Executive Summary
Nutanix Virtual Computing Platform v3.5.1 (hereafter referred to as Nutanix VCP v3.5.1),
from Nutanix, Inc., is the Target of Evaluation. The results of this evaluation demonstrate
that Nutanix VCP v3.5.1 meets the requirements of Evaluation Assurance Level (EAL) 2
augmented for the evaluated security functionality.
Nutanix VCP v3.5.1 is a virtualization platform composed of a networked cluster of nodes
that can host VMs offering services to users (typically as virtual servers). These virtual
servers can be used for any application the users of the server require, such as web, email, or
others. Nutanix VCP v3.5.1also offers storage for those VMs to use when offering services.
The unification of storage and virtualization on a single platform eliminates the need for a
separate storage network.
Nodes are hardware boards housed within one or more chassis running the NOS (Nutanix
Operating System) software and provide all of the functionality for the cluster except data
storage. Data storage is provided by the disk hardware housed within the chassis. Each node
provides storage and virtualization services to users, with multiple nodes being used for
redundancy.
CGI IT Security Evaluation & Test Facility is the CCEF that conducted the evaluation. This
evaluation was completed on 26 August 2014 and was carried out in accordance with the
rules of the Canadian Common Criteria Evaluation and Certification Scheme (CCS).
The scope of the evaluation is defined by the security target, which identifies assumptions
made during the evaluation, the intended environment for Nutanix VCP v3.5.1, and the
security functional/assurance requirements. Consumers are advised to verify that their
operating environment is consistent with that specified in the security target, and to give due
consideration to the comments, observations and recommendations in this certification
report.
Communications Security Establishment, as the CCS Certification Body, declares that the
Nutanix VCP v3.5.1 evaluation meets all the conditions of the Arrangement on the
Recognition of Common Criteria Certificates and that the product will be listed on the CCS
Certified Products list (CPL) and the Common Criteria portal (the official website of the

9 Evaluation Analysis Activities
The evaluation analysis activities involved a structured evaluation of Nutanix VCP v3.5.1,
including the following areas:
Development: The evaluators analyzed the Nutanix VCP v3.5.1 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
Nutanix VCP v3.5.1 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 Nutanix VCP v3.5.1 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 Nutanix VCP v3.5.1 configuration management
system and associated documentation was performed. The evaluators found that the Nutanix
VCP v3.5.1 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 Nutanix VCP v3.5.1 during distribution
to the consumer.
The evaluators reviewed the flaw remediation procedures used by developer for the Nutanix
VCP v3.5.1. 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. Privilege escalation: The objective of this test goal is to confirm that a user cannot
escalate their privileges from one type of administrator to another;
c. Audit generation: The objective of this test goal is to test the audit generation
functionality using a variety of parameters; and
d. REST API: The objective of this test goal is to test the ability of an administrator to
manage the TOE using the Nutanix REST API.
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.
b. HeartBleed: The objective of this test goal is to determine if the TOE is susceptible to
HeartBleed;
c. NFS Whitelist: The objective of this test goal is to attempt to gain access to restricted
storage using Whitelisted IPs; and
1
The ETR is a CCS document that contains information proprietary to the developer and/or the evaluator, and
is not releasable for public review.

d. IPMI port vulnerability: The objective of this test goal is to connect to the IPMI port and
attempt to gain access to protected user credentials.
The independent penetration testing did not uncover any exploitable vulnerabilities in the
intended operating environment.
10.4 Conduct of Testing
Nutanix VCP v3.5.1 was subjected to a comprehensive suite of formally documented,
independent functional and penetration tests. The testing took place at the CGI IT Security
Evaluation & Test Facility. The CCS Certification Body witnessed a portion of the
independent testing. 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 Nutanix VCP v3.5.1 behaves as specified in its ST and functional
specification.
11 Results of the Evaluation
This evaluation has provided the basis for an EAL 2+ level of assurance. The overall verdict
for the evaluation is PASS. These results are supported by evidence in the ETR.
12 Evaluator Comments, Observations and Recommendations
TOE users should be aware that at least four (4) independent nodes are required to comprise
the evaluated configuration. These nodes are not required to be situated within a single
chassis, but users should consult appropriate Nutanix documentation to ensure their node
selection is appropriate for their needs.
