Sophos Enterprise Console
3 Getting started with Sophos Enterprise
Console
This is an overview of the tasks you need to perform to protect your network after you have
installed Enterprise Console and completed the Download Security Software Wizard. For more
information about using Enterprise Console, refer to the other materials and sections mentioned.
We recommend that you refer to the Sophos Enterprise Console policy setup guide for advice on
best practices for using and managing Sophos security software. Sophos documentation is
published at http://www.sophos.com/en-us/support/documentation.
If you haven't completed the Download Security Software Wizard, see Run the Download
Security Software Wizard (page 76).
To protect your network, follow these steps:
1. Create groups.
You can create groups yourself, one by one, or you can import Active Directory containers,
with or without computers, and use them as Enterprise Console computer groups.
If you want to import Active Directory containers, see Import containers and computers from
Active Directory (page 40). We recommend that you first import containers from Active Directory
without computers, then assign group policies to the groups, and then add computers to the
groups, for example, by synchronizing the groups with Active Directory.
For information about creating groups manually, see What are groups for? (page 31) and other
topics in the subsection Creating and using groups under the Setting up Enterprise Console
section.
2. Set up policies.
Enterprise Console has a set of default policies that are essential to keep your network
protected. You can use default Updating and Anti-virus and HIPS policies out of the box.
To configure the firewall policy, run the Firewall policy wizard. See Set up a basic firewall
policy (page 115).
3. Discover computers on the network and add them to the console.
If you have imported containers and computers from Active Directory in step 1, you do not
need to do anything. Otherwise, see Choose how to discover computers (page 40) and other
topics in the subsection Discovering computers on the network under the Setting up Enterprise
Console section.
18
Help
4. Protect computers.
You can choose between two approaches to protecting your networked computers, depending
on which suits you best.
■
Using the Protect Computers Wizard
When you drag a computer from the Unassigned group and drop it onto another group, a
wizard is launched to help you protect the computers. See Protect computers automatically
(page 52) and other topics in the section Protecting computers.
■
Protecting computers automatically during synchronization with Active Directory
If you chose to synchronize with Active Directory, you can also choose to protect your
Windows computers automatically.You can do so in the Synchronize with Active Directory
Wizard or Synchronization properties dialog box. For instructions, see Use synchronization
to protect computers automatically (page 47).
5. Check that computers are protected.
When installation is complete, look at the list of computers in the new group again. In the
On-access column, you should see the word Active: this shows that the computer is protected
by on-access scanning, and that it is now managed by Enterprise Console. For more
information, see How do I check that my network is protected? (page 55)
6. Clean up computers.
If a virus, unwanted application, or other issue has been detected on your network, clean up
affected computers as described in Clean up computers now (page 62).
Additional protection options
By default, Sophos Endpoint Security and Control detects malware (viruses, Trojans, worms,
spyware), adware and other potentially unwanted applications, and suspicious behavior. It also
blocks access to websites that are known to host malware and scans content downloaded from
the internet.You can enable further security and productivity features, as described in the section
Configuring policies.
Encryption options
If your license includes encryption, you can protect your computers against unauthorized access.
Drives can be encrypted transparently and Power-on Authentication provides an additional
authentication mechanism before the operating system starts.
Administrative options
You can set up different roles in Enterprise Console, add rights to the roles, and then assign
Windows users and groups to the roles. The System Administrator role that includes the Sophos
Full Administrators Windows group has full rights and does not require setting up. For more
information, see About roles and sub-estates (page 20).
You can split your IT estate into sub-estates and assign Enterprise Console groups of computers
to the sub-estates. You can then control access to the sub-estates by assigning Windows users
and groups to them. The Default sub-estate contains all Enterprise Console groups, including
the Unassigned group. For more information about sub-estates, see About roles and sub-estates
(page 20).
19
Sophos Enterprise Console
4 Setting up Enterprise Console
4.1 Managing roles and sub-estates
4.1.1 About roles and sub-estates
Important: If you already use role-based administration, you must have the Role-based
administration right to set up roles and sub-estates. The System Administrator role that includes
the Sophos Full Administrators Windows group has full rights and does not require setting up.
For more information, see What are the preconfigured roles? (page 21) and What tasks do the
rights authorize? (page 24).
You can set up role-based access to the console by setting up roles, adding rights to the roles,
and then assigning Windows users and groups to the roles. For example, a Help Desk engineer
can update or clean up computers, but cannot configure policies, which is the responsibility of an
Administrator.
To open Enterprise Console, a user must be a member of the Sophos Console Administrators
group and be assigned to at least one Enterprise Console role and one sub-estate. Members of
the Sophos Full Administrators group have full access to Enterprise Console.
Note: If you want to allow a user to use a remote or additional Enterprise Console, see How can
another user use Enterprise Console? (page 30)
You can create your own roles or use preconfigured roles.
You can assign a user as many roles as you like, by adding to the roles either the individual user
or a Windows group the user belongs to.
If a user does not have rights to perform a certain task within the console, they can still view
configuration settings pertaining to that task. A user who is not assigned any role cannot open
Enterprise Console.
You can also restrict the computers and groups that users can perform operations on. You can
split your IT estate into sub-estates and assign Enterprise Console groups of computers to the
sub-estates. You can then control access to the sub-estates by assigning Windows users and
groups to them. The Default sub-estate contains all Enterprise Console groups, including the
Unassigned group.
A user can only see the sub-estate that they are assigned to. If a user has been assigned to more
than one sub-estate, they can choose which sub-estate to view, one sub-estate at a time. The
sub-estate that is open in Enterprise Console is the active sub-estate. A user cannot edit a policy
that is applied outside their active sub-estate.

4.1.14 How can another user use Enterprise Console?
Members of the Sophos Full Administrators group have full access to Enterprise Console.
You can allow other users to use Enterprise Console. To open Enterprise Console, a user must
be:
■
A member of the Sophos Console Administrators group.
■
Assigned to at least one Enterprise Console role.
■
Assigned to at least one Enterprise Console sub-estate.
If you want to assign a user to the Sophos Console Administrators group, use Windows tools to
add that user to the group.
To assign a user to an Enterprise Console role or sub-estate, on the Tools menu, click Manage
Roles and Sub-Estates. For more information about roles and sub-estates, see About roles and
sub-estates (page 20).
To use a remote or additional Enterprise Console, a user must be:
■
30
A member of the Sophos Console Administrators group on the server where the Enterprise
Console management server is installed.
Help
■
A member of the Distributed COM Users group on the server where the Enterprise Console
management server is installed. (The Distributed COM Users group is located in the Builtin
container of the Active Directory Users and Computers tool.)
■
Assigned to at least one Enterprise Console role.
■
Assigned to at least one Enterprise Console sub-estate.
4.2 Creating and using groups
4.2.1 What are groups for?
You must create groups and place computers in them before you can protect and manage those
computers.
Groups are useful because you can:
■
Have computers in different groups updated from different sources or on different schedules.
■
Use different anti-virus and HIPS, application control, firewall, and other policies for different
groups.
■
Manage computers more easily.
Tip: You can create groups within groups and apply a specific set of policies to each group and
subgroup.
4.2.2 What is a group?
A group
is a folder that holds a number of computers.
You can create groups yourself or you can import Active Directory containers, with or without
computers, and use them as computer groups in Enterprise Console. You can also set up
synchronization with Active Directory so that new computers and containers as well as other
changes in Active Directory are copied into Enterprise Console automatically.
Each group has settings for updating, anti-virus and HIPS protection, firewall protection, and so
on. All the computers in a group should usually use these settings, which are called a “policy.”
A group can contain subgroups.
4.2.3 What is the Unassigned group?
The Unassigned group is a group where Enterprise Console holds computers before you put
them into groups.
You cannot:
■
Apply policies to the Unassigned group.
■
Create subgroups in the Unassigned group.
■
Move or delete the Unassigned group.
31
Sophos Enterprise Console
4.2.4 Create a group
If you use role-based administration, you must have the Computer search, protection and
groups right to perform this task. For more information, see About roles and sub-estates (page
20).
To create a new group for computers:
1. In the Endpoints view, in the Groups pane (on the left-hand side of the console), select where
you want to create the group.
Click the computer name at the top if you want to create a new top-level group. Click an existing
group if you want to create a subgroup.
2. On the toolbar, click the Create group icon.
A “New Group” is added to the list, with its name highlighted.
3. Type a name for the group.
Updating, anti-virus and HIPS, application control, firewall, patch, data control, device control,
tamper protection, and web control policies are applied to the new group automatically. You can
edit these policies, or apply different policies. See Edit a policy (page 38) or Assign a policy to a
group (page 38).
Note: If the new group is a subgroup, it initially uses the same settings as the group it is within.
4.2.5 Add computers to a group
If you use role-based administration, you must have the Computer search, protection and
groups right to perform this task. For more information, see About roles and sub-estates (page
20).
1. Select the computers that you want to add to a group. For example, click the Unassigned
group and select computers there.
2. Drag and drop the computers onto the new group.
If you move unprotected computers from the Unassigned group to a group that has automatic
updating set up, a wizard is launched to help you protect them.
If you move computers from one group to another, they will use the same policies as the
computers already in the group they are moved to.
4.2.6 Delete computers from a group
If you use role-based administration, you must have the Computer search, protection and
groups right to perform this task. For more information, see About roles and sub-estates (page
20).
You can delete computers from a group, for example, if you want to remove entries for computers
that are no longer on the network.
Important: If you delete computers that are still on the network, they will no longer be listed or
managed by the console.
32

4.3 Creating and using policies
4.3.1 About policies
A policy is a collection of settings applied to all the computers in a group.
Note: Some features will be unavailable if your license does not include them.
■
The Updating policy specifies how computers are updated with new security software.
■
The Anti-virus and HIPS policy specifies how the security software scans computers for
viruses, Trojans, worms, spyware, adware, potentially unwanted applications, suspicious
behavior and suspicious files, and how it cleans them up.
■
The Application control policy specifies which applications are blocked and which are allowed
on your computers.
■
The Firewall policy specifies how the firewall protects computers.
■
The Data control policy specifies rules for monitoring or restricting the transfer of files, based
on file content, filename, or file type.
■
The Device control policy specifies which storage and networking devices are not authorized
for use on workstations.
■
The Patch policy specifies whether patch assessment is enabled and how often computers
are assessed for missing patches.
■
The Full disk encryption policy specifies how full disk encryption protects computers against
unauthorized access.
■
The Tamper protection policy specifies the password that allows authorized endpoint users
to re-configure, disable or uninstall Sophos security software.
■
The Web control policy specifies which websites can be browsed to by users. A notification
is displayed to users for sites that are configured as "block" or "warn."
You can create more than one policy of each type.
You can apply the same policy to more than one group.
4.3.2 What is a policy?
A policy is a collection of settings applied to all the computers in a group.
When you install Enterprise Console, default policies that offer a basic level of security are created
for you. These policies are applied to any groups you create. You can edit the default policies or
create new policies.
To learn more about different types of policy, see About policies (page 34)
4.3.3 What are the default policies?
When you install Enterprise Console, default policies are created for you.
34
Help
Note: Some features will be unavailable if your license does not include them.
Updating policy
The default updating policy in a fresh installation of Enterprise Console provides:
■
Automatic updating of computers every 10 minutes from the default location. The default
location is a UNC share \\<ComputerName>\SophosUpdate, where ComputerName is the
name of the computer where the update manager is installed.
Anti-virus and HIPS policy
The default anti-virus and HIPS policy in a fresh installation of Enterprise Console provides:
■
On-access scanning for viruses, Trojans, worms, spyware, and adware and other potentially
unwanted applications (but not suspicious files).
■
Detection of buffer overflows and malicious and suspicious behavior of programs running on
the system.
■
Blocking of access to websites that are known to host malware.
■
Scanning of content downloaded from the internet.
■
Security alerts displayed on the desktop of the affected computer and added to the event log.
For a full list of the default settings for the Anti-virus and HIPS policy in a fresh installation of
Enterprise Console, go to http://www.sophos.com/en-us/support/knowledgebase/27267.aspx.
Application control policy
By default, all applications and application types are allowed. On-access scanning for applications
you may want to control on your network is disabled.
Firewall policy
By default, the Sophos Client Firewall is enabled and blocks all non-essential traffic. Before you
use it throughout your network, you should configure it to allow the applications you want to use.
See Set up a basic firewall policy (page 115).
For a full list of the default firewall settings, see Sophos support knowledgebase article 57757
(http://www.sophos.com/en-us/support/knowledgebase/57757.aspx).
Data control policy
By default, data control is turned off and no rules are specified to monitor or restrict the transfer
of files to the internet or storage devices.
Device control policy
By default, device control is turned off and all devices are allowed.
35
Sophos Enterprise Console
Patch policy
By default, patch assessment is turned off. For new patch policies, assessment is turned on. Once
patch assessment is turned on, computers are assessed daily for missing patches (unless you
have changed the patch assessment interval).
Tamper protection policy
By default, tamper protection is turned off and no password is specified to allow authorized endpoint
users to re-configure, disable or uninstall Sophos security software.
Web control policy
By default, web control is turned off, and users can visit any site that is not restricted as part of
Enterprise Console's web protection. See About web protection (page 106).
Full disk encryption policy
By default, drives on computers are not encrypted. If you select volumes to encrypt in the default
policy, the selected volumes on computer drives are encrypted with fast initial encryption.
Note: The fast initial encryption mode may lead to a less secure state if a disk has been in use
before encryption is applied. Unused sectors may still contain data.
For logon, the Power-on Authentication is enabled. For recovery, the recovery method
Challenge/Response is enabled and configured.
4.3.4 Do I need to create my own policies?
When you install Enterprise Console,“default” policies are created for you. These policies are
applied to any groups you create.
The default policies offer a basic level of security, but to use features like network access control
or application control you need to create new policies or change the default policies.
Note: When you change the default policy, the change applies to all new policies you create.
Note: If you use role-based administration, you must have a respective Policy setting right to
create or edit a policy. For example, you must have the Policy setting - anti-virus and HIPS
right to create or edit an anti-virus and HIPS policy. For more information, see About roles and
sub-estates (page 20).
Updating policy
The default updating policy sets endpoints to check for updates to the recommended subscription
every 10 minutes from the default software distribution UNC share. To change subscriptions,
update locations and other settings, configure update policies as described in About updating
policy (page 76).
36
Help
Anti-virus and HIPS
The default anti-virus and HIPS policy protects computers against viruses and other malware.
However, to enable detection of other unwanted/suspicious applications or behavior, you may
want to create new policies, or change the default policy. See About the anti-virus and HIPS policy
(page 86).
Application control
To define and block unauthorized applications, configure application control policies as described
in About application control (page 142).
Firewall policy
To allow bona-fide applications access to a network, configure firewall policies as described in
Set up a basic firewall policy (page 115).
Data control
By default, data control is turned off. To restrict data leakage, configure data control policies as
described in About data control (page 144).
Device control
By default, device control is turned off. To restrict allowed hardware devices, configure device
control policies as described in About device control (page 159).
Patch
By default, patch assessment is turned off. For new patch policies, assessment is turned on. Once
patch assessment is turned on, computers are assessed daily for missing patches (unless you
have changed the patch assessment interval). To turn patch assessment on or off or to change
the assessment interval, configure patch policies as described in About patch assessment (page
175).
Tamper protection
By default, tamper protection is turned off. To enable tamper protection, configure tamper policies
as described in About tamper protection (page 173).
Web control
By default, web control is turned off. To turn on web control, and configure web control policies,
see About the web control policy (page 177).
37
Sophos Enterprise Console
Full disk encryption
By default, drives on computers are not encrypted. To protect data on computer drives against
unauthorized access by encrypting them and to specify further settings for logon and recovery,
configure full disk encryption policies as described in About full disk encryption (page 166).

