Executive Summary
Owl DualDiode Communication Cards v7 (hereafter referred to as Owl DualDiode v7), from
Owl Computing Technologies, Inc., is the Target of Evaluation. The results of this evaluation
demonstrate that Owl DualDiode v7 meets the requirements of Evaluation Assurance Level
(EAL) 2 for the evaluated security functionality.
Owl DualDiode v7 is a product that allows information to flow one-way-only. The TOE
provides an absolute one-way unidirectional flow of any data and information between a
source domain, the sending host system or network to a destination domain, and the receiving
host system or network. The TOE also employs a proprietary transport protocol which
ensures a non-routable, true protocol break to prevent any back channel or covert channel
security threat. The combined features of the TOE protect the destination host or network
from any potential leaks of information or potential network probing attacks.
CSC Security Testing/Certification Laboratories is the CCEF that conducted the evaluation.
This evaluation was completed on 23 December 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

6 Assumptions and Clarification of Scope
Consumers of Owl DualDiode v7 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:
 Authorized personnel that possess the necessary privileges to access the secure side
information shall install, administer and use the TOE by adhering to the security
policies and practices regarding the usage of the TOE; and
 Authorized personnel shall ensure the TOE is delivered, installed and administered in
a manner that maintains security. The appropriate security authority shall accredit
the installation of the TOE.
6.2 Environmental Assumptions
The following Environmental Assumptions are listed in the ST:
 Information cannot flow between the source network and destination network without
going through the TOE. This prevents a threat agent from circumventing the security
being provided by the TOE through an untrustworthy product;
 The TOE will be installed so only relevant network traffic will flow through the TOE
and hence be subject to the organizational security policy; and
 The TOE and its operating environment will be physically protected to a degree
commensurate with the value of the information it is intended to protect.

9 Evaluation Analysis Activities
The evaluation analysis activities involved a structured evaluation of Owl DualDiode v7,
including the following areas:
Development: The evaluators analyzed the Owl DualDiode v7 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 Owl
DualDiode v7 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 Owl DualDiode v7 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 Owl DualDiode v7 configuration management system
and associated documentation was performed. The evaluators found that the Owl DualDiode
v7 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 Owl DualDiode v7 during distribution to
the consumer.
The evaluators reviewed the flaw remediation procedures used by developer for the Owl
DualDiode v7. During a site visit, the evaluators also examined the evidence generated by
adherence to the procedures.
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. Forward transfer function: The objective of this test goal is to confirm that the TOE can
send information from its send-only optical interface to the receive-only optical interface
on the other instance of the TOE;
c. Forward transfer without Fiber: The objective of this test goal is to confirm that no
information will flow between two instances of the TOE when the fibre cable is removed;
d. Software change: The objective of this test goal is to confirm that the TOE is not
dependent on the underlying software for one-way transfer of information between two
instances of the TOE; and
e. Physical breach: The objective of this test goal is to confirm that no information flows
occur between the send and receive sides of the TOE when there is a physical breach in
the connection.

independent functional and penetration tests. The testing took place at the Information
Technology Security Evaluation and 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 Owl DualDiode v7 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.
