FOREWORD
The Canadian Common Criteria Evaluation and Certification Scheme (CCS) provide a third-
party evaluation service for determining the trustworthiness of Information Technology (IT)
security products. Evaluations are performed by a commercial Common Criteria Evaluation
Facility (CCEF) under the oversight of the CCS Certification Body, which is managed by the
Communications Security Establishment.
A CCEF is a commercial facility that has been approved by the CCS Certification Body to
perform Common Criteria evaluations; a significant requirement for such approval is
accreditation to the requirements of ISO/IEC 17025:2005, the General Requirements for the
Competence of Testing and Calibration Laboratories. Accreditation is performed under the
Program for the Accreditation of Laboratories - Canada (PALCAN), administered by the
Standards Council of Canada.
The CCEF that carried out this evaluation is CSC Security Testing/Certification Laboratories.
By awarding a Common Criteria certificate, the CCS Certification Body asserts that the
product complies with the security requirements specified in the associated security target. A
security target is a requirements specification document that defines the scope of the
evaluation activities. The consumer of certified IT products should review the security target,
in addition to this certification report, in order to gain an understanding of any assumptions
made during the evaluation, the IT product's intended environment, the evaluated security
functionality, and the testing and analysis conducted by the CCEF.
This certification report is associated with the certificate of product evaluation dated 25
November 2015, and the security target identified in Section 4 of this report.
The certification report, certificate of product evaluation and security target are posted on the
CCS Certified Products list (CPL) and the Common Criteria portal (the official website of the
Common Criteria Project).

6 Assumptions and Clarification of Scope
Consumers of nGenius® 3900 Series PFS should consider assumptions about usage and
environmental settings as requirements for the product’s installation and its operating
environment. This will ensure the proper and secure operation of the TOE.
6.1 Secure Usage Assumptions
The following Secure Usage Assumptions are listed in the ST:
• There are no general-purpose computing capabilities (e.g., compilers or user
applications) available on the TOE, other than those services necessary for the
operation, administration and support of the TOE; and
• TOE Administrators are trusted to follow and apply all administrator guidance in a
trusted manner.
6.2 Environmental Assumptions
The following Environmental Assumption is listed in the ST:
• Physical security, commensurate with the value of the TOE and the data it contains, is
provided by the environment.
7 Evaluated Configuration
The evaluated configuration for nGenius® 3900 Series PFS comprises:
One or more instances of the nGenius® 3900 Series PFS which is made up of either the PFS
3901 single slot chassis or PFS 3903 three slot chassis in single or multiple chassis.
For administering multiple chassis, a standalone dedicated PFS Management Server must be
used for user administration and device configuration. A single chassis can be managed by
the embedded management server or by the PFS Management Server. The PFS Management
Server is able to manage both the single or multiple chassis.
The publication entitled Common Criteria Supplemental Guidance for nGenius PFS
Management Server and PFS Switch Software Version 3.3.4 (Part Number 733-0504 Rev. A)
describes the procedures necessary to install and operate nGenius® 3900 Series PFS in its
evaluated configuration.

9 Evaluation Analysis Activities
The evaluation analysis activities involved a structured evaluation of nGenius® 3900 Series
PFS, including the following areas:
Development: The evaluators analyzed the nGenius® 3900 Series PFS functional
specification and determined that the functional specification describes the purpose and
method of use for each TSF interface and that the nGenius® 3900 Series PFS functional
specification is an accurate and complete instantiation of the SFRs.
Guidance Documents: The evaluators examined the nGenius® 3900 Series PFS 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 nGenius® 3900 Series PFS configuration
management system and associated documentation was performed. The evaluators found that
the nGenius® 3900 Series PFS configuration items were clearly marked.
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 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. NDPP required assurance activities: The objective of this test goal is to perform the
assurance activities mandated by the NDPP to which the TOE is claiming conformance.
10.2 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. NDPP required assurance activities. The evaluator performed the assurance activities
mandated by the protection profile to which the TOE is claiming conformance; and
b. Use of automated vulnerability scanning tools to discover potential network, platform and
application layer vulnerabilities.
The independent penetration testing did not uncover any exploitable vulnerabilities in the
intended operating environment.
10.3 Conduct of Testing
nGenius® 3900 Series PFS was subjected to a comprehensive suite of formally documented,
independent functional and penetration tests. The testing took place at the Information
Technology Security Evalution and Test Facility. The detailed testing activities, including
configurations, procedures, test cases, expected results and observed results are documented
in a separate Test Results document.
10.4 Testing Results
The independent tests yielded the expected results, providing assurance that nGenius® 3900
Series PFS behaves as specified in its ST and functional specification.
11 Results of the Evaluation
This evaluation has provided the basis for a NDPP conformance claim as claimed in Section
5. The overall verdict for the evaluation is PASS. These results are supported by evidence in
the ETR.

12 Evaluator Comments, Observations and Recommendations
The evaluator recommends that users follow the Common Criteria Supplemental Guidance
for nGenius PFS Management Server and PFS Switch Software Version 3.3.4 (Part Number
733-0504 Rev. A) closely, if they wish to deploy the evaluated configuration. Users should
contact NetScout Support if they have any questions or concerns about the advice provided
within the Common Criteria Supplemental Guidance. Departure from the evaluated
configuration should only be performed in consideration of the deployment scenario and
associated risk profile.