4.5 Synchronizing with Active Directory
4.5.1 About synchronization with Active Directory
This section gives an overview of Active Directory synchronization.
What does Active Directory synchronization do for me?
With Active Directory synchronization, you can synchronize Enterprise Console groups with Active
Directory containers. New computers and containers discovered in Active Directory are copied
into Enterprise Console automatically. You can also choose to protect discovered Windows
workstations automatically. This allows you to minimize the time in which computers can become
infected and reduce the amount of work you need to do to organize and protect computers.
Note: Computers running Windows server operating systems, Mac OS, Linux, or UNIX are not
protected automatically. You must protect such computers manually.
After you have set up synchronization, you can set up email alerts to be sent to your chosen
recipients about new computers and containers discovered during future synchronizations. If you
choose to protect computers in synchronized Enterprise Console groups automatically, you can
also set up alerts about automatic protection failures.
43
Sophos Enterprise Console
How does Active Directory synchronization work?
In Enterprise Console, you can have both “normal,” unsynchronized groups that you manage
yourself and groups synchronized with Active Directory.
When setting up synchronization, you select or create a synchronization point: an Enterprise
Console group to be synchronized with an Active Directory container. All computers and subgroups
contained in the Active Directory are copied into Enterprise Console and kept synchronized with
Active Directory.
Note: To learn more about synchronization points, see What is a synchronization point? (page
45) To learn more about synchronized groups, see What is a synchronized group? (page 45)
After you set up synchronization with Active Directory, the synchronized part of Enterprise Console
group structure matches exactly the Active Directory container it is synchronized with. This means
the following:
■
If a new computer is added to the Active Directory container, then it also appears in Enterprise
Console.
■
If a computer is removed from Active Directory or is moved into an unsynchronized container,
then the computer is moved to the Unassigned group in Enterprise Console.
Note: When a computer is moved to the Unassigned group, it stops receiving new policies.
■
If a computer is moved from one synchronized container to another, then the computer is
moved from one Enterprise Console group to the other.
■
If a computer already exists in an Enterprise Console group when it is first synchronized, then
it is moved from that group to the synchronized group that matches its location in Active
Directory.
■
When a computer is moved into a new group with different policies, then new policies are sent
to the computer.
By default, synchronization occurs every 60 minutes.You may change the synchronization interval
if required.
How do I approach synchronization?
It is your decision what groups to synchronize with Active Directory and how many synchronization
points to set up. Consider whether the size of groups that will be created will be manageable.
You should be able to deploy software, scan and clean up computers easily. This is especially
important for the initial deployment.
The recommended approach is as follows:
1. Import the group structure (without computers), using the Import from Active Directory
function. For instructions, see Import containers and computers from Active Directory (page
40).
2. Review the imported group structure and choose your synchronization points.
3. Set up group policies and apply them to the groups and subgroups. For instructions, see Create
a policy (page 38) and Assign a policy to a group (page 38).
4. Synchronize your chosen synchronization points, one at a time, with Active Directory. For
instructions, see Synchronize with Active Directory (page 45).
44
Help
4.5.2 What is a synchronization point?
A synchronization point is an Enterprise Console group that points to a container (or subtree) in
Active Directory. A synchronization point can contain synchronized groups imported from Active
Directory.
In the Groups pane, a synchronization point appears as follows:
You can move, rename, or delete a synchronization point. You can also change policies and
synchronization settings, including automatic protection settings, for a synchronization point.
You cannot create or delete subgroups in a synchronization point, or move other groups into it.
You cannot move computers into or from the synchronization point.
4.5.3 What is a synchronized group?
A synchronized group is a subgroup of a synchronization point, imported from Active Directory.
In the Groups pane, a synchronized group appears as follows:
You can change policies assigned to a synchronized group.
You cannot change any synchronized group settings other than group policies.You cannot rename,
move, or delete a synchronized group. You cannot move computers or groups into or from the
group. You cannot create or delete subgroups in the group. You cannot change synchronization
settings for the group.

6.1.2 How does an update manager work?
Once you have configured an update manager, it:
■
Connects at a scheduled frequency to a data distribution warehouse at Sophos or on your
network.
■
Downloads updates to the threat detection data and updates for the security software to which
the administrator has subscribed.
■
Places the updated software in one or more network shares in a form suitable for installation
on endpoint computers.
The computers update automatically from the shares, provided the Sophos software installed on
them has been configured to do so, for example, by applying an updating policy.
6.1.3 View or edit update manager configuration

Sophos Enterprise Console
6.1.13 Add an additional update manager
Sophos Update Manager (SUM) is always installed on the computer where you install Enterprise
Console. If you selected Custom Setup during the installation, this is the computer where the
management server is installed.
You can add one or more additional update managers to your network. You may want to do this
to reduce the load on the update manager that is already installed and distribute updates more
efficiently. You can install an additional update manager on a computer that does not yet have
an update manager installed.
Important: Do not remove the update manager installed on the same computer as the Enterprise
Console management server. Enterprise Console cannot protect the network fully until this update
manager is configured with an update source. This will enable Enterprise Console to receive
necessary updates (for example, information about the versions of security software that endpoint
computers should be running, new and updated Content Control Lists for data control, or the list
of new controlled devices and applications).
To enable an additional update manager to download security software from Sophos or another
update manager via HTTP, open TCP port 80 (outbound) on the computer on which you want to
install the additional update manager.To enable the update manager to download security software
from another update manager via a UNC path, open the following outbound ports on the computer:
UDP port 137, UDP port 138, TCP port 139, and TCP port 445.
If the computer is running a version of Windows that includes the Network Discovery feature, and
the feature is turned off, turn it on and restart the computer.
If User Account Control (UAC) is enabled on the computer, turn off UAC and restart the computer.
You can turn UAC on again after you have installed the update manager and subscribed to Sophos
updates.
If the computer is in a domain, log on as a domain administrator.
If the computer is in a workgroup, log on as a local administrator.
The update manager installer is located on the computer where Enterprise Console management
server is installed, in the shared folder \\Servername\SUMInstallSet. To view the location
of the installer, go to the View menu and click Sophos Update Manager Installer Location.
You can install Sophos Update Manager using Windows Remote Desktop.
To install an additional update manager:
1. Run the Sophos Update Manager installer Setup.exe.
An installation wizard is launched.
2. On the Welcome page of the wizard, click Next.
3. On the License Agreement page, read the license agreement and click I accept the terms
in the license agreement if you agree to the terms. Click Next.
4. On the Destination folder page, accept the default or click Change and enter a new destination
folder. Click Next.
70
Help
5. On the Sophos Update Manager Account page, select an account that endpoint computers
will use to access the default update share created by the update manager. (The default update
share is \\<ComputerName>\SophosUpdate, where ComputerName is the name of the
computer where the update manager is installed.) This account must have read rights to the
share and does not need to have administrative rights.
You can select the default user, select an existing user, or create a new user.
By default, the installer will create the SophosUpdateMgr account with read rights to the
default update share and no interactive logon rights.
If you want to add more update shares later, select an existing account or create a new account
that has read rights to those shares. Otherwise, ensure that the SophosUpdateMgr account
has read rights to the shares.
6. On the Sophos Update Manager Account Details page, depending on the option you selected
on the previous page, enter a password for the default user, details for the new user, or select
an existing account.
The password for the account must comply with your password policy.
7. On the Ready to Install the Program page, click Install.
8. When installation is complete, click Finish.
The computer where you installed Sophos Update Manager should now appear in Enterprise
Console, Update managers view. (On the View menu, click Update Managers.)
To configure the update manager, select it, right-click, and then click View/Edit Configuration.
6.1.14 Publish security software on a web server
You might want to publish Sophos security software on a web server for computers to access via
HTTP. If you want to install Sophos Anti-Virus for UNIX, version 4, you must do this, although
you can leave this until you have downloaded Sophos Anti-Virus for UNIX, version 4 if you want
to.
To publish security software on a web server:
1. To find out the path of the shared folder to which the security software has been downloaded,
known as the bootstrap location:
a) In Enterprise Console, on the View menu, click Bootstrap Locations.
In the Bootstrap Locations dialog box, the Location column displays the bootstrap location
for each platform.
b) Make a note of the path up to but not including the CIDs folder. For example:
\\server name\SophosUpdate
2. Make the bootstrap location, including subfolders, available on the web server.
71
Sophos Enterprise Console
3. Specify usernames and passwords to prevent unauthorized access to this folder on the web
server.
The Sophos AutoUpdate component of Sophos Endpoint Security and Control supports the
following HTTP authentication types:
■
Basic
■
NTLM (v1 and v2)
■
Digest (AutoUpdate may fail to update with digest authentication on some web servers)
Sophos recommends that you use a secure option (i.e. NTLM v2) when configuring your
company's website for Sophos updating.
The documentation for your web server should describe how to share a folder over the web and
how to set up usernames and passwords for it. For more information about how to do this, contact
your web server vendor.
Using Internet Information Services (IIS) with Sophos software
If you use Internet Information Services (IIS) 6.0, which is supplied with Windows 2003 or later,
only files with extensions registered in the IIS MIME types list will be served. To ensure that IIS
serves Sophos files, add each extension used by those files to the list (alternatively use a wildcard
'.*'). To do this, find the top-level Sophos directory, right-click and then click Properties. In the
Web Site Properties dialog box, click the HTTP Headers tab. Then select MIME types and add
the extensions, mapping them to the MIME type "application/octet-stream".
If you use IIS with anonymous authentication and you want to use the web server as the primary
update server in your updating policy, you will still need to enter credentials for the primary server
in the updating policy. Otherwise, you will not be able to protect endpoint computers from the
console. See Change primary server credentials (page 79).
6.2 Configuring software subscriptions
6.2.1 About software subscriptions
A software subscription specifies which versions of endpoint software are downloaded from
Sophos for each platform.
The Download Security Software Wizard sets up a default subscription called “Recommended.”
This subscription includes the recommended versions of any selected software.
If you want to add software to your subscription or subscribe to a version other than the
recommended one, configure the subscription as described in Subscribe to security software
(page 74).
If you haven't completed the wizard after you installed Enterprise Console, see Run the Download
Security Software Wizard (page 76).
6.2.2 What types of updating are available?
For each platform (for example, Windows 2000 or later), there are several software packages
representing different types of updating and containing different versions of endpoint software.
72
Help
You can choose which software package to download from Sophos for further deployment to
endpoint computers by selecting one of the following updating types in the subscription.
Updating type
Description
Recommended
This is the default package. If you use this package, Sophos updates your software
regularly (usually every month) with:
Fixes for issues discovered by customers.
New features that are ready for general availability.
If you install Enterprise Console for the first time and accept the default settings,
this is the version that you will be on.
Preview
This package is aimed at IT and security administrators.
If you use this version, you receive new features before they are released in the
Recommended version. This means that you can test and evaluate them, perhaps
on a test network, before they become generally available.
Note: Sometimes the Preview package gives you the same software as
Recommended. This happens when no new features are ready to be tested in
customer environments.
Extended
The Extended version is aimed at customers who have a strict or conservative
process for installing updated software on their network.
If you use this version, you receive the same updates as the Recommended channel
but with a delay of several months. This means that any issues in the product have
been identified and fixed long before it is installed on your network.
Previous
Recommended
The previous version of the currently recommended package.
Previous Extended
The previous version of the current extended package.
This version can be useful for you if you want a little longer to test new software
before you roll it out to your network.
This version can be useful for you if you want a little longer to test new software
before you roll it out to your network.
Note: We may change the packages over time. For more information about currently available
software packages, see http://www.sophos.com/en-us/support/knowledgebase/119216.aspx.
The Download Security Software Wizard sets up a subscription that specifies the recommended
versions of any selected software.
The actual versions downloaded will usually change each month. To check what actual software
versions are downloaded, in the Software Subscription dialog box, select the package you want
to check and click Details.
73
Sophos Enterprise Console
6.2.3 Legacy updating types
Fixed versions
If in an earlier version of Enterprise Console you were subscribed to a fixed software version and
didn't change your software subscription before upgrading, you will still be subscribed to the fixed
version and it will continue to be downloaded.
A fixed version is a version that is updated with new threat detection data, but not with the latest
software version each month. An example of a fixed version of Sophos Endpoint Security and
Control for Windows is "10.2.3 VDL4.85G". It consists of a three-part version identifier—major
release identifier (10), minor release identifier (2), and maintenance release identifier (3)—and
threat detection engine and data version (VDL4.85G).
If you are subscribed to a fixed software version, we recommend that, to ensure best protection,
you change your subscription to a "recommended" package. For more information about software
packages, see What types of updating are available? (page 72).
Important: The option Automatically upgrade fixed version software when it is no longer
supported by Sophos is always enabled in Enterprise Console 5.2.1 and later and you cannot
disable it. If you didn't have this option enabled in your software subscription before the upgrade,
the option has been automatically enabled during the upgrade and the check box is no longer
displayed.
Fixed versions are downloaded for as long as they are available from Sophos. If a fixed version
is due to retire, you will see an alert in the Update managers view next to any update managers
that are subscribed to that version. If email alerting is active, the administrator will also receive
an email alert.
When a subscribed fixed version is retired, Enterprise Console will redefine the subscription to
use the oldest fixed version that is still available.
When you unsubscribe from a fixed software version, it will disappear from the list of available
packages in the Software Subscription dialog box.
For more information about legacy software packages, see
http://www.sophos.com/en-us/support/knowledgebase/112580.aspx.

