9 Evaluation Analysis Activities
The evaluation analysis activities involved a structured evaluation of Avocent SwitchView
SC, including the following areas:
Development: The evaluators analyzed the Avocent SwitchView SC 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
Avocent SwitchView SC 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 Avocent SwitchView SC 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 Avocent SwitchView SC configuration management
system and associated documentation was performed. The evaluators found that the Avocent
SwitchView SC configuration items were clearly marked.
The evaluators examined the delivery documentation and determined that it described all of
the procedures required to maintain the integrity of Avocent SwitchView SC during
distribution to the consumer.
The evaluators reviewed the flaw remediation procedures used by developer for the Avocent
SwitchView SC. 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.
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 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 ETR1
.
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.
10.2 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. Repeat of Developer's Tests: The objective of this test goal is to repeat a subset of the
developer's tests;
b. Verification of Read Only Memory: The objective of this test goal is to determine that the
processor used in the TOE is able to protect its internal flash memory which is used to
store the TSF software;
c. Separation of Audio Output Data: The objective of this test goal is to verify that the audio
output data from each computer is separated; and
d. Initial Value on Start Up: The objective of this test goal is to determine if port A is
initially connected to a shared peripheral whether computer A powers up or not.
10.3 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. Misuse: The objective of this test goal is to concurrently push more than one port
selection button in an attempt to cause to the TOE to malfunction; and

b. Undocumented External Interfaces: The objective of this test goal is to enter shortcut key
sequences to verify that undocumented external interfaces are not present and/or
exploitable within the TOE.
The independent penetration testing did not uncover any exploitable vulnerabilities in the
intended operating environment.
10.4 Conduct of Testing
Avocent SwitchView SC 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.
10.5 Testing Results
The developer’s tests and the independent functional tests yielded the expected results,
providing assurance that Avocent SwitchView SC behaves as specified in its ST and
functional specification.
11 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.
