11 Evaluation Analysis Activities
The evaluation analysis activities involved a structured evaluation of MICROTECH
M7245/M7246/M7248, including the following areas:
Configuration management: An analysis of the MICROTECH M7245/M7246/M7248
configuration management system and associated documentation was performed. The
evaluators found that the MICROTECH M7245/M7246/M7248 configuration items were
clearly marked, and could be modified and controlled, and that the configuration
management system supported generation of the TOE. The developer’s configuration
management system was observed during a site visit, and it was found to be mature and well-
developed.
Secure delivery and operation: The evaluators examined the delivery documentation and
determined that it described all of the procedures required to maintain the integrity of
MICROTECH M7245/M7246/M7248 during distribution to the consumer. The evaluators
examined and tested the installation, generation and start-up procedures, and determined that
they were complete and sufficiently detailed to result in a secure configuration.
Design documentation: The evaluator analyzed the MICROTECH M7245/M7246/M7248
functional specification, high-level design, low-level design, security policy model, and a
subset of the implementation representation; they determined that the documents are
internally consistent, and completely and accurately instantiated all interfaces and security
functions. The evaluator also independently verified that the correspondence mappings
between the design documents are correct.
Guidance Documents: The evaluators examined the MICROTECH M7245/M7246/M7248
administrator and user guidance documentation and determined that it sufficiently and
unambiguously describes how to securely use and administer the product, and that it is
consistent with the other documents supplied for evaluation.
Life-cycle support: The evaluators examined the development security procedures during a
site visit and determined that they detailed sufficient security measures for the development
environment to protect the confidentiality and integrity of the MICROTECH
M7245/M7246/M7248 design and implementation. The evaluators determined that the
developer has used a documented model of the TOE life-cycle and well-defined development
tools that yield consistent and predictable results.
Vulnerability assessment: The evaluators examined the developer’s vulnerability analysis
for MICROTECH M7245/M7246/M7248 and found that it sufficiently described each of the
potential vulnerabilities along with a sound rationale as to why it was not exploitable in the
intended environment. Additionally, the evaluators conducted an independent review of
CCS Certification Report MICROTECH
MICROTECH M7245/M7246/M7248

Version 1.0 26 May 2010
- Page 6 of 8 -
public domain vulnerability databases, and all evaluation deliverables to provide assurance
that the developer has considered all potential vulnerabilities.
All these evaluation activities resulted in PASS verdicts.
12 ITS Product Testing
Testing at EAL 4 consists of the following three steps: assessing developer tests, performing
independent functional tests, and performing penetration tests.
12.1 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 and depth analysis and found them to
be complete and accurate. The correspondence between the tests identified in the developer’s
test documentation and the functional specification, TOE design and security architecture
description was complete.
12.2 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 was the
following list of DOMUS ITSL test goals:
• Repeat of Developer's Tests: The objective of this test goal is to repeat a subset of the
developer's tests;
• Self-protection: The objective of this test goal is to determine the TOE's ability to protect
itself from improper command sets; and
• Isolation: The objective of this test goal is to determine that the two channels are isolated
from one another and meet isolation requirements.

12.3 Independent Penetration Testing
Subsequent to the independent review of public domain vulnerability databases and a
focused review of all evaluation deliverables, limited independent evaluator penetration
testing was conducted. The penetration tests focused on:
• Switching: The objectives of this test goal are to determine the effects of simultaneous
manual/remote switch configuration and of switch reconfiguration while data is being
transmitted; and
• TOE Reset: The objective of this test goal is to determine that switch configuration
settings are maintained on a power failure/power reset.
The independent penetration testing did not uncover any exploitable vulnerabilities in the
anticipated operating environment.
12.4 Conduct of Testing
The MICROTECH M7245/M7246/M7248 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 DOMUS
ITSL. The detailed testing activities, including configurations, procedures, test cases,
expected results and observed results are documented in a separate Test Results document.
12.5 Testing Results
The developer’s tests and the independent functional tests yielded the expected results,
giving assurance that MICROTECH M7245/M7246/M7248 behaves as specified in its ST
and functional specification.
13 Results of the Evaluation
This evaluation has provided the basis for an EAL 4 level of assurance. The overall verdict
for the evaluation is PASS. These results are supported by evidence in the ETR.
14 Evaluator Comments, Observations and Recommendations
Consumers should review the security aspects of the intended environment, as detailed in
section 3 of the ST.