6.3.3 Configuring update server locations
6.3.3.1 About update server locations
By default, computers update from a single primary source UNC share,
\\<ComputerName>\SophosUpdate, where <ComputerName> is the name of the Update
Manager's computer. You can also specify an alternative secondary source for updates and
enable location roaming. If endpoint computers cannot contact their primary source, they attempt
to update from their secondary source (if one has been specified). We recommend that you always
specify a secondary source.
Both primary and secondary update server locations may be either UNC shares or HTTP URLs
from any accessible Update Manager on your network. The secondary update server location
may alternatively be set to get updates directly from Sophos over the internet via HTTP.
Note: Update Managers may have multiple distribution shares available, depending on how you
have set them up.
6.3.3.2 Location roaming
6.3.3.2.1
About location roaming for laptops
Some laptop users may roam extensively or internationally within an organization. When location
roaming is enabled (on an updating policy for roaming laptops), roaming laptops attempt to locate
and update from the nearest update server location by querying other (fixed) endpoints on the
local network they are connected to, minimizing update delays and bandwidth costs.
77
Sophos Enterprise Console
A roaming laptop gets update server locations and credentials by querying fixed computers on
the same local network. If multiple locations are returned, the laptop determines which is nearest
and uses that. If none work, the laptop uses the primary (then secondary) location(s) defined in
its updating policy.
Note: When fixed computers send update locations and credentials to the laptop, passwords
are obscured both in transmission and storage. However, accounts set up for endpoints to read
update server locations should always be as restrictive as possible, allowing only read-only access.
See Specify where the software is placed (page 66).
If you want to know in more detail how location roaming works, see How does location roaming
work? (page 78)
Location roaming is only usable where:
■
There is a single common Enterprise Console for both roaming and fixed endpoints.
■
The fixed endpoints use the same software subscription as the roaming laptops.
■
There is a primary update location specified in the updating policy used by the roaming laptops.
■
Enterprise Console is version 4.7 or later and Endpoint Security and Control is version 9.7 or
later on both fixed and roaming endpoints.
■
Any third-party firewalls are configured to allow update location queries and responses. The
port used is normally UDP port 51235 but is configurable; for details see
http://www.sophos.com/en-us/support/knowledgebase/110371.aspx.
You enable location roaming as part of specifying sources for updates. Location roaming should
only be enabled on groups of machines that frequently move from office to office. For information
on how to enable location roaming, see Change primary server credentials (page 79).
For frequently asked questions about location roaming, see
http://www.sophos.com/en-us/support/knowledgebase/112830.aspx.
6.3.3.2.2
How does location roaming work?
Location roaming is a method of intelligent updating for roaming laptops where updates are
performed from a ''best'' update location and updating does not rely solely on the primary and
secondary update locations specified in the laptops' updating policy.
When location roaming is enabled, the following happens:
1. When a laptop changes its location, the Sophos AutoUpdate component of Endpoint Security
and Control installed on the laptop determines that the MAC address of the default gateway
on the connected network has changed since the last update. It then sends an ICMP broadcast
over the local subnet to neighboring AutoUpdate installations, using UDP port 51235 by default.
2. The neighboring AutoUpdate installations reply with their updating policy, using the same port.
Only the primary update location is sent in the response.
All Endpoint Security and Control 9.7 or later installations listen for broadcasts regardless of
whether location roaming is enabled or not.
Sensitive information in replies is obfuscated and fields are hashed for integrity.
Reply messages have a randomized reply time, to avoid message storms. The replies are
also ICMP broadcasts, so any other machine that would have replied with the same details
will also receive the broadcast and know not to respond.
78
Help
3. AutoUpdate chooses the "best" location from the locations received and checks whether the
sender is managed by the same Enterprise Console and the subscription ID matches the one
used by AutoUpdate on the laptop.
The "best" update location is determined based on the amount of hops required to access the
update location.
4. An update is then attempted and, if successful, the location is cached.
A maximum of four accessible update locations with the same subscription ID and the lowest
hop count are stored on the laptop (in the file iustatus.xml in the following location:
C:\Program Files\Sophos\AutoUpdate\data\status\iustatus.xml).
These update locations are checked every time AutoUpdate performs an update.
Note: If you need to revert back to using the primary and secondary update locations specified
in the updating policy (for example, if you wish to roll out customizations from the update
location specified in the policy), you will need to disable location roaming.
6.3.3.2.3

By default, security software is installed on computers and then kept updated from the source
specified on the Primary server tab. You can specify a different source for initial installation.
Note:
This setting applies only to Windows 2000 and later.
If your primary server is an HTTP (web) address, and you want to perform installation on the
computers from the console, you must specify a first-time install source.
To make the initial installation from a different source:
1. Check which updating policy is used by the group(s) of computers you want to configure.
See Check which policies a group uses (page 33).
2. In the Policies pane, double-click Updating. Then double-click the policy you want to change.
3. In the Updating policy dialog box, on the Initial install source tab, clear the Use primary
server address check box. Then enter the address of the source you want to use.

6.4 Monitoring the update manager
6.4.1 Monitor update managers
Check the update manager status on the Dashboard
The status of the update managers is displayed in the Updates panel on the Dashboard. This
will tell you when the last update was downloaded from Sophos and display a warning if the time
since the last update exceeds the warning or critical threshold.
Note: The Updates section of the dashboard does not report an alert or error if an update manager
is temporarily unable to update. Alerts and errors are only generated if the time since the last
update of the update manager exceeds the warning or critical threshold set in Configure the
Dashboard (page 56).
Check the update manager alerts and errors
Update manager alerts and errors are displayed in the Update managers view, Alerts and Errors
columns, respectively.
If you subscribed to a fixed version of software, an alert will be displayed when that version is
nearing retirement or is retired. An alert will also be displayed if your product license has changed.
To view update manager alerts and errors:
1. If you are in the Endpoints view, click the Update managers button on the toolbar to display
the Update managers view.
2. In the list of update managers, look in the Alerts and Errors columns for any possible problems.
3. If there is an alert or error displayed next to an update manager, right-click that update manager
and click View Update Manager Details.
In the Update manager details dialog box, you can see the time of the last threat detection
data and software updates, status of the subscription or subscriptions that the update manager
keeps up to date, and update manager status.
4. To learn more about a particular update manager status and for information on how to resolve
it, follow the link in the Description column.
If you need to check or change your subscription, for example, if the product you are subscribed
to is nearing retirement, or your product license has changed and the new license does not include
that product, see Subscribe to security software (page 74).
If new features become available as a result of a license change, you may need to configure new
policies before you can use the features. You can find help with configuring the new policies in
the Configuring policies section.
Subscribe to email alerts
You can set up email alerts to be sent to your chosen recipients when the product version you
are subscribed to is nearing retirement or is retired, or when your Sophos product features change
83
Sophos Enterprise Console
as a result of a license change. For more information, see Set up software subscription alerts
(page 186).
6.4.2 Clear update manager alerts from the console
If you use role-based administration, you must have the Remediation - cleanup right to clear
alerts from the console. For more information, see About roles and sub-estates (page 20).
To clear update manager alerts from the console:
1. In the Update managers view, select the update manager(s) for which you want to clear alerts.
Right-click and select Acknowledge Alerts.
The Update manager alerts dialog box is displayed.
2. To clear alerts from the console, select the alerts you want to clear and click Acknowledge.
Acknowledged (cleared) alerts are no longer displayed in the console.
6.5 Update out-of-date computers
If you use role-based administration, you must have the Remediation - updating and scanning
right to update computers. For more information, see About roles and sub-estates (page 20).
After you have set up the updating policies and applied them to your networked computers, the
computers are kept up to date automatically. You do not need to update computers manually
unless there is a problem with updating.
If in the Endpoints view, in the computer list, you see a clock icon next to a computer in the Up
to date column on the Status tab, the computer has out-of-date security software. The text
indicates how long the computer has been out of date.
A computer can be out of date for one of two reasons:
■
That computer has failed to fetch an update from the server.
■
The server itself does not have the latest Sophos software.
To diagnose the problem and update the computers:
1. In the Endpoints view, select the group that contains out-of-date computers.
2. On the Status tab, click the Up to date column heading to sort computers by up-to-dateness.
3. Click the Update details tab and look in the Primary server column.
This shows you the directory that each computer updates from.
4. Now look at the computers that update from one particular directory.
■
■
84
If some are out of date, but others are not, the problem is with individual computers. Select
them, right-click and click Update Computers Now.
If all are out of date, the problem could be with the directory. On the View menu, click
Update Managers. Select the update manager that maintains the directory that you suspect
to be out of date, right-click and click Update Now. Then on the View menu, click
Endpoints. Select the out-of-date computers, right-click and click Update Computers
Now.
Help
If you have several update managers and are not sure which one maintains the out-of-date
directory, use the Updating Hierarchy report to see which shares are maintained by each
update manager. To view the Updating Hierarchy report, on the Tools menu, click Manage
Reports. In the Report Manager dialog box, select Updating hierarchy and click Run. Look
in the “Shares managed by update managers” section of the report.

7.1.3 On-access scanning
7.1.3.1 About on-access scanning best protection
This section contains recommendations to help you get the best from on-access scanning.
We recommend that you use the default on-access scan settings, as they represent the best
balance between protecting your computer against threats and overall system performance. For
information about the recommended on-access scan settings, see Sophos support knowledgebase
article 114345 (http://www.sophos.com/en-us/support/knowledgebase/114345.aspx).
We recommend that you refer to the Sophos Enterprise Console policy setup guide for advice on
best practices for using and managing Sophos security software. Sophos documentation is
published at http://www.sophos.com/en-us/support/documentation.
7.1.3.2 Configure on-access scanning
If you use role-based administration:
■
You must have the Policy setting - anti-virus and HIPS right to perform this task.
■
You cannot edit a policy if it is applied outside your active sub-estate.
For more information, see About roles and sub-estates (page 20).
Caution: On-access scanning may not detect viruses if certain encryption software is installed.
Change the startup processes to ensure that files are decrypted when on-access scanning begins.
For more information on how to use anti-virus and HIPS policy with encryption software, see
Sophos support knowledgebase article 12790
(http://www.sophos.com/en-us/support/knowledgebase/12790.aspx).

productivity and system efficiency.
PUAs (Potentially Unwanted Applications) are
not malicious, but are generally considered
unsuitable for business networks.
Suspicious files
Suspicious files display certain characteristics (for
example, dynamic decompression code) that are
commonly, but not exclusively, found in malware.
However, these characteristics are not sufficiently
strong for the file to be identified as a new piece of
malware.
Note: This option applies only to Sophos Endpoint
Security and Control for Windows 2000 and later.
89

Description
Allow access to drives with infected boot
sectors
Allow access to an infected bootable removable
medium or device such as a bootable CD, floppy
disk, or USB flash drive.
Use this option only if advised to by Sophos
technical support.
Scan inside archive files
Scan the contents of archives or compressed files
before they are downloaded or emailed from
managed computers.
We recommend that you leave this option turned
off, as it makes scanning significantly slower.
Users will still be protected against any threats in
archives or compressed files, as any components
of an archive or compressed file that may be
malware will be blocked by on-access scanning:
When users open a file extracted from the
archive file, the extracted file is scanned.
Files compressed with dynamic compression
utilities such as PKLite, LZEXE, and Diet are
scanned.
Scan system memory
Run an hourly background scan that detects
malware hiding in the computer's system memory
(the memory that is used by the operating system).
7.1.3.3 Turn on-access scanning on or off
If you use role-based administration:
■
You must have the Policy setting - anti-virus and HIPS right to perform this task.
■
You cannot edit a policy if it is applied outside your active sub-estate.
For more information, see About roles and sub-estates (page 20).
By default, Sophos Sophos Endpoint Security and Control scans files as the user attempts to
access them, and denies access unless the file is clean.
You may decide to turn off on-access scanning on Exchange servers or other servers where
performance might be affected. In this case, put the servers in a special group and change the
anti-virus and HIPS policy used for that group as shown below.

To exclude files that are not stored on local drives, select the Exclude remote files check
box. You might select this if you want to increase speed of access to such files and you trust
the available remote file locations.
Important: If you select Exclude remote files on the Windows Exclusions tab, data control
will not scan files uploaded or attached from a network location using a monitored application, for
example, an email client, a web browser, or an instant messaging (IM) client. This is because
data control uses the same set of exclusions as the Sophos Anti-Virus on-access scanner, so if
remote file scanning is disabled, it will not send any remote files for a data control check. This
restriction does not apply to storage device monitoring.
You can export the list of Windows exclusions to a file and then import it into another policy. For

Option
Description
Scan inside archive files
Scan the contents of archives and other
compressed files.
We don't recommend that you scan inside archive
files during a scheduled scan, as it will add a
significant amount of time to the scan. We
recommend instead that you use on-access
scanning (on-read and on-write) to protect your
network. Any malware components of an unpacked
archive will be blocked by the on-read and on-write
scanners when they are accessed.
If you would like to scan all archives on a few
computers using a scheduled scan, we recommend
that you do the following:
Create an extra scheduled scan.
On the Scheduled scan extensions and
exclusions dialog box, add only the archive
extensions to the list of extensions to be
scanned.
Make sure that Scan all files is disabled.
This will allow you to scan the archive files whilst
making the scan as short as possible.
Scan system memory
Detect malware hiding in the computer's system
memory (the memory that is used by the operating
system).
Run scan at lower priority
On Windows Vista and above, run the scheduled
scan with lower priority so that it has minimal impact
on user applications.

