Executive Summary
Forum Sentry v8.1.641 (hereafter referred to as Sentry 8.1.641), from Forum Systems, Inc.,
is the Target of Evaluation. Sentry 8.1.641 is conformant with the Protection Profile for
Network Devices Version 1.1, 08 June 2012, hereafter referred to as PP_ND_v1.1 .
Sentry 8.1.641 is a hardware TOE that provides application gateway functionality for a
variety of web-based (such as HTTP and XML) and non-web-based (such as SFTP and
LDAP) protocols. This functionality is implemented by an engine that examines application-
layer traffic elements to apply policy to traffic. Policy takes the form of application-firewall
rules, an antivirus engine, and pattern recognition rules. This allows the product to protect
against attacks and to enforce access control rules based on the information within XML
requests. The TOE functionality included within the scope of the evaluation is limited to the
secure management features described in the PP_ND_v1.1 .
CGI IT Security Evaluation & Test Facility is the CCEF that conducted the evaluation. This
evaluation was completed on 30 April 2014 and was carried out in accordance with the rules
of the Canadian Common Criteria Evaluation and Certification Scheme (CCS).
The scope of the evaluation is defined by the security target, which identifies assumptions
made during the evaluation, the intended environment for Sentry 8.1.641, and the security
requirements to which it is asserted that the product satisfies. Consumers are advised to
verify that their operating environment is consistent with that specified in the security target,
and to give due consideration to the comments, observations and recommendations in this
certification report.
Communications Security Establishment, as the CCS Certification Body, declares that the
Sentry 8.1.641 evaluation meets all the conditions of the Arrangement on the Recognition of

6 Assumptions and Clarification of Scope
Consumers of Sentry 8.1.641 should consider assumptions about usage and environmental
settings as requirements for the product’s installation and its operating environment. This
will ensure the proper and secure operation of the TOE.
6.1 Secure Usage Assumptions
The following Secure Usage Assumptions are listed in the ST:
• There are no general-purpose computing capabilities (e.g., compilers or user
applications) available on the TOE, other than those services necessary for the
operation, administration and support of the TOE; and
• TOE Administrators are trusted to follow and apply all administrator guidance in a
trusted manner.
6.2 Environmental Assumptions
The following Environmental Assumption is listed in the ST:
• Physical security, commensurate with the value of the TOE and the data it contains, is
provided by the environment.
6.3 Clarification of Scope
Sentry 8.1.641 application gateway functionality was not included within the scope of this
evaluation, only the functionality listed in the PP_ND_v1.1 is included.
When accessing the TOE via SSH, users of the TOE are required to configure the SSH client
to only use AES-CBC-128 and AES-CBC-256 for encryption. Use of any other encryption
algorithm for SSH is prohibited when the TOE is in its evaluated configuration. This was not
the intent of the SSH requirements in the NDPP, the TOE and not the client is supposed
enforce the use of AES-CBC-128 or AES-CBC-256 for encryption.

9 Evaluation Analysis Activities
The evaluation analysis activities involved a structured evaluation of Sentry 8.1.641,
including the following areas:
Development: The development documentation was not reviewed, as the requirements on
the content of the development documentation is implicitly assessed by virtue of the other
assurance activities listed in the PP being performed.
Guidance Documents: The evaluators examined the Sentry 8.1.641 preparative user
guidance and operational user guidance and determined that it sufficiently and
unambiguously describes how to securely transform the TOE into its evaluated configuration
and how to use and administer the product. The evaluators examined and tested the
preparative and operational guidance, and determined that they are complete and sufficiently
detailed to result in a secure configuration.
Life-cycle support: An analysis of the Sentry 8.1.641 configuration management system and
associated documentation was performed. The evaluators found that the Sentry 8.1.641

10 ITS Product Testing
Testing consists of the following three steps: assessing developer tests, performing
independent functional tests, and performing penetration tests.
10.1 Independent Functional Testing
During this evaluation, the evaluator developed independent functional tests by examining
design and guidance documentation.
All testing was planned and documented to a sufficient level of detail to allow repeatability
of the testing procedures and results. Resulting from this test coverage approach is the
following CGI IT Security Evaluation & Test Facility test goal:
a. PP_ND_v1.1 required assurance activities: The objective of this test goal is to perform
the assurance activities mandated by the PP_ND_v1.1
10.2 Independent Penetration Testing
Subsequent to the independent review of public domain vulnerability databases and all
evaluation deliverables, limited independent evaluator penetration testing was conducted.
The penetration tests focused on:
a. PP_ND_v1.1 required assurance activities: The objective of this test goal is to perform
the assurance activities mandated by the PP_ND_v1.1 ; and
b. Vulnerability scans: The objective of this test goal is the use of automated vulnerability
scanning tools to discover potential network, platform and application layer
vulnerabilities.
The independent penetration testing did not uncover any exploitable vulnerabilities in the
intended operating environment.
10.3 Conduct of Testing
Sentry 8.1.641 was subjected to a comprehensive suite of formally documented, independent
functional and penetration tests. The CCS Certification Body witnessed a portion of the
independent testing. The detailed testing activities, including configurations, procedures, test
cases, expected results and observed results are documented in a separate Test Results
document.
10.4 Testing Results
The independent functional tests yielded the expected results, providing assurance that Sentry
8.1.641 behaves as specified in its ST and functional specification.
11 Results of the Evaluation
This evaluation has provided the basis for a protection profile conformance claim as stated in
Section 5. The overall verdict for the evaluation is PASS. These results are supported by
evidence in the ETR.
