10 Evaluation Analysis Activities
The evaluation analysis activities involved a structured evaluation of MEG v7.0.1, including
the following areas:
Development: The evaluators analyzed the MEG v7.0.1 functional specification and design
documentation; they determined that the design completely and accurately describes the TOE
security functionality (TSF) interfaces, the TSF subsystems and how the TSF implements the
security functional requirements (SFRs). The evaluators analyzed the MEG v7.0.1 security
architectural description and determined that the initialization process is secure, that the
security functions are protected against tamper and bypass, and that security domains are
maintained. The evaluators also independently verified that the correspondence mappings
between the design documents are correct.
Guidance Documents: The evaluators examined the MEG v7.0.1 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 MEG v7.0.1 configuration management system and
associated documentation was performed. The evaluators found that the MEG v7.0.1
configuration items were clearly marked. The developer’s configuration management system
was observed during a site visit, and it was found to be mature and well-developed.

to theprocedures. Theevaluatorsconcluded that theproceduresareadequateto track and
correct security flaws, and distributetheflaw information and correctionsto consumersof the
product.
Vulnerability assessment: The evaluators conducted an independent vulnerability analysis
of MEG v7.0.1. Additionally, the evaluators conducted a search of public domain
vulnerability databases to identify MEG v7.0.1 potential vulnerabilities. The evaluators
identified potential vulnerabilities for testing applicable to MEG v7.0.1 in its operational
environment.
All these evaluation activities resulted in PASS verdicts.
11 ITS Product Testing
Testing at EAL 2 consists of the following three steps: assessing developer tests, performing
independent functional tests, and performing penetration tests.
11.1 Assessment of Developer Tests
The evaluators verified that the developer has met their testing responsibilities by examining
their test evidence, and reviewing their test results, as documented in the ETR3
The evaluators analyzed the developer’s test coverage analysis and found it to be complete
and accurate. The correspondence between the tests identified in the developer’s test
documentation and the functional specification was complete.
.
11.2 Independent Functional Testing
During this evaluation, the evaluator developed independent functional tests by examining
design and guidance documentation, examining the developer's test documentation, executing
a sample of the developer's test cases, and creating test cases that augmented the developer
tests.

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 EWA-Canada test goals:
a. Repeat of Developer's Tests: The objective of this test goal is to repeat a subset of the
developer's tests; and
b. Identification and Authentication: The objective of this test goal is to confirm login
failures and concurrent logins.
11.3 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. Use of automated vulnerability scanning tools to discover potential network, platform and
application layer vulnerabilities; and
b. Leakage Verification. In this test case the TOE is monitored for information leakage
during start-up and shutdown.
The independent penetration testing did not uncover any exploitable vulnerabilities in the
intended operating environment.
11.4 Conduct of Testing
MEG v7.0.1 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 (ITSET) Facility at EWA-Canada. 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.