7.1.5 Behavior monitoring
7.1.5.1 About behavior monitoring
As part of on-access scanning, Sophos Behavior Monitoring protects Windows computers from
unidentified or "zero-day" threats and suspicious behavior.
Runtime detection can intercept threats that cannot be detected before execution. Behavior
monitoring uses the following runtime detection methods to intercept threats:
■
Malicious and suspicious behavior detection
■
Buffer overflow detection
Malicious and suspicious behavior detection
Suspicious behavior detection uses Sophos’s Host Intrusion Prevention System (HIPS) to
dynamically analyze the behavior of all programs running on the computer to detect and block
activity that appears to be malicious. Suspicious behavior may include changes to the registry
that could allow a virus to run automatically when the computer is restarted.
Suspicious behavior detection watches all system processes for signs of active malware, such
as suspicious writes to the registry or file copy actions. It can be set to warn the administrator
and/or block the process.
Malicious behavior detection dynamically analyses all programs running on the computer to detect
and block activity that is known to be malicious.
Buffer overflow detection
Buffer overflow detection is important for dealing with zero-day exploits.
It dynamically analyzes the behavior of programs running on the system in order to detect when
an attempt is made to exploit a running process using buffer overflow techniques. It will catch
attacks targeting security vulnerabilities in both operating system software and applications.
7.1.5.2 Enable behavior monitoring
If you use role-based administration:

7.1.6 Sophos Live Protection
7.1.6.1 About Sophos Live Protection
Sophos Live Protection uses in-the-cloud technology to instantly decide whether a suspicious file
is a threat and take action specified in the anti-virus and HIPS policy.
Live Protection improves detection of new malware without the risk of unwanted detections. This
is achieved by doing an instant lookup against the very latest known malicious files. When new
malware is identified, Sophos can send out updates within seconds.
104
Help
To take full advantage of Live Protection, you must ensure that the following options are enabled.
■
Enable Live Protection
If the anti-virus scan on an endpoint computer has identified a file as suspicious, but cannot
further identify it as either clean or malicious based on the threat identity (IDE) files stored on
the computer, certain file characteristics such as checksum are sent to Sophos to assist with
further analysis. The in-the-cloud checking performs an instant lookup of a suspicious file in
the SophosLabs database. If the file is identified as clean or malicious, the decision is sent
back to the computer and the status of the file is automatically updated.
■
Automatically send file samples to Sophos
If a file is deemed potentially malicious but cannot be positively identified as malicious based
on its characteristics alone, Live Protection allows Sophos to request a sample of the file. If
this option is enabled and Sophos does not already hold a sample of the file, the file is submitted
automatically.
Submission of such sample files helps Sophos to continuously enhance detection of malware
without the risk of false positives.
Note: The maximum sample size is 10 MB. The timeout for sample upload is 30 seconds. It
is not recommended to automatically send samples over a slow connection (less than 56
Kbps).
Important: You must ensure that Sophos domain to which the file data is sent is trusted in your
web filtering solution. For details, see support knowledgebase article 62637
(http://www.sophos.com/en-us/support/knowledgebase/62637.aspx).
If you use a Sophos web filtering solution, for example the WS1000 Web Appliance, you do not
need to do anything - Sophos domains are already trusted.
7.1.6.2 Turn Sophos Live Protection on or off
If you use role-based administration:
■
You must have the Policy setting - anti-virus and HIPS right to perform this task.
■
You cannot edit a policy if it is applied outside your active sub-estate.
For more information, see About roles and sub-estates (page 20).
By default, Endpoint Security and Control sends file data such as checksums to Sophos, but does
not send sample files. To take full advantage of Sophos Live Protection, you must enable both
Sophos Live Protection options.

7.1.7 Web protection
7.1.7.1 About web protection
Web protection provides enhanced protection against web threats. It includes the following features:
■
Live URL filtering, which blocks access to websites that are known to host malware. This
feature works by performing a real-time lookup against Sophos’s online database of infected
websites.
■
Content scanning, which scans data and files downloaded from the internet (or intranet) and
proactively detects malicious content. This feature scans content hosted at any locations,
including those not listed in the database of infected websites.
Web protection is supported on the following web browsers: Internet Explorer, Firefox, Google
Chrome, Safari and Opera. Web content accessed via an unsupported browser is not filtered and
will not be blocked.
When access to a malicious website is blocked, an event is logged that can be viewed in the Web
Event Viewer and in the Computer details of the endpoint computer where the event occurred.
If you use the Web Control feature, both web protection and web control events are displayed in
the Web Event Viewer and Computer details. See View web events (page 202) and View latest
web events on a computer (page 203).
By default, web protection is enabled. For information on how to turn web protection on or off,
see Turn web protection on or off (page 106).
Note: If you want to have more control over which websites users are allowed to access, for
example, if you wish to protect users from visiting websites for which your organization could be
legally liable, use the Web Control feature. For more information, see About the web control policy
(page 177).
7.1.7.2 Turn web protection on or off
If you use role-based administration:
■
You must have the Policy setting - anti-virus and HIPS right to perform this task.

7.1.8 Scanned file types and exclusions
7.1.8.1 About changing which file types are scanned
By default, Sophos Endpoint Security and Control scans file types that are vulnerable to viruses.
The file types that are scanned by default not only differ between operating systems, but also
change as the product is updated.
To see a list of the file types that are scanned by default, go to a computer with the relevant
operating system, open Sophos Endpoint Security and Control or Sophos Anti-Virus, and then
look for the extensions configuration page.
You can also choose to scan additional file types or exempt some file types from scanning.
Windows
To see a list of the file types scanned by default on a Windows computer:
1. Open Sophos Endpoint Security and Control.
2. Under Anti-virus and HIPS, click Configure anti-virus and HIPS, and then click On-demand
extensions and exclusions.
For information about scanning additional file types or exempting some file types from scanning
on a Windows computer, see the following topics:
■
Specify on-access scanning file extensions (page 92)
■
Specify scheduled scanning file extensions (page 99)
Mac OS X
Sophos Anti-Virus for Mac OS X scans all file extensions during on-access scanning. To change
the settings for scheduled scanning, see Specify scheduled scanning file extensions (page 99).

To make changes on a UNIX computer, use the savscan command as described in the Sophos
Anti-Virus for UNIX configuration guide.
7.1.8.2 Items that can be excluded from scanning
On each type of computer, there are different limitations on the items that you can exclude from
scanning.
Windows
On Windows, you can exclude drives, folders and files.
You can use the wildcards * and ?
The wildcard ? can be used only in a filename or extension. It generally matches any single
character. However, when used at the end of a filename or extension, it matches any single
character or no characters. For example file??.txt matches file.txt, file1.txt and file12.txt but not
file123.txt.
The wildcard * can be used only in a filename or extension, in the form [filename].* or *.[extension].
For example, file*.txt, file.txt* and file.*txt are invalid.
For more information and examples, see Specifying scanning exclusions for Windows (page 109).
Mac OS X
On Mac OS X, you can exclude files, folders, and volumes.
You can specify which items are excluded by prefixing or suffixing the exclusion with a slash or
suffixing the exclusion with a double slash.
For more information, see the Sophos Anti-Virus for Mac OS X Help.
Linux or UNIX
On Linux and UNIX, you can exclude directories and files.
You can specify any POSIX path, whether it is a file or a directory, for example, /folder/file. You
may use the wildcards ? and *.
Note: Enterprise Console only supports path-based Linux and UNIX exclusions. You can also
set up other types of exclusion directly on the managed computers. Then you can use regular
expressions, exclude file types and filesystems. For information on how to do this, see the Sophos
Anti-Virus for Linux configuration guide or the Sophos Anti-Virus for UNIX configuration guide.
If you set up another path-based exclusion on a managed Linux or UNIX computer, this computer
will be reported to the console as differing from the group policy.

Exclude items from scheduled scanning (page 100)
7.1.8.3 Specifying scanning exclusions for Windows
Standard naming conventions
Sophos Anti-Virus validates the paths and file names of scanning exclusion items against standard
Windows naming conventions. For example, a folder name may contain spaces but may not
contain only spaces.
Exclude a specific file
Specify both the path and file name to exclude a specific file. The path can include a drive letter
or network share name:
C:\Documents\CV.doc
\\Server\Users\Documents\CV.doc
Note: To make sure that exclusions are always applied correctly, add both the long and
8.3-compliant file and folder names:
C:\Program Files\Sophos\Sophos Anti-Virus
C:\Progra~1\Sophos\Sophos~1
For more information, see http://www.sophos.com/en-us/support/knowledgebase/13045.aspx.
Exclude all files with the same name
Specify a file name without a path to exclude all files with that name wherever they are located
in the file system:
spacer.gif
Exclude everything on a drive or network share
Specify a drive letter or network share name to exclude everything on that drive or network share:
C:
\\Server\<sharename>\
Note: When you specify a network share, remember to include the trailing slash.
Exclude a specific folder
Specify a folder path including a drive letter or network share name to exclude everything in that
folder and below:
D:\Tools\logs
109
Sophos Enterprise Console
Exclude all folders with the same name
Specify a folder path without a drive letter or network share name to exclude everything from that
folder and below on any drive or network share. For example, \Tools\logs excludes the
following folders:
C:\Tools\logs
\\Server\Tools\logs
Note: You must specify the entire path up to the drive letter or network share name. In the
example above, specifying \logs would not exclude any files.
The ? and * wildcards
Use the ? wildcard in a file name or extension to match any single character.
At the end of a file name or extension, the ? wildcard matches any single character or no
characters: For example, file??.txt matches file.txt, file1.txt, and file12.txt, but
not file123.txt.
Use the * wildcard in a file name or extension, in the form [file name].* or *.[extension]:
Correct
file.*
*.txt
Incorrect
file*.txt
file.txt*
file.*txt
Multiple file extensions
File names with multiple extensions are treated as if the last extension is the extension and the
rest are part of the file name:
MySample.txt.doc = file name MySample.txt + extension .doc.

If you want to authorize a website that Sophos has classified as malicious, you can add it to the
list of authorized sites. Authorizing a website will prevent URLs from that website being verified
with Sophos's online web filtering service.
Caution: Authorizing a website that Sophos has classified as malicious could expose your users
to threats. Make sure that it is safe to visit the website before you authorize it.
To authorize a website:
1. Check which anti-virus and HIPS policy is used by the group(s) of computers you want to
configure.
See Check which policies a group uses (page 33).
2. In the Policies pane, double-click Anti-virus and HIPS.
3. Double-click the policy you want to change.

■
If you have download scanning enabled and your users visit a website that contains a threat,
access to the site will be blocked even if it is listed as an authorized website.
■
If you use the web control feature, when you authorize a website that is blocked by your Web
control policy, the website will still be blocked. To allow access to the website, you will need
to exempt it from web control filtering as well as authorize in the anti-virus and HIPS policy.

7.2 Configuring the firewall policy
7.2.1 Basic firewall configuration
7.2.1.1 Set up a basic firewall policy
By default, the firewall is enabled and blocks all non-essential traffic. Therefore, you should
configure it to allow the applications you want to use, and test it before installing it on all computers.
See the Sophos Enterprise Console policy setup guide for detailed advice.
For more information about the default firewall settings, see
http://www.sophos.com/en-us/support/knowledgebase/57757.aspx.
For information about preventing network bridging, see About device control (page 159).
Important: When you apply a new or updated policy to computers, applications that were allowed
before may be blocked briefly until the new policy is fully applied. You should notify your users
about this before you apply new policies.
Note: If you use role-based administration:
■
You must have the Policy setting - firewall right to configure a firewall policy.
■
You cannot edit a policy if it is applied outside your active sub-estate.
For more information about role-based administration, see About roles and sub-estates (page
20).
To set up a basic firewall policy:
1. In the Policies pane, double-click Firewall.
2. Double-click the Default policy to edit it.
The Firewall Policy wizard appears. Follow the instructions on the screen. There is additional
information on some of the options below.
3. On the Configure firewall page, select the type of location:
■
■
Select Single location for computers that are always on the network, for example, desktops.
Select Dual location if you want the firewall to use different settings according to the
location where computers are used, for example, in the office (on the network) and out of
office (off the network). You may want to set up dual location for laptops.
115
Sophos Enterprise Console
4. On the Operational mode page, select how the firewall will handle inbound and outbound
traffic:
Mode
Block inbound and outbound traffic
Description
Default level. Offers the highest security.
Only allows essential traffic through the firewall
and authenticates the identity of applications
using checksums.
To allow applications commonly used in your
organization to communicate through the
firewall, click Trust. For more information, see
About trusting applications (page 122).
Block inbound and allow outbound traffic
Offers a lower security level than Block
inbound and outbound traffic.
Allows your computers to access the network
and internet without you having to create
special rules.
All applications are allowed to communicate
through the firewall.
Monitor
Applies to network traffic the rules that you have
set up. If traffic has no matching rule, it is
reported to the console, and only allowed if it
is outbound.
Enables you to collect information about your
network, and to then create suitable rules
before deploying the firewall to your computers.
For more information, see About using monitor
mode (page 116).
5. On the File and printer sharing page, select Allow file and printer sharing if you want to
allow computers to share local printers and folders on the network.
After you have set up the firewall, you can view firewall events (for example, applications blocked
by the firewall) in the Firewall - Event Viewer. For details, see View firewall events (page 197).
The number of computers with events over a specified threshold within the last seven days is
also displayed on the Dashboard.
7.2.1.2 About using monitor mode
You can enable monitor mode on test computers and use the Firewall Event Viewer to view which
traffic, applications, and processes are being used.
You can then use the Event Viewer to create rules that allow or block reported traffic, applications,
and processes, as described in Create a firewall event rule (page 119).
116
Help
Note: When you create a rule using the Firewall Event Viewer and add it to the firewall policy,
the firewall mode changes from Monitor to Custom.
If you do not want to allow unknown traffic by default, you can use interactive mode.
In interactive mode, the firewall prompts the user to allow or block any applications and traffic for
which it does not have a rule. For details, see About interactive mode (page 121) and the other
topics in the "Working in interactive mode" section.
7.2.1.3 Add and trust an application
Note: If you use role-based administration:
■
You must have the Policy setting - firewall right to configure a firewall policy.
■
You cannot edit a policy if it is applied outside your active sub-estate.

If you want more flexible control of file and printer sharing on your networks (for example,
uni-directional NetBIOS traffic), you can do the following:
1. Allow file and printer sharing on other LANs (Local Area Networks) than those in the LAN
settings list. This allows NetBIOS traffic on those LANs to be processed by the firewall rules.
2. Create high-priority global rules which allow communication to/from hosts with the appropriate
NetBIOS ports and protocols. We recommend that you create global rules to explicitly block
all unwanted file and printer sharing traffic rather than let it be handled by the default rule.
To allow file and printer sharing on other LANs than those in the LAN settings list:
1. Check which firewall policy is used by the group(s) of computers you want to configure.
See Check which policies a group uses (page 33).

