9 Evaluation Analysis Activities
The evaluation analysis activities involved a structured evaluation of Tanium Platform 6.2,
including the following areas:
Development: The evaluators analyzed the Tanium Platform 6.2 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 Tanium
Platform 6.2 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 Tanium Platform 6.2 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 Tanium Platform 6.2 configuration management
system and associated documentation was performed. The evaluators found that the Tanium
Platform 6.2 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 Tanium Platform 6.2 during distribution
to the consumer.
The evaluators reviewed the flaw remediation procedures used by developer for the Tanium
Platform 6.2. 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. Security Audit: The objective of this test goal is to confirm that audit records can be
viewed and that they cannot be deleted unless authorized;
c. Identification and Authentication: The objective of this test goal is to confirm that
administrators must be identified and authenticated before actions can be performed on
the Tanium console;
d. User Data Protection: The objective of this test goal is to confirm that traffic between the
Tanium server, client, and console is protected; and
e. Security Management: The objective of this test goal is to confirm that a user without the
action approver privilege cannot approve actions and a read only user’s privileges are
limited.
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. Use of automated vulnerability scanning tools to discover potential network, platform and
application layer vulnerabilities.

Tanium Platform 6.2 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.
10.5 Testing Results
The developer’s tests and the independent functional tests yielded the expected results,
providing assurance that Tanium Platform 6.2 behaves as specified in its ST and functional
specification.
11 Results of the Evaluation
This evaluation has provided the basis for a EAL 2+ level of assurance. The overall verdict
for the evaluation is PASS. These results are supported by evidence in the ETR.
