5 EVALUATION ANALYSIS ACTIVITIES
The evaluation analysis activities involved a structured evaluation of the TOE. Documentation and process
dealing with Development, Guidance Documents, and Life-Cycle Support were evaluated.
5.1 DEVELOPMENT
The evaluators analyzed the documentation provided by the vendor; they determined that the design
completely and accurately describes the TOE security functionality (TSF) interfaces and how the TSF implements
the security functional requirements (SFRs). The evaluators determined that the initialization process is secure,
that the security functions are protected against tamper and bypass, and that security domains are maintained.
5.2 GUIDANCE DOCUMENTS
The evaluators examined the TOE 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.
Section 4.1 provides details on the guidance documents.
5.3 LIFE-CYCLE SUPPORT
An analysis of the TOE configuration management system and associated documentation was performed. The
evaluators found that the TOE 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 the TOE during distribution to the consumer.

6 TESTING ACTIVITIES
Testing consists of the following three steps: assessing developer tests, performing independent functional tests,
and performing penetration tests.
6.1 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 ETR. The correspondence between the tests identified in
the developer’s test documentation and the functional specification was complete.
6.2 CONDUCT OF TESTING
The TOE was subjected to a comprehensive suite of formally documented, independent functional and
penetration tests. The detailed testing activities, including configurations, procedures, test cases, expected
results and observed results are documented in a separate Test Results document.
6.3 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. The following testing activities were performed:
a. Repeat of Developer's Tests: The evaluator repeated a subset of the developers tests;
b. Default Password Change: The objective of this test goal is to confirm that administrators are required
to change default passwords prior to login;
c. Administrator Account Permissions: The objective of this test goal is to confirm that access to the root
account is disabled;
d. Node Locking: The objective of this test goal is to confirm that only the Lock Admin can lock/unlock
remote access sessions to the ECS Nodes;
e. Logging: The objective to this test goal is to confirm that administrative actions are logged;
f. Compliance and Retention Policy: The objective of this test goal is to confirm that the TOE enforces rules
for compliance and retention policies; and
g. Network Encryption: The objective of this test goal is to confirm that all communication via the
management and data paths are encrypted.
6.3.1 FUNCTIONAL TEST RESULTS
The developer’s tests and the independent functional tests yielded the expected results, providing assurance
that the TOE behaves as specified in its ST and functional specification.
UNCLASSIFIED
V1.0 9
6.4 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 such as Heartbleed, Shellshock, FREAK, POODLE, and GHOST; and
b. Information Leakage: The evaluator monitored the TOE during start-up and shutdown to determine if
any sensitive information was made available during these times.
c. Misuse: The evaluator physically disconnected the TOE from the management console during use to
determine if any sensitive information was made available during this time and that user had to log back
in.
d. Direct Attack: The evaluator unplugged the power to the TOE during use and plugged it back in to verify
that a secure state was maintained after the power outage.
6.4.1 PENETRATION TEST RESULTS
The independent penetration testing did not uncover any exploitable vulnerabilities in the intended operating
environment.