7.2.2.3.12
Explanation of ICMP message types
Echo Request, Echo Reply Used to test destination accessibility and status. A host sends an
Echo Request and listens for a corresponding Echo Reply. This
is most commonly done using the ping command.
Destination Unreachable, Sent by a router when it cannot deliver an IP datagram. A datagram
Echo Reply
is the unit of data, or packet, transmitted in a TCP/IP network.
Source Quench
Sent by a host or router if it is receiving data too quickly for it to
handle. The message is a request that the source reduce its rate
of datagram transmission.
Redirect Message
Sent by a router if it receives a datagram that should have been
sent to a different router. The message contains the address to
which the source should direct future datagrams. This is used to
optimize the routing of network traffic.
Router Advertisement,
Router Solicitation
Allow hosts to discover the existence of routers. Routers
periodically broadcast their IP addresses via Router
Advertisement messages. Hosts may also request a router
address by broadcasting a Router Solicitation message to which
a router replies with a Router Advertisement.
Time Exceeded
Sent by a router if the datagram has reached the maximum limit
of routers through which it can travel.
Parameter Problem
Sent by a router if a problem occurs during the transmission of a
datagram such that it cannot complete processing. One potential
source of such a problem is invalid datagram header.
Timestamp Request,
Timestamp Reply
Used to synchronize the clocks between hosts and to estimate
transit time.
Information Request,
Information Reply
Obsolete.These messages were used earlier by hosts to determine
their inter-network addresses, but are now considered outdated
and should not be used.
Address Mask Request,
Address Mask Reply
Used to find the mask of the subnet (i.e. what address bits define
the network). A host sends an Address Mask Request to a router
and receives an Address Mask Reply in return.
7.2.2.4 Firewall rules
7.2.2.4.1 About firewall rules
Global rules
129
Sophos Enterprise Console
Global rules apply to all network communications and to applications even if they have application
rules.
Application rules
You can have one or more rules for an application. You can either use preset rules created by
Sophos or create custom rules to give you fine control over the access allowed for an application.
For information about the settings for the default global and application rules, see
http://www.sophos.com/en-us/support/knowledgebase/57757.aspx.
7.2.2.4.2 About the order in which rules are applied
For connections that use rawsockets, only the global rules are checked.
For connections that do not use rawsockets, various rules are checked, depending on whether
the connection is to a network address that is listed on the LAN tab or not.
If the network address is listed on the LAN tab, the following rules are checked:
■
If the address has been marked as Trusted, all traffic on the connection is allowed with no
further checks.
■
If the address has been marked as NetBIOS, file and printer sharing on any connection that
meets the following criteria is allowed:
Connection
Port
Range
TCP
Remote
137-139 or 445
TCP
Local
137-139 or 445
UDP
Remote
137 or 138
UDP
Local
137 or 138
If the network address is not listed on the LAN tab, other firewall rules are checked in the following
order:
1. Any NetBIOS traffic that has not been allowed using the LAN tab is dealt with according to
the setting of the Block file and printer sharing for other networks check box:
■
If the check box is selected, the traffic is blocked.
■
If the check box is cleared, the traffic is processed by the remaining rules.
2. The high-priority global rules are checked, in the order in which they are listed.
3. If the connection has not already had rules applied to it, the application rules are checked.
4. If the connection has still not been handled, the normal-priority global rules are checked, in
the order in which they are listed.
5. If no rules have been found to handle the connection:
■
130
In Allow by default mode, the traffic is allowed (if it is outbound).
Help
■
In Block by default mode, the traffic is blocked.
■
In Interactive mode, the user is asked to decide.
Note: If you have not changed the working mode, the firewall will be in Block by default
mode.
7.2.2.4.3 About local network detection
You can assign the local network for a computer to firewall rules.
When the firewall starts, it determines the computer's local network, and then monitors for any
changes whilst it is running. If any change is detected, the firewall updates any local network rules
with the new local network address range.
Caution: We strongly advise caution when using local network rules as part of secondary
configurations. If the computer is a laptop, and it is used out of the office, it may connect to an
unknown local network. If this happens, firewall rules in the secondary configuration that use the
local network as an address may inadvertently allow unknown traffic.

7.2.2.5 Location awareness
7.2.2.5.1 About location awareness
Location awareness is a feature of Sophos Client Firewall that assigns a firewall configuration to
each network adapter on a computer, depending on the current location of the computer's network
adapters.
The most common scenario in which this feature is used is where an employee has a company
laptop and works from home. They are using two network connections simultaneously:
■
For work use, they connect to the office network through a VPN client and a virtual network
adapter.
■
For personal use, they connect to their ISP through a network cable and a physical network
adapter.
137
Sophos Enterprise Console
In this scenario, you need the office configuration to be applied to the virtual office connection
and the non-office, generally more restrictive, configuration to be applied to the non-office ISP
connection.
Note: The non-office configuration requires sufficient rules to allow the "virtual" office connection
to be established.
7.2.2.5.2 About setting up location awareness
1. Define the list of gateway MAC addresses or domain names of your primary locations. Typically,
these are your office networks.
2. Create the firewall configuration to be used for your primary locations. Typically, this
configuration is less restrictive.
3. Create a secondary firewall configuration. Typically, this configuration is more restrictive.
4. Choose a configuration to apply.
Depending on the detection method you are using, the firewall obtains the DNS or gateway
address for each computer's network adapters, and then matches it against your list of addresses.
■
If any of the addresses in your list matches the address of a network adapter, the adapter is
assigned the configuration for the primary location.
■
If none of the addresses in your list matches the address of a network adapter, the adapter is
assigned the policy for the secondary location.
Important: The secondary configuration switches from Interactive mode to Block by default
mode on a computer when both the following conditions are met:
■
Both locations are active.
■
The primary configuration is not interactive.
7.2.2.5.3 Define your primary locations
1. Double-click the firewall policy you want to change.
2. On the Welcome page of the Firewall Policy wizard, click Advanced firewall policy.
3. Under Configurations, click Configure next to the location for which you want to configure
the firewall.
4. Click the Location detection tab.
5. Under Detection method, click Configure next to the method that you want to use to define
your primary locations:
Identify location by DNS
You create a list of domain names and expected
IP addresses that correspond to your primary
locations.
Identify location by gateway MAC address
You create a list of gateway MAC addresses that
correspond to your primary locations.
6. Follow the instructions on the screen.
7.2.2.5.4
Create a secondary configuration
1. Double-click the firewall policy you want to change.

the firewall section.
Caution: We strongly advise caution when using local network rules as part of secondary
configurations. If the computer is a laptop, and it is used out of the office, it may connect to an
unknown local network. If this happens, firewall rules in the secondary configuration that use the
local network as an address may inadvertently allow unknown traffic.

7.2.2.6 Firewall reporting
7.2.2.6.1 About firewall reporting
By default, the firewall on an endpoint computer reports state changes, events, and errors to
Enterprise Console.
Firewall state changes
The firewall regards the following as state changes:
■
Changes to the working mode
■
Changes to the software version
■
Changes to whether the firewall is configured to allow all traffic
■
Changes to whether the firewall complies with policy
139
Sophos Enterprise Console
When you are working in interactive mode, your firewall configuration may deliberately differ from
the policy applied by Enterprise Console. In that case, you can choose not to send "differs from
policy" alerts to Enterprise Console when you make changes to certain parts of your firewall
configuration.
For more information, see Turn reporting of local changes on or off (page 140).
Firewall events
An event is when the endpoint computer's operating system, or an unknown application on the
endpoint computer, tries to communicate with another computer over a network connection.
You can prevent the firewall from reporting events to Enterprise Console.
For more information, see Turn off reporting of unknown network traffic (page 140).
7.2.2.6.2
Turn reporting of local changes on or off
Note: If you use role-based administration:
■
You must have the Policy setting - firewall right to configure a firewall policy.
■
You cannot edit a policy if it is applied outside your active sub-estate.
For more information, see About roles and sub-estates (page 20).
If the firewall configuration on endpoint computers differs from policy, you can turn reporting of
local changes off.
Turning reporting of local changes off stops the firewall sending "differs from policy" alerts to
Enterprise Console about changes made to the global rules, applications, processes, or checksums.
You may want to do this, for example, when the endpoint computers are in interactive mode,
since these are settings that can be changed by using the learning dialogs.
If the firewall configuration on endpoint computers is intended to conform to policy, you should
turn reporting of local changes on.
To turn reporting of local changes off:
1. Double-click the firewall policy you want to change.
2. On the Welcome page of the Firewall Policy wizard, click Advanced firewall policy.
3. Under Configurations, click Configure next to the location for which you want to configure
the firewall.
4. Click the General tab.

7.3 Configuring the application control policy
7.3.1 About application control
Enterprise Console enables you to detect and block "controlled applications", that is, legitimate
applications that are not a security threat, but that you decide are unsuitable for use in your office
environment. Such applications may include instant messaging (IM) clients, Voice over Internet
Protocol (VoIP) clients, digital imaging software, media players, or browser plug-ins.
Note: This option applies only to Sophos Endpoint Security and Control for Windows.
Applications can be blocked or authorized for different groups of computers with complete flexibility.
For example, VoIP can be switched off for office-based desktop computers, yet authorized for
remote computers.
The list of controlled applications is supplied by Sophos and updated regularly. You cannot add
new applications to the list, but you can submit a request to Sophos to include a new legitimate
application you would like to control on your network. For details, see Sophos support
knowledgebase article 35330 (http://www.sophos.com/en-us/support/knowledgebase/35330.aspx).
This section describes how to select the applications you want to control on your network and set
up scanning for controlled applications.
Note: If you use role-based administration:
■
You must have the Policy setting - application control right to configure an application
control policy.
■
You cannot edit a policy if it is applied outside your active sub-estate.
For more information about role-based administration, see About roles and sub-estates (page
20).
Application control events
When an application control event occurs, for example, a controlled application has been detected
on the network, the event is written in the application control event log that can be viewed from
Enterprise Console. For details, see View application control events (page 195).
The number of computers with events over a specified threshold within the last seven days is
displayed on the Dashboard.
You can also set up alerts to be sent to your chosen recipients when an application control event
has occurred. For details, see Set up application control alerts and messages (page 189).

Note: Your anti-virus and HIPS policy settings determine which files are scanned (that is, the
extensions and exclusions).
If you want to remove controlled applications found on your networked computers, follow the
instructions in Uninstall controlled applications you do not want (page 144).
You can also have alerts sent to particular users if a controlled application is found on any of the
computers in the group. For instructions, see Set up application control alerts and messages
(page 189).
7.3.4 Uninstall controlled applications you do not want
Before you uninstall controlled applications, ensure that on-access scanning for controlled
applications is disabled. This type of scanning blocks the programs used to install and uninstall
applications, so it may interfere with uninstallation.
You can remove an application in one of two ways:
■
Go to each computer and run the uninstaller for that product.You can usually do this by opening
the Windows Control Panel and using Add/Remove Programs.
■
At the server, use your usual script or administration tool to run the uninstaller for that product
on your networked computers.
Now you can enable on-access scanning for controlled applications.
7.4 Configuring the data control policy
7.4.1 About data control

your license. For more information, see

Help
Data control enables you to reduce accidental data loss from workstations by monitoring and
restricting the transfer of files containing sensitive data. You do this by creating data control rules
and then adding the rules to the Data control policies.
You can monitor and control the transfer of files to specified storage devices (e.g. removable
storage device or optical drive) or by specified applications (e.g. email client or web browser).
To enable you to quickly define and roll out a data control policy, SophosLabs maintain a library
of sensitive data definitions (Content Control Lists). The main focus for this library is personally
identifiable information, but it also covers other common data structures. You can use Content
Control Lists in Enterprise Console, as described further in this section.
7.4.2 How does data control work?
Data control identifies accidental data loss that is typically caused by employees mishandling
sensitive data. For example, a user sends a file containing sensitive data home via web-based
email.
Data control enables you to monitor and control the transfer of files from computers to storage
devices and applications connected to the internet.
■
Storage devices: Data control intercepts all files copied onto monitored storage devices using
Windows Explorer (this includes the Windows desktop). However, direct saves from within
applications, such as Microsoft Word, or transfers made using the command prompt are not
intercepted.
It is possible to force all transfers onto monitored storage devices to be made using Windows
Explorer by using either the Allow transfer on acceptance by user and log event action or
the Block transfer and log event action. In either case, any attempt to save directly from
within an application or transfer files using the command prompt are blocked by data control,
and a desktop alert is displayed to the user requesting that they use Windows Explorer to
complete the transfer.
When a data control policy only contains rules with the Allow file transfer and log event
action, direct saves from within applications and transfers using the command prompt are not
intercepted. This behavior enables users to use storage devices without any restrictions.
However, data control events are still logged for transfers made using Windows Explorer.
Note: This restriction does not apply to application monitoring.
■
Applications: To ensure only file uploads by users are monitored, some system file locations
are excluded from data control monitoring. This significantly reduces the risk of data control
events being generated by applications opening configuration files as opposed to users
uploading files.
Important: If you experience erroneous events generated by an application opening
configuration files, the problem can usually be solved by adding custom location exclusions
or by configuring a data control rule to be less sensitive. For more information, see support
knowledgebase article 113024
(http://www.sophos.com/en-us/support/knowledgebase/113024.aspx).
Note: If you exclude remote files from on-access scanning in the anti-virus and HIPS policy,
data control will not scan files uploaded or attached from a network location using a monitored
application, for example, an email client, a web browser, or an instant messaging (IM) client.
This is because data control uses the same set of exclusions as the Sophos Anti-Virus
145
Sophos Enterprise Console
on-access scanner, so if remote file scanning is disabled, it will not send any remote files for
a data control check. This restriction does not apply to storage device monitoring. For
information about configuring on-access scanning exclusions, see Exclude items from on-access
scanning (page 93).
Data control policies
Data control enables you to monitor and control the transfer of files by defining data control policies
and applying them to groups of computers on your network.
Important: Data control is not supported on Windows 2008 Server Core and must be disabled
on computers running this operating system. To exclude Windows 2008 Server Core computers
from data control scanning, put them in a group that has a data control policy with data control
scanning disabled. For details, see Turn data control on or off (page 149).
Data control policies include one or more rules that specify conditions and actions to be taken
when the rule is matched. A data control rule can be included in multiple policies.
When a data control policy contains several rules, a file that matches any of the rules in the data
control policy violates the policy.
Data control rule conditions
The data control rule conditions include destination, file name and extension, file type, or file
content.
Destination includes devices (for example, removable storage devices, such as USB flash drives)
and applications (for example, internet browsers and email clients).
The matching of file content is defined using a Content Control List. This is an XML based
description of structured data. SophosLabs provide an extensive set of Content Control Lists
which can be used within your data control rules.
For more information about data control rules and conditions applied to files, see About data
control rules (page 147).
For more information about Content Control Lists (CCLs) that define file content, see About
Content Control Lists (page 148).
146
Help
Figure 2: Data Control
Data control rule actions
When data control detects all the conditions specified in a rule, the rule is matched, and data
control takes the action specified in the rule and logs the event.You can specify one of the following
actions:
■
Allow file transfer and log event
■
Allow transfer on acceptance by user and log event
■
Block transfer and log event
If a file matches two data control rules that specify different actions, the rule that specifies the
most restrictive action is applied. Data control rules that block file transfer take priority over the
rules that allow file transfer on user acceptance. Rules that allow file transfer on user acceptance
take priority over the rules that allow file transfer.
By default, when the rule is matched and file transfer is blocked or user confirmation of file transfer
is required, a message is displayed on the endpoint computer's desktop. The rule that has been
matched is included in the message. You can add your own custom messages to the standard
messages for user confirmation of file transfer and for blocked file transfer. For more information,
see Set up data control alerts and messages (page 190).
7.4.3 About data control rules
Data control rules specify conditions for data control scanning to detect, actions to be taken if
rules are matched, and any files to be excluded from scanning.
You can create your own rules or use the sample rules provided. We provide a number of
preconfigured data control rules that you can use unmodified or customize to your own needs.
These rules are provided as examples only and are not updated.
147
Sophos Enterprise Console
There are two types of data control rule: file matching rule and content rule.
File matching rules
A file matching rule specifies action to be taken if a user attempts to transfer a file with the specified
file name or of the specified file type (true file type category, e.g. a spreadsheet) to the specified
destination, for example, block the transfer of databases to removable storage devices.
Data control includes true file type definitions for over 150 different file formats. We may add
additional true file types from time to time. The newly added types will be automatically added to
any data control rules that use the relevant true file type category.
File types not covered by a true file type definition can be identified using their file extensions.
Content rules
A content rule is a rule that contains one or more Content Control Lists and specifies action to be
taken if a user attempts to transfer data that matches all the Content Control Lists in the rule to
the specified destination.
7.4.4 About Content Control Lists
A Content Control List (CCL) is a set of conditions that describe structured file content. A Content
Control List may describe a single type of data (for example, a postal address or social security
number) or a combination of data types (for example, a project name near to the term
"confidential").
You can use SophosLabs Content Control Lists that are provided by Sophos or create your own
Content Control Lists.
SophosLabs Content Control Lists provide expert definitions for common financial and personally
identifiable data types, for example, credit card numbers, social security numbers, postal addresses,
or email addresses. Advanced techniques, such as checksums, are used in SophosLabs Content
Control Lists to increase the accuracy of sensitive data detection.
You cannot edit SophosLabs Content Control Lists, but you can submit a request to Sophos to
create a new SophosLabs Content Control List. For details, see Sophos support knowledgebase
article 51976 (http://www.sophos.com/en-us/support/knowledgebase/51976.aspx).
Note: Double-byte characters (for example, Japanese or Chinese characters) are not officially
supported in the current version of Content Control Lists. However, you can enter double-byte
characters in the Content Control List editor.
Setting up the quantity for SophosLabs Content Control Lists
Most SophosLabs Content Control Lists have quantity assigned to them.
A quantity is the volume of the Content Control List key data type that must be found in a file
before the Content Control List is matched. You can edit the quantity of a SophosLabs Content
Control List in a content rule that includes that Content Control List.
Using quantity, you can fine-tune your data control rules and avoid blocking documents that do
not contain sensitive information (for example, a document containing one postal address or one
or two telephone numbers, possibly in the letterhead or signature). If you search for a single postal
148
Help
address, thousands of documents may match the rule and trigger a data control event. However,
if you want to prevent the loss of a customer list, you may want to only detect the transfer of
documents containing, for example, more than 50 postal addresses. In other cases, however, it
may be advisable to search for a single instance of content, for example, a credit card number.
7.4.5 About data control events
When a data control event occurs, for example, the copying of a file containing sensitive data to
a USB flash drive, the event is sent to Enterprise Console and can be viewed in the Data Control
- Event Viewer. The event is also logged locally on the endpoint computer and can be viewed,
with the appropriate permissions, in Sophos Endpoint Security and Control.
Note: An endpoint computer can send to Enterprise Console a maximum of 50 data control
events per hour. All events are logged locally on the endpoint computer.
In the Data Control - Event Viewer dialog box, you can use filters to display only the events you
are interested in. You can also export the list of data control events to a file. For details, see View
data control events (page 196) and Export the list of events to a file (page 204).
The number of computers with data control events over a specified threshold within the last seven
days is displayed on the Dashboard. For information on how to set up the threshold, see Configure
the Dashboard (page 56).
You can also set up alerts to be sent to your chosen recipients when a data control event has
occurred. For details, see Set up data control alerts and messages (page 190).
7.4.6 Turn data control on or off

