5 Common Criteria Conformance
The evaluation was conducted using the Common Methodology for IT Security Evaluation,
Version 1.0, for conformance to the Common Criteria for IT Security Evaluation, version 2.1
incorporating all final interpretations issued prior to 23 May 2003. The ECMS is:
a) Common Criteria Part 2 conformant, with security functional requirements based
only upon functional components in Part 2;
b) Common Criteria Part 3 conformant, with security assurance requirements based
only upon assurance components in Part 3; and
c) Common Criteria EAL 3 conformant, with all the security assurance requirements in
the EAL 3 package.
6 Security Policy
The ECMS Security Policy states the rules by which the ECMS manages communications
resources. The complete ECMS Security Policy is identified in the ST. The following
statements are representative of the ECMS Security Policy:
Identification and Authentication. Users of the ECMS are required to successfully identify
and authenticate before they are granted access to the functional aspects of the software.
Access Control. The ECMS implements and enforces a discretionary access control
environment. Within this environment, each user’s access to controlled peripherals and
components within the application is determined by the user’s assigned role. The ECMS
controls access to radio equipment such as HF transmitters, HF receivers, V/UHF
transceivers and modems and the radio services supported by this equipment offering voice
and data communication services.
Audit. The audit component of the ECMS generates audit logs upon use of the identification
and authentication mechanisms, upon performance of an operation on an object covered by
the ECMS Security Policy and upon performance of preset actions taken due to exceeding of
a set threshold, e.g. audit log exceeding 80% capacity. The audit records are protected by
ensuring that only authorized users have access to the audit records. The audit records are
protected from deletion, modification and system failures.
7 Assumptions and Clarification of Scope
Consumers of the ECMS should consider assumptions about usage and environmental
settings as requirements for the product’s installation and its operating environment. This
will help to ensure the proper and secure operation of the ECMS.

Version 4.1
7.1 Secure Usage Assumptions
For purposes of this evaluation, the users are assumed to be trusted and to understand the
correct usage of the system. The users must operate the ECMS following the guidance in
the ECMS Operating Instructions.
7.2 Environmental Assumptions
The following assumptions are made about the operating environment of the ECMS:
a) The components of the ECMS will be located within controlled access facilities
which will prevent unauthorised physical access;
b) Administrators are non-hostile and will not attempt to compromise the ECMS
functionality; and
c) Logical and physical protection will be provided for the communications with
peripheral devices.
For more information about the ECMS security environment, refer to Section 3 of the ST.
7.3 Clarification of Scope
The ECMS provides a level of protection that is appropriate for an assumed non-hostile and
well-managed user community. While it is designed to protect its user community against
inadvertent or casual attempts to breach system security, it is not intended for situations in
which determined attempts by hostile and well-funded attackers use sophisticated attacks to
violate system security, particularly from within the physical zone or domain of deployment.
8 Architectural Information
The ECMS is a software application that resides on a PC running the Windows NT®
operating system. Users interface with the application via the PC’s keyboard and display.
The Target of Evaluation (TOE) is denoted in figure 2.1 of the ST as the ECMS Core, and
comprises the following subsystems:
a) HOST, that provides management of security and other basic services for other
subsystems;
b) Service Manager, that is used to manage a set of communication services using the
resources and services managed by the lower level subsystems;

c) Delegation Manager, that delegates the remote control of remote controllable
equipment to Delegate Managers; and
d) Agent Manager XXX, that manages remote controllable equipment.
9 Evaluated Configuration
The TOE is evaluated under the same configuration as indicated in the ST, except that no
radio equipment which the TOE is designed to command was available due to transportation
constraints.
The ECMS Host application runs on a Microsoft® Windows NT4® PC. The following
software is used by the ECMS Host application:
ƒ JDK™ 1.2.2
ƒ EXCEED®
ƒ Microsoft® Windows NT® 4 Service Pack 6a
ƒ INGRES® II.
10 Documentation
The documentation for the ECMS consists of ECMS Operating Instructions (Issue 06/2004)
which is described in Section 11 below.
11 Evaluation Analysis Activities
The evaluation analysis activities involved a structured evaluation of the ECMS, including
the following areas:
Configuration management: An analysis of the ECMS development environment and
associated documentation was performed. The evaluators found that the ECMS configuration
items were clearly marked, and could be modified and controlled. The developer’s
configuration management system (Rational® ClearCase®) was observed during a site visit,
and was found to be mature and well developed. In particular, the developer uses an
integrated suite of commercial tools to perform software configuration management and
problem tracking.
Secure delivery and operation: The evaluators examined the delivery documentation and
determined that it described all of the procedures required to maintain the integrity of the
ECMS during distribution to the consumer. The evaluators examined the installation,
generation and start-up procedures, and determined that they were complete and sufficiently
detailed to result in a secure configuration.

Version 4.1
Design documentation: The evaluators analysed the ECMS functional specification and
high-level design; they determined that the documents were internally consistent, and
completely and accurately instantiated all interfaces and security functions. The evaluators
also independently verified that the correspondence mappings between the design documents
were correct.
Guidance documents: The evaluators examined the ECMS Operating Instructions
document and determined that it sufficiently and unambiguously described how to securely
use and administer the product, and that it was consistent with the other documents supplied
for evaluation. The ECMS Operating Instructions document includes both the user and
administrator manuals.
Life-cycle support: The evaluators assessed the development security procedures during a
site visit and determined that the procedures detailed sufficient security measures for the
development environment to protect the confidentiality and integrity of the ECMS design
and implementation.
Vulnerability assessment: The ECMS Security Target’s claims for the strength of function
claims were validated through independent evaluator analysis. The evaluators examined the
developer's vulnerability analysis, and found that it sufficiently described each of the
potential vulnerabilities along with sound rationale as to why it was not exploitable in the
intended environment. Additionally, the evaluators conducted an independent review of
public domain vulnerability databases, and all evaluation deliverables to provide assurance
that the developer had considered all potential vulnerabilities.
All these evaluation activities resulted in PASS verdicts.
12 ITS Product Testing
Testing at EAL3 consists of the following three steps: assessing developer tests, performing
independent functional tests, and performing independent vulnerability tests.
12.1 Assessing Developer’s Tests
The evaluators verified that the developer had met their testing responsibilities by examining
their test evidence, and reviewing their test results, as documented in the Evaluation
Technical Report (ETR)2
.
The evaluators analyzed the developer’s test coverage analysis and test depth analysis, and
found it to be complete and accurate. The correspondence between tests identified in the

developer’s test documentation and the functional specification and high-level design was
complete.
12.2 Independent Functional Testing
During this evaluation, the evaluators developed independent functional tests by examining
the 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.
Independent functional testing focused on the ECMS Security Policy, specifically:
a) Testing that User Interfaces and User Roles corresponded;
b) Access control testing;
c) Testing of audit;
d) Abstract machine testing; and
e) Consequence of successive failed login attempts.
12.3 Independent Penetration Testing
Subsequent to the examination of the developer’s vulnerability analysis and test activities,
limited independent evaluator penetration testing was conducted. Penetration testing did not
uncover any exploitable vulnerabilities for the ECMS in the anticipated, restrictive operating
environment.
12.4 Conduct of Testing
The ECMS was subjected to a comprehensive suite of formally-documented, independent
functional tests. The testing took place at the DOMUS IT Security Laboratories located in
Ottawa, Ontario. 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 the ETR.
