8 Architectural Information
FTOS 7.8 is a custom implementation of the Unix operating system based upon NetBSD.
FTOS 7.8 consists of two subsystems which are the NetBSD/HAL kernel which implements
a stable OS providing memory allocation, scheduling and hardware drivers, and the Process
Space which provides the routing, switching and management functions specific to the TOE.
The NetBSD/HAL subsystem provides both standard operating system functionality (based
on a custom implementation of NetBSD v1.6) as well as a hardware abstraction layer (HAL)
which provides specific device drivers for the Force10 switches and switch/routers.
The Process Space subsystem implements processes which provide specific Force10
switching and routing functions on top of the NetBSD OS. The following processes are
executed as part of the Process Space subsystem:
• Layer 2 switching protocols;
• Layer 3 routing protocols;
• System services and management functions ; and
• Security services and protocols.

11 Evaluation Analysis Activities
The evaluation analysis activities involved a structured evaluation of FTOS 7.8, including the
following areas:
Development: The evaluators analyzed the FTOS 7.8 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 FTOS 7.8 security
architectural description and determined that the initialization process was 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 were correct.

Guidance Documents: The evaluators examined the FTOS 7.8 preparative user guidance
and operational user guidance and determined that it sufficiently and unambiguously
described 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 were complete and sufficiently detailed to
result in a secure configuration.
Life-cycle support: An analysis of the FTOS 7.8 configuration management system and
associated documentation was performed. The evaluators found that the FTOS 7.8
configuration items were clearly marked. The developer’s configuration management system
was observed during a site visit, and it was found to be mature and well developed.
The evaluators examined the delivery documentation and determined that it described all of
the procedures required to maintain the integrity of FTOS 7.8 during distribution to the
consumer.
Vulnerability assessment: The evaluators conducted an independent vulnerability analysis
of FTOS 7.8. Additionally, the evaluators conducted a search of public domain vulnerability
databases to identify FTOS 7.8 potential vulnerabilities. The evaluators identified potential
vulnerabilities for testing applicable to the FTOS 7.8 in its operational environment.
All these evaluation activities resulted in PASS verdicts.
12 ITS Product Testing
Testing at EAL 2 consists of the following three steps: assessing developer tests, performing
independent functional tests, and performing penetration tests.
12.1 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 ETR2
.
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.
12.2 Independent Functional Testing
During this evaluation, the evaluator developed independent functional tests by examining
design and guidance documentation, examining the developer's test documentation,

executing a sample of the developer's test cases, and creating test cases that augmented the
developer tests. 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 was the following list of EWA-Canada 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. Initialization: The objective of this test goal is to complete the installation and
configuration of the TOE ensuring that the tested TOE is in its evaluated configuration;
c. Identification and Authentication: The objective of this test goal is to ensure that the
identification and authentication requirements have been met;
d. Audit: The objective of this test goal is to ensure that the audit data is recorded and can
be viewed; and
e. Users and Roles: The objective of this test goal is to ensure that the functionality related
to the creation and maintenance of users and roles is correct.
12.3 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:
• Reconnaissance;
• Port Scanning;
• Direct attacks; and
• Misuse.
The independent penetration testing did not uncover any exploitable vulnerabilities in the
anticipated operating environment.
12.4 Conduct of Testing
FTOS 7.8 was subjected to a comprehensive suite of formally documented, independent
functional and penetration tests. The testing took place at the Information Technology
Security Evaluation and Test (ITSET) Facility at EWA-Canada. 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.