of expression A and 1 match of expression B, or 1 match of expression B and 5 matches of
expression C.
Click OK.
The new Content Control List appears in the Content Control List Management dialog box.
Regular expression example
(?i)\b[a-ceghj-npr-tw-z][a-ceghj-npr-tw-z]\s?\d{2}\s?\d{2}\s?\d{2}\s?[abcd]?\b
This regular expression matches UK National Insurance numbers, for example, AA 11 11 11 A.
(?i)
Makes the match case-insensitive.
\b
Matches a boundary between a word character and a non-word character.
[a-ceghj-npr-tw-z]
Matches any single character in the range of characters (A to C E G H J to N
P R to T W to Z).
?
Matches the preceding element zero or one time.
\s?
Matches zero or one whitespace.
\d{2}
Matches two digits.
[abcd]
Matches any single character from the list (A, B, C, or D).
Now you can add the new Content Control List to a content rule.

7.5 Configuring the device control policy
7.5.1 About device control
Note: This feature is not included with all licenses. If you want to use it, you might need to change
your license. For more information, see
http://www.sophos.com/en-us/products/complete/comparison.aspx.
Important: Sophos device control should not be deployed alongside device control software
from other vendors.
Device control enables you to prevent users from using unauthorized external hardware devices,
removable storage media, and wireless connection technologies on their computers. This can
help to significantly reduce your exposure to accidental data loss and restrict the ability of users
to introduce software from outside of your network environment.
Removable storage devices, optical disk drives, and floppy disk drives can also be set to provide
read-only access.
Using device control, you can also significantly reduce the risk of network bridging between a
corporate network and a non-corporate network. The Block bridged mode is available for both
wireless and modem types of device. The mode works by disabling either wireless or modem
network adapters when an endpoint is connected to a physical network (typically through an
Ethernet connection). Once the endpoint is disconnected from the physical network, the wireless
or modem network adapters are seamlessly re-enabled.
By default, device control is turned off and all devices are allowed.
If you want to enable device control for the first time, we recommend that you:
■
Select device types to control.
159
Sophos Enterprise Console
■
Detect devices without blocking them.
■
Use device control events to decide which device types to block and which, if any, devices
should be exempt.
■
Detect and block devices or allow read-only access to storage devices.
For more information about the recommended settings for device control, see the Sophos
Enterprise Console policy setup guide.
Note: If you use role-based administration:
■
You must have the Policy setting - device control right to configure a device control policy.
■
You cannot edit a policy if it is applied outside your active sub-estate.
For more information, see About roles and sub-estates (page 20).
7.5.2 About device control events
When a device control event occurs, for example, a removable storage device has been blocked,
the event is sent to Enterprise Console and can be viewed in the Device Control - Event Viewer
dialog box.
In the Device Control - Event Viewer dialog box, you can use filters to display only the events
you are interested in. You can also export the list of device control events to a file. For details,
see View device control events (page 196) and Export the list of events to a file (page 204).
You can use device control events to add exemptions for specific devices or device models to
the device control policies. For more information about exempting devices, see Exempt a device
from a single policy (page 164) or Exempt a device from all policies (page 163).
The number of computers with device control events over a specified threshold within the last
seven days is displayed on the Dashboard. For information on how to set up the threshold, see
Configure the Dashboard (page 56).
You can also set up alerts to be sent to your chosen recipients when a device control event has
occurred. For details, see Set up device control alerts and messages (page 191).
7.5.3 What types of device can be controlled?
Device control enables you to block the following types of device: storage, network, short range,
and media.
Storage
■
Removable storage devices (for example, USB flash drives, PC Card readers, and external
hard disk drives)
■
Optical media drives (CD-ROM/DVD/Blu-ray drives)
■
Floppy disk drives
■
Secure removable storage devices (for example, hardware-encrypted USB flash drives)
For a list of supported secure removable storage devices, see Sophos support knowledgebase
article 63102 (http://www.sophos.com/en-us/support/knowledgebase/63102.aspx).
160
Help
Tip: Using the secure removable storage category, you can easily allow the use of supported
secure removable storage devices while blocking other removable storage devices.
Network
■
Modems
■
Wireless (Wi-Fi interfaces, 802.11 standard)
For network interfaces, you can also select the Block bridged mode that helps to significantly
reduce the risk of network bridging between a corporate network and a non-corporate network.
The mode works by disabling either wireless or modem network adapters when an endpoint is
connected to a physical network (typically through an Ethernet connection). Once the endpoint
is disconnected from the physical network, the wireless or modem network adapters are seamlessly
re-enabled.
Short Range
■
Bluetooth interfaces
■
Infrared (IrDA infrared interfaces)
Device control blocks both internal and external devices and interfaces. For example, a policy
which blocks Bluetooth interfaces will block both of the following:
■
The built-in Bluetooth interface in a computer
■
Any USB-based Bluetooth adapters plugged into the computer
Media
■
MTP/PTP
This includes mobile phones, tablets, digital cameras, media players and other devices that
connect to a computer using Media Transfer Protocol (MTP) or Picture Transfer Protocol (PTP).
7.5.4 Select device types to control

7.6 Configuring the full disk encryption policy
7.6.1 About full disk encryption
Note: This feature is not included with all licenses. If you want to use it, you might need to change
your license. For more information, see
http://www.sophos.com/en-us/products/complete/comparison.aspx.
Full disk encryption protects the data on endpoint computers from being read or changed by
unauthorized persons.Volumes on disks are encrypted transparently. Users do not need to decide
what data is to be encrypted. Encryption and decryption are performed in the background.
By default, computers protected by full disk encryption run the Power-on Authentication (POA)
before the operating system starts. After the user has logged on at the Power-on Authentication,
the operating system starts and the user is logged on to Windows.
For convenient access, full disk encryption offers several features that aid IT operations on endpoint
computers:
■
The Power-on Authentication can be temporarily deactivated for Wake on LAN, for example
to facilitate patch management.
■
Normally, the first user who logs on to an endpoint computer after the encryption software has
been installed, activates the Power-on Authentication. You can configure Windows accounts
for logon to endpoint computers without activating the Power-on Authentication. This helps
members of the IT team, for example, rollout operators. With the Windows accounts you specify
in the full disk encryption policy as Power-on Authentication exceptions, they can log on to
new computers for installation and verification tasks before end users log on and activate the
Power-on Authentication.
■
You can configure a POA user account to a member of the IT team to log on to endpoint
computers for administrative tasks when the Power-on Authentication is already active.
For recovery on computers protected by full disk encryption, the following logon recovery methods
are available:
■
Challenge/Response helps users who cannot log on to their computers or access encrypted
data. A Challenge/Response procedure involves the assistance of a help desk. During the
Challenge/Response procedure, the user provides a challenge code generated on the endpoint
computer to the help desk officer. The help desk officer then generates a response code that
authorizes the user to perform a specific action on the computer. For more information, see
Recover access with Challenge/Response (page 217).
■
With Local Self Help users who have forgotten their password can log on at their computer
without the assistance of a help desk. Users log on by answering predefined questions in the
Power-on Authentication. Local Self Help reduces the number of help desk calls and allows
help desk staff to concentrate on more complex support requests. For more information, see
Recover access with Local Self Help (page 218).
Important: Do not delete from the console computers that have been encrypted. Encryption
recovery may not be possible in this case.
For more information about the recommended settings for full disk encryption, see the Sophos
Enterprise Console policy setup guide.
166
Help
For information about viewing events logged for computers protected by full disk encryption, see
View encryption events (page 197).
7.6.2 Configure full disk encryption
Caution: If you are installing the Sophos encryption software for the first time, we strongly
recommend that you enable and test each setting step-by-step.
If you use role-based administration:
■
You must have the Policy setting - full disk encryption right to edit a full disk encryption
policy.
■
You cannot edit a policy if it is applied outside your active sub-estate.
For more information, see About roles and sub-estates (page 20).
By default, full disk encryption is not enabled.
To enable and configure full disk encryption:
1. Check which full disk encryption policy is used by the group or groups of computers you want
to configure.
See Check which policies a group uses (page 33).
2. In the Policies pane, double-click Full disk encryption. Then double-click the policy you want
to change.
The Full disk encryption dialog box is displayed.
3. Under Volumes to encrypt, specify which volumes you want to encrypt by selecting the
relevant check box(es):
■
■
Boot volumes
Non-boot volumes
4. Select Fast initial encryption (only encrypts used space on a drive) to reduce the time
needed for initial encryption on endpoint computers.
Note: The fast initial encryption mode leads to a less secure state if a disk has been in use
before encryption is applied. Unused sectors may still contain data.
5. Click OK.
When you assign the full disk encryption policy with these settings to a group of computers with
the latest Sophos encryption software installed, the encryption process starts once the policy is
received. The user can carry on working.
Note: To decrypt computers, clear the relevant options under Volumes to encrypt and assign
the policy to the group of computers to be decrypted. Users are then allowed to manually decrypt
the respective drives.

