10 Evaluation Analysis Activities
The evaluation analysis activities involved a structured evaluation of MWG, including the
following areas:
Development: The evaluators analyzed the MWG 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 MWG 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 MWG 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 MWG configuration management system and
associated documentation was performed. The evaluators found that the MWG 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.
The evaluators examined the delivery documentation and determined that it described all of
the procedures required to maintain the integrity of MWG during distribution to the
consumer.
The evaluators reviewed the flaw remediation procedures used by developer for the MWG.
During a site visit, the evaluators also examined the evidence generated by adherence to the
procedures. The evaluators concluded that the procedures are adequate to track and correct
security flaws, and distribute the flaw information and corrections to consumers of the
product.

Vulnerability assessment: The evaluators conducted an independent vulnerability analysis
of MWG. Additionally, the evaluators conducted a search of public domain vulnerability
databases to identify MWG potential vulnerabilities. The evaluators identified potential
vulnerabilities for testing applicable to MWG 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 ETR2
.
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;
b. Creation of new permission sets: The objective of this test goal is to confirm that new
permission sets can be created and enforced;
c. TOE Access: The objective of this test goal is to test the various methods of access the
TOE and that user authentication is enforced on each. It also covers testing for
concurrent users;

d. Unintended reboot: The objective of this test goal is to confirm the TOE's response to an
unintended reboot/improper shutdown; and
e. Audit overflow: The objective of this test goal is to confirm how the TOE reacts when
the maximum size of the audit file is reached.
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
MWG 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.
11.5 Testing Results
The developer’s tests and the independent functional tests yielded the expected results,
giving assurance that MWG behaves as specified in its ST and functional specification.
12 Results of the Evaluation
This evaluation has provided the basis for an EAL 2+ level of assurance. The overall verdict
for the evaluation is PASS. These results are supported by evidence in the ETR.
13 Evaluator Comments, Observations and Recommendations
The evaluator recommends that the user read the ST and all supplemental documentation to
make sure that all necessary steps are taken to configure the device for operation in its
intended environment; critically, the TOE must be installed in "FIPS mode" prior to any
other configuration options can be considered. The evaluator strongly recommends that
potential administrators engage in professional training to fully understand the multitude of
