9 Evaluation Analysis Activities
The evaluation analysis activities involved a structured evaluation of Tintri VMstore
v3.1.2.1, including the following areas:
Development: The evaluators analyzed the Tintri VMstore v3.1.2.1 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
Tintri VMstore v3.1.2.1 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 Tintri VMstore v3.1.2.1 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 Tintri VMstore v3.1.2.1 configuration management
system and associated documentation was performed. The evaluators found that the Tintri
VMstore v3.1.2.1 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 Tintri VMstore v3.1.2.1 during
distribution to the consumer.
The evaluators reviewed the flaw remediation procedures used by developer for the Tintri
VMstore v3.1.2.1. 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.
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. Identification and authentication via REST API call: The objective of this test goal is to
confirm that users and authenticate via the REST API call;
c. User roles: The objective of this test goal is to confirm that users can be
created/modified/deleted and that user roles can be assigned;
d. Configuring Active directory Services: The objective of this test goal is to confirm that
the TOE can be configured to use active directory;
e. Failure with preservation of secure state: The objective of this test goal is to confirm that
the TOE and preserve a secure state in the event of a system failure;
f. Configuring NFS: The objective of this test goal is to confirm that the TOE can be
configured to use NFS; and