The Exceptions dialog box is displayed.
b) Click Add, enter the User name and the Computer or Domain Name of the relevant
Windows account(s) and click OK.
Note: In the fields User name and Computer or Domain Name you can use wildcards
as the first or last character. In the User name field, the ? character is not allowed. In the
Computer or Domain Name field, the characters / \ [ ] : ; | = , + ? < > " are not allowed.
5. Select Fingerprint, to enable users to log on with Lenovo Fingerprint Reader.
6. To specify a user who can log on to the endpoint computer for administrative tasks when the
Power-on Authentication is already active, select POA user and click the Configure button.
a) In the Configure POA User dialog box, enter a logon name of your choice for the POA
user in the User name field. You can freely define the logon name, with the following
exceptions:
Note: In the User name field, the characters / \ [ ] : ; | = , + ? < > " * are not allowed.
Note: When setting up and entering logon names for POA users in Japanese, you have
to use Romaji (Roman) characters to successfully log on at the POA.
b) Click the Set button next to the Password field.
168

select Temporary deactivation (for Wake on LAN).
For more information, see Configure temporary POA deactivation for Wake on LAN (page 169)
8. In the Full Disk Encryption dialog box, click OK.
Note: If you clear Enable Power-on Authentication, you are prompted to confirm if you want
to disable Power-on Authentication or not. For security reasons, we strongly recommend that you
click No to keep Power-on Authentication enabled. Deactivating Power-on Authentication reduces
system security to Windows logon security and increases the risk of unauthorized access to
encrypted data.
7.6.4 Configure temporary POA deactivation for Wake on LAN
If you use role-based administration:
■
You must have the Policy setting - full disk encryption right to edit a full disk encryption
policy.
■
You cannot edit a policy if it is applied outside your active sub-estate.
■
In the full disk encryption policy, the Enable Power-on Authentication field must be selected.
For more information, see About roles and sub-estates (page 20).
By default, computers who use a full disk encryption policy are protected by Power-on
Authentication. You can temporarily deactivate the Power-on Authentication for Wake on LAN,
for example to facilitate patch management. Wake on LAN is activated by running the scheduling
script SGMCMDIntn.exe on the endpoint computer.
Note: Deactivating the POA - even for a limited number of boot processes - reduces the level of
security of your system.
1. Check which full disk encryption policy is used by the group or groups of computers you want
to configure.
See Check which policies a group uses (page 33).
2. In the Policies pane, double-click Full disk encryption. Then double-click the policy you want
to change.
The Full Disk Encryption dialog box is displayed.
3. Under Power-on Authentication (POA), make sure that the Enable Power-on Authentication

LAN, for example for software updates.
7. In the Auto logon limit field, specify how often the computer is restarted without authentication
through the Power-on Authentication during Wake on LAN.
Note: We recommend that you allow three more restarts than necessary in case of any
problems.
8. Click OK.
7.6.4.1 Wake on LAN example
For a software rollout planned between 03:00 am and 06:00 am on a specific date, two restarts
are required. The local software rollout agent must be able to log on to Windows.
In the full disk encryption policy, under Temporary deactivation (for Wake on LAN) you configure
the following settings:
Policy setting
Value
Start
Day before software rollout, 12:00 noon
End
Day of software rollout 06:00 am
Allow Windows logon during this time
Yes
Auto logon limit
5
As the auto logon limit is set to 5 the endpoint computer starts 5 times without authentication
through POA.
Note: In this example, the autologon limit is set to 5 as we recommend that you allow three more
restarts than necessary in case of any problems.
By setting the start time to 12:00 noon on the day before the software rollout, you make sure that
the scheduling script SGMCMDIntn.exe is started in time and that the Wake on LAN process
starts no later than 03:00 am on the day of the software rollout.
The following two commands have to be created for the scheduling script SGCMDIntn.exe by the
software rollout team:
■
Start on the day before software rollout, 12:15 am, SGMCMDIntn.exe -WOLstart
■
Start on the day after the software rollout, 09:00 am, SGMCMDIntn.exe -WOLstop
The date of the software rollout script is defined as the day of the rollout, 03:00 am. Wake on LAN
can explicitly be deactivated again at the end of the script with SGMCMDIntn.exe -WOLstop.
All endpoint computers that log on before the date specified for Start and connect to the rollout
servers receive the new policy and the scheduling commands.

7.7 Configuring the tamper protection policy
7.7.1 About tamper protection
Tamper protection enables you to prevent unauthorized users (local administrators and users
with limited technical knowledge) and known malware from uninstalling Sophos security software
or disabling it through the Sophos Endpoint Security and Control interface.
Note: Tamper protection is not designed to protect against users with extensive technical
knowledge. Nor does it protect against malware which has been specifically designed to subvert
the operating system to avoid detection. This type of malware is only detected by scanning for
threats and suspicious behavior. (For more information, see About the anti-virus and HIPS policy
(page 86).)
173
Sophos Enterprise Console
After you enable tamper protection and create a tamper-protection password, a member of the
SophosAdministrator group on the endpoint who does not know the password will not be able to:
■
Re-configure on-access scanning or suspicious behavior detection settings in Sophos Endpoint
Security and Control.
■
Disable tamper protection.
■
Uninstall the Sophos Endpoint Security and Control components (Sophos Anti-Virus, Sophos
Client Firewall, Sophos AutoUpdate, or Sophos Remote Management System).
■
Uninstall Sophos Disk Encryption.
If you want to enable SophosAdministrators to perform these tasks, you must provide them with
the tamper protection password so that they can authenticate themselves with tamper protection
first.
Tamper protection does not affect members of the SophosUser and SophosPowerUser groups.
When tamper protection is enabled, they will be able to perform all tasks that they are usually
authorized to perform, without the need to enter the tamper protection password.
Note: If you use role-based administration:
■
You must have the Policy setting - tamper protection right to configure a tamper protection
policy.
■
You cannot edit a policy if it is applied outside your active sub-estate.
For more information, see About roles and sub-estates (page 20).
Tamper protection events
When a tamper protection event occurs, for example, an unauthorized attempt to uninstall Sophos
Anti-Virus from an endpoint computer has been prevented, the event is written in the event log
that can be viewed from Enterprise Console. For details, see View tamper protection events (page
198).
There are two types of tamper protection event:
■
Successful tamper protection authentication events, showing the name of the authenticated
user and the time of authentication.
■
Failed attempts to tamper, showing the name of the targeted Sophos product or component,
the time of the attempt, and the details of the user responsible for the attempt.
7.7.2 Turn tamper protection on or off
If you use role-based administration:
■
You must have the Policy setting - tamper protection right to configure a tamper protection
policy.

7.8 Configuring the patch policy
7.8.1 About patch assessment
Note: This feature is not included with all licenses. If you want to use it, you might need to change
your license. For more information, see
http://www.sophos.com/en-us/products/complete/comparison.aspx.
Enterprise Console enables you to check that your computers have the most up-to-date security
patches installed.
175
Sophos Enterprise Console
SophosLabs provides ratings that help you determine the most critical security patch issues so
that you can resolve them quickly. SophosLabs ratings take the latest exploits into account and
therefore may differ from a vendor's severity level.
Before using patch, you must install the patch agent on your networked computers so that they
can perform patch assessments and communicate status to Enterprise Console. You can install
this using the Protect Computers Wizard. See Protect computers automatically (page 52).
This section assumes that you have installed the patch agent.
Note: If you use role-based administration:
■
You must have the Policy setting - patch right to configure a patch policy.
■
You cannot edit a policy if it is applied outside your active sub-estate.
For more information about role-based administration, see About roles and sub-estates (page
20).
7.8.2 How does patch assessment work?
Patch assessment is disabled in the default policy. Once patch assessment is enabled, computers
begin an assessment. This can take several minutes. Subsequent assessments occur at the
interval set in policy, which is daily by default.
Note: If computers run an assessment before Enterprise Console has downloaded patch data
from Sophos for the first time, the Patch Event viewer displays no results. The download can take
several hours. To check if this has completed, see the Patch updates field in Events > Patch
Assessment Events.
If the patch agent cannot update from Enterprise Console, for any reason, it will continue to assess
computers against the previously downloaded patch detections.
Computers are only assessed for security patches on software that is installed on the computer.
If a new patch is released that supersedes an older patch, then patch assessment will no longer
check for the presence of the older patch. Only the new patch will be assessed.
7.8.2.1 What are superseded patches?
If a vendor releases a patch that replaces an earlier patch, the new patch is called a superseding
patch. The patch it replaces is referred to as the superseded patch.
Sophos recommends you install the superseding patch to keep your computers up-to-date.
Example: If you search for virusX and see that the fix for the virus is available in patch P01, which
is superseded by patch P02, Sophos recommends you install P02.
7.8.3 About patch assessment events
When a patch assessment event occurs, for example, a computer is missing a patch, the event
is sent to Enterprise Console and can be viewed in the Patch Assessment - Event Viewer.
In the Patch Assessment - Event Viewer, you can use filters to display only the events you are
interested in. You can also export the list of patch assessment events to a file. For details, see
View patch assessment events (page 200) and Export the list of events to a file (page 204).
176
Help
7.8.4 Turn patch assessment on or off

7.9 Configuring the web control policy
7.9.1 About the web control policy
Note: This feature is not included with all licenses. If you want to use it, you might need to change
your license. For more information, see
http://www.sophos.com/en-us/products/complete/comparison.aspx.
By default, the web control policy is turned off in Enterprise Console. Selecting Enable web
control allows you to choose one of the following policy options:
■
Inappropriate Website Control: This basic web control option includes 14 essential site
categories. It is designed to protect users from visiting websites for which your organization
177
Sophos Enterprise Console
could be legally liable. For more information, see About Inappropriate Website Control (page
178).
■
Full Web Control: This option applies a comprehensive, full-featured policy that covers more
than 50 website categories. It requires a Sophos Web Appliance, Sophos Management
Appliance, or Sophos UTM appliance (version 9.2 or later) to synchronize with endpoints to
distribute policy updates and collect web activity data. For more information, see About Full
Web Control (page 182).
When using Inappropriate Website Control, you can either edit an existing web control policy, or
create a new policy. For more information, see Create a policy (page 38). You can set the various
site categories to “Block,” “Warn,” or “Allow.” Web control status and web events are displayed
in Enterprise Console. For more information about web events, see View web events (page 202).
If, instead, you are using the Full Web Control policy, Enterprise Console requires the location of
the Web, UTM, or Management Appliance from which the full web-filtering policy is configured,
together with a shared key to secure communication between the appliance and Enterprise
Console. When the Full Web Control policy is selected, most of the reporting and monitoring is
shifted to the appliance; however, websites scanned and assessed by Sophos Endpoint Security
and Control's live URL-filtering (Web Protection (page 106)) are displayed in Enterprise Console
as web events.
For more information about web control, see the Endpoint web control overview guide.
Note: If you use role-based administration:
■
You must have the Policy setting - web control right to edit a web control policy.
■
You cannot edit a policy if it is applied outside your active sub-estate.
For more information about role-based administration, see About roles and sub-estates (page
20).
7.9.2 Inappropriate Website Control
7.9.2.1 About Inappropriate Website Control
Note: This feature is not included with all licenses. If you want to use it, you might need to
customize your license. For more information, see
http://www.sophos.com/en-us/products/complete/comparison.aspx.
With this basic form of website control, you can filter the web activity of users, based on 14 website
categories. There is a default action for each category (described in About website categories
(page 179)), but, if necessary, you can select a different action, as described in Select a website
category action (page 181).
Users can be blocked from visiting restricted websites. An event is triggered that is shown to the
user and sent to Enterprise Console.
Alternatively, users can be warned by means of a notification when visiting controlled websites;
even if the user does not proceed, a warning event is triggered. If the user proceeds and views
a site despite the warning, a second event is triggered and sent to Enterprise Console.
Note: Although HTTP and HTTPS sites are both filtered in all supported web browsers, user
notifications are different, depending on whether the URL is HTTP or HTTPS. With HTTP sites,
users see notification pages for sites in categories set to “Block” or “Warn.” For HTTPS, users
178
Help
only see “Block” notifications, and they are displayed as a balloon tip in the Windows System
Tray. HTTPS “Warn” actions are neither displayed to the user nor are they logged. Instead, users
are allowed to continue to the requested page, and the event is logged as a “Proceed” in Enterprise
Console.
If you select the “Allow” action for a website category, users can access all websites within this
category, unless website exceptions are specified. “Allow” events are not logged when
Inappropriate Website Control is selected.
Note: Allowed sites are still scanned and assessed by Sophos Endpoint Security and Control's
live URL-filtering (Web protection) feature.
7.9.2.2 Turn on Inappropriate Website Control
Perform the following steps to turn on web control in Enterprise Console and use Inappropriate
Website Control.
Note: If you use role-based administration:
■
You must have the Policy setting - web control right to edit a web control policy.

domain names. You can also edit existing website entries, and remove websites from a list.
Note: If there are conflicting or overlapping entries in the 'Block' and 'Allow' lists, the entries in
the Block list will always take precedence. For example, if the same IP address is included in the
Block list and the Allow list, the website is blocked. Furthermore, if a domain is included in the
Block list, but a subdomain of that same domain is included in the Allow list, the Allow entry is
ignored, and the domain and all of its subdomains are blocked.
To add a website exception:
1. On the Website Exceptions tab, click the Add button next to the Websites to Allow or
Websites to Block text box.
2. In the Add Website to Allow dialog box, click Domain name, IP address with subnet mask,

Help
If you have a Sophos Web Appliance, Sophos Management Appliance, or Sophos UTM appliance
(version 9.2 or later) you can distribute an appliance-based policy to your users by way of Enterprise
Console.
Endpoint computers communicate with Enterprise Console in the same way as when the
Inappropriate Website Control policy is selected, but the web-filtering rules and web activity logs
are synchronized with the appliance that you specify. The policy is stored on endpoint computers
and applied, based on the latest Sophos data.
Users are blocked, warned or allowed, according to the web control policy. You can view user
activity data using the Reports and Search features on the Web Appliance or Management
Appliance, or Logging & Reporting > Web Protection option on the UTM appliance. Web control
events are all recorded on the appliance; however, sites scanned and assessed by Sophos
Endpoint Security and Control's live URL-filtering (Web protection) are recorded as web events
in Enterprise Console.
Note: Although HTTP and HTTPS sites are both filtered in all supported web browsers, in a Web
Appliance or Management Appliance user notifications are different, depending on whether the
URL is HTTP or HTTPS. With HTTP sites, users see notification pages for sites in categories set
to “Block” or “Warn.” For HTTPS, users only see “Block” notifications, and they are displayed as
a balloon tip in the Windows System Tray. HTTPS “Warn” actions are not displayed to users, nor
are they logged. Instead, users are allowed to continue to the requested page, and it is logged
as a “Proceed” event in the Web Appliance or Management Appliance.
UTM appliance uses a central cloud-based service called Sophos LiveConnect for protecting and
monitoring endpoint computers. LiveConnect allows you to always manage all of your endpoints,
whether they are on your local network, at remote sites, or with traveling users—policy updates
are distributed to users, and reporting data from endpoint computers is uploaded, even when
users are not connected from within the network.
When using Web Appliance or Management Appliance, endpoints can communicate with the
appliance either directly or through Sophos LiveConnect.
With Full Web Control selected, a full-featured policy takes effect. Full Web Control offers the
following benefits over basic web control, depending on the appliance you use:
■
Users are warned or blocked, based on over 50 categories of URLs.
■
Differentiated “Special Hours” policies can be applied.
■
Numerous additional policies can be used as per-user or per-group exceptions to the default
and Special Hours policies.

