About the Common Criteria
The Common Criteria for Information Technology Security Evaluation (or “Common Criteria”) provides
a methodology for evaluating security features of IT products. Product vendors pursue Common
Criteria evaluation to meet assurance needs of customers and to seek third-party validation of security
function claims. The Target of Evaluation (TOE) encompasses the evaluated security functionality of a
product.
Introduction
Assumptions
6 Operational User Guidance and Preparative Procedures Supplement for Common Criteria
The McAfee VirusScan Enterprise 8.8 and ePolicy Orchestrator 4.5 (hereafter called “Target of
Evaluation” or the “TOE”) has achieved Common Criteria Evaluation Assurance Level 2 and augmented
by ALC_FLR.2 – Flaw Reporting Procedures.
Please visit: http://www.commoncriteriaportal.org for more information on the Common Criteria.
Assumptions
The TOE and the TOE operating environment should be managed to satisfy the assumptions presented
in the following sections.
Authorized Administrators
Authorized administrators are non-hostile, are authenticated to the internal network, and follow all
administrator guidance. Human users (considered to be anyone who interacts with the TOE) who are
not authorized administrators cannot access the administration features.
Physical Access
The TOE must be located in a physically secure environment, and only an authorized administrator has
access to this environment. The evaluated configuration of the TOE can be compromised if an intruder
gains physical access to the product. Therefore only authorized administrators shall be allowed
physical access to the workstation(s) for power/reset controls.

all user accounts defined in McAfee ePO must specify Windows authenticaltion (rather than McAfee
ePO authentication).
Installation Guidelines and Preparative Procedures
Verify Software
Operational User Guidance and Preparative Procedures Supplement for Common Criteria 9
The evaluated configuration includes one or more instances of McAfee Agent and VirusScan Enterprise
and an instance of McAfee ePO. The following configuration should apply to the evaluated
configuration:
1 All user accounts defined in McAfee ePO must specify Windows authentication.
2 McAfee Agent should only be installed by using the McAfee ePO interface.
3 Remote viewing of TOE log files on the clients is disabled.
4 Only authorized processes may initiate network connections to remote port 25 (SMTP). The
Central Administrator configures the list of authorized processes.
5 The U.S. Government Protection Profile Anti-Virus Applications for Workstations in Basic
Robustness Environments requires the TOE to restrict specific management functionality to the
Central Administrator role. At least one ePO user must be defined as a Central Administrator. For
this TOE, the Central Administrator role is defined as an authorized administrator with Global
Administrator status.
6 Because the
U.S. Government Protection Profile Anti-Virus Applications for Workstations in Basic
Robustness Environments requires the TOE to restrict specific management functionality to the
Central Administrator role, the following permissions may never be assigned:
a View audit log.
b View and purge audit log.
c View VSE settings.
d View and change VirusScan Enterprise settings.
Functionality Not Included in the Evaluation
The following functionality is not included in the evaluation:
The ability to protect against buffer overflows
The ability to identify spyware
The Scriptscan feature that scans JavaScript and VBScript scripts
The ability to update the TOE (scan engine). Note that the ability to update the virus
signatures (DAT file) is included in the evaluation.
The optional Alert Manager product
Verify Software
The administrator should follow one of the following points to ensure the proper version of software is
installed:
The administrator can view McAfee ePO versioning information on the title bar/tab header
when logged into ePolicy Orchestrator:
Installation Guidelines and Preparative Procedures
Install Database Capacity Monitor Extension
10 Operational User Guidance and Preparative Procedures Supplement for Common Criteria
The administrator can view VirusScan Enterprise versioning information via Menu / Software /
Extensions / VirusScan Enterprise when logged into ePolicy Orchestrator
Updating System Software
If the TOE is not running the evaluated version of software, the administrator should contact McAfee
to obtain the appropriate license/grant for the evaluated software version.
Install Database Capacity Monitor Extension
The purpose of the feature is to enable the use of automatic responses to alert the administrator of
the exhaustion of storage space being used by the SQL database. To facilitate events, a new project
has been created that allows the user to configure alert settings. This project is being released by way
of an extension and can be installed by the end user.
To install the Database Capacity Monitor Extension, follow the instructions below:
1 Download the Database Capacity Monitor Extension (DBCapMon.zip) from McAfee Service Portal.
2 As a Global Admin, select Software / Extensions from the main menu.

Creating and generating responses for Database is a three-part sequence. These steps require
adjusting or reviewing database limits, setting up a server task and finally creating an Automatic
Response.
Step 1: Adjust or Review Database space requirements
The user can create a query for systems with less than, for example, 10GB free of system drive space.
The user can create a server task to mail the results of this query to a designated recipient. From the
server configuration, select the “Database watcher limits” category. Clicking edit will that use to
specify the maximum expected database and the percentage at which a server event will be triggered.
Step 2: Create a Server Task to generate the Event
To use the limits specified a user must create a server task to run the “Check Database Size” action
and set a schedule at which the limits will be queried.
1 New Server Task:

12 Operational User Guidance and Preparative Procedures Supplement for Common Criteria
a Provide name and Enable the task.
b Select the “Check Database Size” action.
c Provide schedule settings.
d Review and save the server task.
This server task creates entries in the EPOServerEvents table using the event id of ‘16081’ and
contains information pertaining to the audit log entry and server information. The presence of the
event id in this table represents the limits have been met based on the criteria set in the configuration
screen. This process does not generate the alerts and communication; this will be via an automatic
response.
Step 3: Setting up the automatic response
1 Select the ePO Notification group, and specify “server” from the event type.

2 Add the Event ID as a filter and specify ‘16081’ as the value:
On the Aggregation tab of the Automatic Response builder screen, it should be noted that
throttling should be used in order to not overload an overload system.
From the Actions screen the user can specify the appropriate response; in this case a server issue
is being created and assigned to the global administrator.

3 Guidance for Administrators
The Common Criteria evaluated configuration is designed to be as flexible as possible in a deployment
scenario. As such, the ongoing guidance for administrators is largely covered in the McAfee VirusScan
Enterprise 8.8 software Product Guide. Administrators should read and configure the software
according to the guidelines in available documentation and according to their site-specific security
policies. Following those guidelines and those mentioned below will ensure that the TOE is
administered in a manner that complies with the Common Criteria evaluation.
Contents
Software Version Inspection
Required Password Length
Software Version Inspection
The administrator should periodically verify that the evaluated version of software is running.
Required Password Length
When adding other administrator accounts to the TOE, the administrator should choose strong
passwords by adhering to the following rules:
Use long passwords (8 characters or longer).
Do not use something found in a dictionary (in any language or jargon).
Do not use a name (including that of a spouse, parent, child, pet, fantasy character, famous
person, and location) or any variation of the account name or administrator identity.
Do not use accessible information (such as phone numbers, license plates, or social security
numbers).
Do not use a birthday or a simple number pattern.
Use a mixture of upper and lower case letters, as well as digits or punctuation. When choosing
a new password, make sure it is unrelated to any previous password.
Note that the administrator should also follow these rules when maintaining his/her own password.
