FOREWORD
The Canadian Common Criteria Evaluation and Certification Scheme (CCS) provide a third-
party evaluation service for determining the trustworthiness of Information Technology (IT)
security products. Evaluations are performed by a commercial Common Criteria Evaluation
Facility (CCEF) under the oversight of the CCS Certification Body, which is managed by the
Communications Security Establishment.
A CCEF is a commercial facility that has been approved by the CCS Certification Body to
perform Common Criteria evaluations; a significant requirement for such approval is
accreditation to the requirements of ISO/IEC 17025:2005, the General Requirements for the
Competence of Testing and Calibration Laboratories. Accreditation is performed under the
Program for the Accreditation of Laboratories - Canada (PALCAN), administered by the
Standards Council of Canada.
The CCEF that carried out this evaluation is CGI IT Security Evaluation & Test Facility.
By awarding a Common Criteria certificate, the CCS Certification Body asserts that the
product complies with the security requirements specified in the associated security target. A
security target is a requirements specification document that defines the scope of the
evaluation activities. The consumer of certified IT products should review the security target,
in addition to this certification report, in order to gain an understanding of any assumptions
made during the evaluation, the IT product's intended environment, the evaluated security
functionality, and the testing and analysis conducted by the CCEF.
This certification report is associated with the certificate of product evaluation dated 8
September 2014, and the security target identified in Section 4 of this report.
The certification report, certificate of product evaluation and security target are posted on the
CCS Certified Products list (CPL) and the Common Criteria portal (the official website of the
Common Criteria Project).

Internal and External Network (typically an office network and the Internet), and to provide
WAN optimization for traffic passing between networks.
CGI IT Security Evaluation & Test Facility is the CCEF that conducted the evaluation. This
evaluation was completed on 30 July 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 Blue Coat ProxySG, and the
security functional/assurance requirements. 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
Blue Coat ProxySG evaluation meets all the conditions of the Arrangement on the

9 Evaluation Analysis Activities
The evaluation analysis activities involved a structured evaluation of Blue Coat ProxySG,
including the following areas:
Development: The evaluators analyzed the Blue Coat ProxySG functional specification and
determined that the functional specification describes the purpose and method of use for each
TSF interface and that the Blue Coat ProxySG functional specification is an accurate and
complete instantiation of the SFRs.
Guidance Documents: The evaluators examined the Blue Coat ProxySG 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 Blue Coat ProxySG configuration management
system and associated documentation was performed. The evaluators found that the Blue
Coat ProxySG configuration items were clearly marked.
All these evaluation activities resulted in PASS verdicts.

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 list of test goals:
a. NDPP required assurance activities: The objective of this test goal is to perform the
assurance activities mandated by the NDPP to which the TOE is claiming conformance.
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. NDPP required assurance activities. The evaluator performed the assurance activities
mandated by the protection profile to which the TOE is claiming conformance; and
b. 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
Blue Coat ProxySG was subjected to a comprehensive suite of formally documented,
independent functional and penetration tests. The testing took place at the Information
Technology Security Evaluation and Test Facility. 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 tests yielded the expected results, providing assurance that Blue Coat
ProxySG behaves as specified in its ST and functional specification.
11 Results of the Evaluation
This evaluation has provided the basis for a NDPP conformance claim as claimed in Section
5. The overall verdict for the evaluation is PASS. These results are supported by evidence in
the ETR.

12 Evaluator Comments, Observations and Recommendations
During the course of the evaluation, the evaluator determined some security functions of the
TOE are enforced by the installed policy which are written in CPL (Content Policy
Language). Each web request is also evaluated and actioned based on the installed policy.
Since misconfiguration of the policy may have detrimental effect; the evaluator recommends
an administrator who is competent with Visual Policy Manager (VPM) or the CPL syntax in
order to define or compose the security policy. Such knowledge is also critical for
troubleshooting and to maintain normal operation of the TOE.