8 Setting up alerts and messages
8.1 About alerts and messages
There are several alerting methods used in Enterprise Console.
■
Alerts displayed in the console
If an item that requires attention is found on a computer, or an error has occurred, Sophos
Endpoint Security and Control sends an alert to Enterprise Console. The alert is displayed in
the computer list. For more information about dealing with such alerts, see Deal with alerts
about detected items (page 60).
These alerts are always displayed. You do not need to set them up.
■
Events displayed in the console
When an application control, firewall, patch assessment, web, data control, device control,
encryption or tamper protection event occurs on an endpoint computer, for example, an
application has been blocked by the firewall, that event is sent to Enterprise Console and can
be viewed in the respective event viewer.
■
Alerts and messages sent by the console to your chosen recipients
By default, when an item is found on a computer, a message is displayed on the computer
desktop and an entry is added to the Windows event log. When an application control, data
control, or device control event occurs, a message is displayed on the computer desktop.
Note: Optional user-defined desktop messages are not displayed on computers running
Windows 8.
You can also set up email alerts or SNMP messages for administrators.
Note: If you want to use authenticated SMTP for email alerts, see Sophos support
knowledgebase article 113780

Note: This feature will be unavailable if your license doesn't include Patch Assessment.
The Patch Assessment - Event Viewer contains information about security patches and results
of patch assessments.
The Patch updates field displays the download status of patch information. It displays one of the
following status messages:
■
Not downloaded indicates patch information is not downloaded or you do not have the license
to use the Patch feature.
■
Downloading indicates the first download, after install, is in progress.
■
OK indicates patch information is up-to-date.

10 Generating reports
10.1 About reports
Reports provide textual and graphical information on a variety of aspects of your network's security
status.
Reports are available via the Report Manager. Using the Report Manager, you can quickly
create a report based on an existing template, change configuration of an existing report, and
schedule a report to run at regular intervals, with the results being sent to your chosen recipients
as an email attachment. You can also print reports and export them in a number of formats.
Sophos provides a number of reports that you can use out of the box or configure to tailor your
needs. These reports are:
■
Alert and event history
■
Alert summary
■
Alerts and events by item name
■
Alerts and events by time
■
Alerts and events per location
■
Endpoint policy non-compliance
■
Events by user
■
Managed endpoint protection

11 Auditing
11.1 About auditing
Auditing enables you to monitor changes in Enterprise Console configuration and other user or
system actions. You can use this information for regulatory compliance and troubleshooting or,
in the case of malicious activity, during a forensic analysis.
By default, auditing is disabled. After you enable auditing, an audit entry is written to the auditing
database whenever certain configuration settings are changed or certain actions are performed.
Note: If you use role-based administration, you must have the Auditing right to enable or disable
auditing. For more information, see About roles and sub-estates (page 20).
The audit entry includes the following information:
■
Action performed
■
User who performed the action
■
User's computer
■
User's sub-estate
■
Date and time of the action
Both successful and failed attempts at actions are audited, so the audit entries can show who
performed actions on the system and who started actions that did not complete successfully.
Audited actions include:
Category

12 Recovering access to encrypted
computers
12.1 Recover access with Challenge/Response
Note: This feature will be unavailable if your license doesn't include Full Disk Encryption.
Challenge/Response 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. The help desk officer then generates a response code
that authorizes the user to perform a specific action on the computer.
For users to be able to recover access with Challenge/Response, the following prerequisites must
be fulfilled:
■
Challenge/Response needs to be enabled for endpoint computers in a full disk encryption
policy.
■
If you use role-based administration, you must have the right Remediation - encryption
recovery. For more information, see About roles and sub-estates (page 20).
■
If the user has forgotten their password, you must reset it in the Active Directory before
generating the response code.
■
If the user cannot log on because the Power-on Authentication is corrupt, make sure that the
key recovery file is exported and available in the user environment to initiate the
Challenge/Response procedure, see Export key recovery file (page 218).
1. On the endpoint computer the user initiates a Challenge/Response procedure, generates a
challenge code and contacts you.
For further information about initiating a Challenge/Response procedure in case of a forgotten
password, see the Sophos Disk Encryption user help. For further information about initiating
a Challenge/Response procedure in case the Power-on Authentication is corrupt, see the
Sophos Disk Encryption tools guide.
2. In the Computers list, right-click the respective computer and select Encryption Recovery.
The Encryption Recovery wizard is launched.
3. On the Select the recovery method page, select the required recovery method and click
Next.
■
■
If the user has forgotten their password, select Forgotten password (logon recovery).
If the user cannot log on because the Power-on Authentication is corrupt, select Power-on
Authentication corrupt (key recovery).
4. On the Enter the challenge page, enter the challenge code the user has provided and click
Next.
The response code is generated and displayed on the Tell end user the response page.
217
Sophos Enterprise Console
5. Tell the end user the response code.
If you tell the user the response code over the phone, you can use the Phonetic Alphabet
for easy spelling.
6. The user enters the response code on the endpoint computer.
Access to the endpoint computer is recovered.
12.1.1 Export key recovery file
If you use role-based administration, you must have the right Global encryption settings.
For more information, see About roles and sub-estates (page 20).
The key recovery file is used to initiate the Challenge/Response procedure on the endpoint
computer when the Power-on Authentication is corrupt and the user cannot log on to the computer.
The key recovery file must be exported. To initiate a Challenge/Response procedure when the
Power-on authentication is corrupt, see the Sophos Disk Encryption tools guide.
To export the key recovery file:
1. On the Tools menu, click Manage encryption and select Export key recovery file.
2. Select a location for the key recovery file *.TOK.
3. Make the key recovery file available to the help desk.
12.2 Recover access with Local Self Help
Note: This feature will be unavailable if your license doesn't include Full Disk Encryption.
With Local Self Help users who have forgotten their password can log on at their computer without
the assistance of a help desk. Users log on by answering predefined questions in the Power-on
Authentication on the endpoint computer.
For users to be able to recover access with Local Self Help, Local Self Help has to be enabled
in a full disk encrypion policy.
To recover access with Local Self Help:
1. On the endpoint computer, in the Power-on Authentication, the user enters their user name
and clicks the Recovery button.
2. In the following five dialogs, the user answers a defined number of questions randomly selected
from the questions stored on the endpoint computer. After answering the last one, the user
confirms the answers with OK.
3. 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.
4. After reading the password, the user clicks OK.
The user is logged on at the Power-on Authentication and to Windows and can use the password
for future logon.

14 Troubleshooting
14.1 Computers are not running on-access scanning
If there are computers not running on-access scanning:
1. Check which anti-virus and HIPS policy is used by those computers.
For details, see Check which policies a group uses (page 33).
2. Ensure that on-access scanning is enabled in that policy and that the computers comply with
the policy.
For details, see Turn on-access scanning on or off (page 90) and Make computers use the
group policy (page 40).
14.2 The firewall is disabled
If there are computers with the firewall disabled:
1. Check which firewall policy is used by those computers.
For details, see Check which policies a group uses (page 33).
2. Ensure that the firewall is enabled in that policy and that the computers comply with the policy.
For details, see Temporarily disable the firewall (page 120) and Make computers use the group
policy (page 40).
14.3 The firewall is not installed
Note: If you use role-based administration, you must have the Computer search, protection
and groups right to install the firewall. For more information, see About roles and sub-estates
(page 20).
Before you attempt to install the client firewall on endpoint computers, check that the computers
are running a Windows client operating system (Windows 2000 or later).
Note: You cannot install the firewall on computers running server operating systems or Windows
Vista Starter.
If there are computers on which you want to install the firewall:
1. Select the computers, right-click and select Protect Computers.

14.6 Cannot protect computers in the Unassigned group
The Unassigned group is only for holding computers that are not yet in groups created by you,
to which policies can be applied. You cannot protect computers until you place them in such a
group.
14.7 Sophos Endpoint Security and Control installation failed
If the Protect Computers Wizard fails to install Sophos Endpoint Security and Control on
computers, it could be because:
■
Enterprise Console does not know which operating system the computers are running. This
is probably because you did not enter your username in the format domain\user when finding
computers.
■
Automatic installation is not possible on that operating system. Perform a manual installation.
For instructions, see the Sophos Enterprise Console advanced startup guide.
■

http://www.sophos.com/en-us/support/knowledgebase/118859.aspx.
14.10 Anti-virus settings do not take effect on Linux or UNIX
Some anti-virus settings cannot be applied to Linux or UNIX computers. In this case, there is a
warning on that page of settings.
You can change anti-virus settings on Linux computers using the savconfig and savscan
commands as described in the Sophos Anti-Virus for Linux configuration guide. You can change
223
Sophos Enterprise Console
anti-virus settings on UNIX computers using the savscan command as described in the Sophos
Anti-Virus for UNIX configuration guide.
14.11 Linux or UNIX computer does not comply with policy
If you use a corporate configuration file in the CID, and the file contains a configuration value
which conflicts with the policy, the computer is shown as not complying with the policy.
Selecting the Comply with policy option brings the computer in compliance only temporarily,
until the CID-based configuration is reapplied.
To resolve the problem, review the corporate configuration file and, where possible, replace by
console-based configuration.
14.12 New scan appears unexpectedly on a Windows computer
If you look at the local copy of Sophos Endpoint Security and Control on Windows computers,
you may see that a new "Available scan" is listed, even though the user has not created one.
This new scan is actually a scheduled scan that you have set up from the console. You should
not delete it.
14.13 Connectivity and timeout problems
If the communications between Enterprise Console and a networked computer become slow or
the computer becomes unresponsive, there may be a connectivity problem.
Check the Sophos Network Communications Report that presents an overview of the current
state of communications between a computer and Enterprise Console. To view the report, go to
the computer where the problem occurred. On the taskbar, click the Start button, select All
Programs| Sophos| Sophos Endpoint Security and Control, and then click View Sophos
Network Communications Report.
The report shows possible problem areas and, if a problem is detected, remedial actions.
14.14 Adware and PUAs are not detected
If adware and other potentially unwanted applications (PUAs) are not detected, you should check
that:
■
Detection has been enabled. See Configure on-access scanning (page 88).
■
The applications are on a computer running Windows 2000 or later.
14.15 Partially detected item
Sophos Endpoint Security and Control may report that an item (for example, a Trojan or potentially
unwanted application) is "partially detected". This means that it has not found all the component
parts of that application.
224
Help
To find the other components, you need to carry out a full system scan of the computer(s) affected.
On computers running Windows 2000 or later, you can do this by selecting the computer(s),
right-clicking and selecting Full system scan. You can also set up a scheduled scan for adware
and other potentially unwanted applications. See Configure on-access scanning (page 88) and
Create a scheduled scan (page 95).
If the application has still not been fully detected, it may be because:
■
you have insufficient access rights
■
some drives or folders on the computer, containing the application's components, are excluded
from scanning.
If the latter is the case, check the list of items excluded from scanning (see Exclude items from
on-access scanning (page 93)). If there are some items on the list, remove them from the list and
scan your computer again.
Sophos Endpoint Security and Control may not be able to fully detect or remove adware and other
potentially unwanted applications with components installed on network drives.
For advice, contact Sophos technical support.
14.16 Frequent alerts about potentially unwanted applications
You may receive very large numbers of alerts about potentially unwanted applications, including
multiple reports of the same application.
This can occur because some types of potentially unwanted application "monitor" files, trying to
access them frequently. If you have on-access scanning enabled, Sophos Endpoint Security and
Control detects each file access and sends an alert.
You should do one of the following:
■
Disable on-access scanning for adware and PUA. You can use a scheduled scan instead.
■
Authorize the application (if you want to have it running on your computers). See Authorize
adware and PUAs (page 110).
■
Clean up the computer(s), removing applications that you have not authorized. See Clean up
computers now (page 62).
14.17 Cleanup failed
If Sophos Endpoint Security and Control fails in an attempt to clean up items ("Cleanup failed"),
the reason could be:
■
It has not found all the components of a multi-component item. Run a full system scan of the
computer(s) to find the other components. See Scan computers now (page 62).
■
Some drives or folders that contain item components are excluded from scanning. Check the
items excluded from scanning (see Exclude items from on-access scanning (page 93)). If
there are some items on the list, remove them from the list.
■
You have insufficient access rights.
■
It cannot clean up that type of item.
225
Sophos Enterprise Console
■
It has found a virus fragment, rather than an exact virus match.
■
The item is on a write-protected floppy disk or CD.
■
The item is on a write-protected NTFS volume (Windows 2000 or later).
14.18 Recover from virus side-effects
Cleanup can remove a virus from computers, but it cannot always reverse the side-effects.
Some viruses leave no side-effects. Others may make changes or corrupt data in ways that are
hard to detect. To deal with this, you should:
■
On the Help menu, click View Security Information. This connects you to the Sophos website,
where you can read the virus analysis.
■
Use backups or original copies of programs to replace infected programs. If you did not have
backup copies before the infection, create them now in case of future infections.
Sometimes you can recover data from disks damaged by a virus. Sophos can supply utilities for
repairing the damage caused by some viruses. Contact Sophos technical support for advice.
14.19 Recover from application side-effects
Cleanup can remove unwanted applications, but it cannot always reverse the side-effects.
Some applications modify the operating system, e.g. by changing your internet connection settings.
Sophos Endpoint Security and Control cannot always restore all settings. For example, if an
application changed the browser home page, Sophos Endpoint Security and Control cannot know
what the previous home page setting was.
Some applications install utilities, such as .dll or .ocx files, on your computer. If a utility is harmless
(that is, does not possess the qualities of a potentially unwanted application), e.g. a language
library, and is not integral to the application, Sophos Endpoint Security and Control may not detect
it as part of the application. In this case, cleanup won't remove the file from your computer.
Sometimes an application, such as adware, is part of a program that you intentionally installed,
and needs to be there for the program to run. If you remove the application, the program may
stop running on your computer.
You should:
■
On the Help menu, click View Security Information. This connects you to the Sophos website,
where you can read the application analysis.
■
Use backups to restore your system settings or programs you want to use. If you did not have
backup copies before, create them now in case of future incidents.
For more information or advice on recovering from an adware and PUA's side-effects, contact
Sophos technical support.

14.20 Data control does not detect files uploaded via
embedded browsers
Data control intercepts documents which are uploaded via standalone web browsers. It does not
intercept documents uploaded via browsers embedded in third-party applications (for example,
Lotus Notes). If you have a third-party application with an embedded browser and want to monitor
all uploaded documents, you must configure the application to launch an external browser.
14.21 Data control does not scan uploaded or attached files
If data control does not scan files uploaded or attached from a network location using a monitored
application (for example, an email client, a web browser, or an instant messaging (IM) client), it
may be because you excluded remote files from on-access scanning in the anti-virus and HIPS
policy. Data control uses the same set of exclusions as the Sophos Anti-Virus on-access scanner,
so if remote file scanning is disabled, it will not send any remote files for a data control check.
For information about configuring on-access scanning exclusions, see Exclude items from
on-access scanning (page 93).
Note: This restriction does not apply to storage device monitoring. Data control will intercept the
transfer of files onto monitored storage devices from a network location, for example, copying
files to a removable storage device or burning data onto optical media.
14.22 Uninstalled update manager is displayed in the console

new daylight savings times (DST) rules for the United States that expand DST as of March 2007.
Since DOC software obtains time/date and calendaring information from operating systems users
will not be affected by the new DST rules as long as they upgrade their operating systems
accordingly.
