helpdesk provides the user with the response code, for example by phone or text message.
8. On the endpoint in the Challenge/Response Wizard, the user clicks Next to enter the response code provided. The endpoint is enabled to start through SafeGuard Power-on Authentication.
9. In the Windows logon dialog, the user does not know the correct password and needs to change the password at Windows level. This requires further recovery actions outside the scope of Sophos SafeGuard, using standard Windows means. We recommend that you use the following methods to reset the password at Windows level:
■ Using a service or administrator account available on the endpoint with the required Windows rights.
■ Using a Windows password reset disk on the endpoint.
10. The user enters the new Windows password that the helpdesk has provided. The user then changes this password immediately to a value only known to them.
A new user certificate for use in Sophos SafeGuard will be created automatically based on the newly chosen Windows password. This enables the user to log on to the computer again and to log on at the SafeGuard Power-on Authentication with the new password.
The user can log on to the endpoint and log on at the SafeGuard Power-on Authentication again with the new password and can use the password for future logon.
