is secure and 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 NI GigaStor 14.1 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 NI GigaStor 14.1 configuration management system
and associated documentation was performed. The evaluators found that the NI GigaStor
14.1 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.
The evaluators examined the delivery documentation and determined that it described all of
the procedures required to maintain the integrity of NI GigaStor 14.1 during distribution to
the consumer.
The evaluators reviewed the flaw remediation procedures used by Network Instruments for
NI GigaStor 14.1. 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.

The evaluators analyzed the developer’s test coverage and found it to be complete and
accurate. The correspondence between the tests identified in the developer’s test
documentation and the functional specification and TOE design 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 was the
following list of EWA-Canada test goals:
a. Initialization: The objective of this test goal is to confirm that the TOE can be installed
and configured into the evaluated configuration, as identified in the TOE Description of
the Security Target, by following all instructions in the developer’s Installation and
Administrative guidance;
b. Repeat of Developer's Tests: The objective of this test goal is to repeat the developer's
tests on the evaluator’s TOE installation. In order to avoid test case dependency issues,
all of the developer's tests as documented in the developer's Test Procedure document
were repeated in the order presented;
c. Traffic Capture and Analysis: The objective of this test goal is to exercise the TOE’s
claimed traffic capture and analysis functionality;
d. DAC Policy: The objective of this test goal is to exercise the TOE’s claimed DAC
Policy to control user access to TOE resources;
e. Identification and Authentication: The objective of this test goal is to exercise the TOE’s
claimed identification and authentication functionality; and
f. Alert Logging: The objective of this test goal is to exercise the TOE’s claimed alert
logging functionality.
11.3 Conduct of Testing
NI GigaStor 14.1 was subjected to a comprehensive suite of formally documented,
independent functional and penetration tests. The testing took place at the ITSET Facility at
EWA-Canada. The CCS Certification Body witnessed the independent testing. The detailed
