Guidance Documents: The evaluators examined the JUNOS® 10.4R5 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 JUNOS® 10.4R5 configuration management system
and associated documentation was performed. The evaluators found that the JUNOS®
10.4R5 configuration items were clearly marked and that the access control measures as
described in the configuration management documentation are effective in preventing
unauthorized access to the configuration items. The developer’s configuration management
system was also observed during the site visit, and it was found to be mature and well-
developed.
During the site visit the evaluators examined the development security procedures and
determined that they detailed sufficient security measures for the development environment
to protect the confidentiality and integrity of the JUNOS® 10.4R5 design and
implementation. The evaluators confirmed that the developer used a documented model of
the TOE life-cycle and that the life-cycle model provides for the necessary control over the
development and maintenance of the TOE.
The evaluators examined the delivery documentation and determined that it described all of
the procedures required to maintain the integrity of JUNOS® 10.4R5 during distribution to
the consumer.
The evaluators reviewed the flaw remediation procedures used by Juniper Networks, Inc. for
the JUNOS® 10.4R5. During a site visit, the evaluators 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.
Vulnerability assessment: The evaluators conducted an independent vulnerability analysis
of JUNOS® 10.4R5. Additionally, the evaluators conducted a review of public domain
vulnerability databases, and a search of all evaluation deliverables. The evaluators identified
potential vulnerabilities for testing applicable to JUNOS® 10.4R5 in its operational
environment.
All these evaluation activities resulted in PASS verdicts.
11 ITS Product Testing
Testing at EAL 3 consists of the following three steps: assessing developer tests, performing
independent functional tests, and performing penetration tests.

11.1 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 and depth analysis and found them to
be complete and accurate. The correspondence between the tests identified in the developer’s
test documentation and the functional specification and TOE design was complete.
11.2 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 is the
following list of CGI IT Security Evaluation & Test Facility 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. Log in TOE as super user: The objective of this test goal is to demonstrate that an
authorized user with super-user class privileges can manage the TSF by making
configuration changes on the TOE;
c. Verify audit records for valid user name and invalid password: The objective of this test
goal is to demonstrate failed login attempts will generate an audit record in the syslog;
d. Unauthorized user cannot modify audit logs: The objective of this test goal is to
demonstrate that only the root and super-user roles can modify the audit logs;
e. TOE drops invalid IP packets: The objective of this test goal is to demonstrate that
invalid IP packets are dropped by the TOE;
f. Throttle SSH connection: The objective of this test goal is to demonstrate that the TOE
introduces incremental delays for each consecutive failed login; and

g. Management traffic flow into TOE using in-band management port: The objective of this
test goal is to demonstrate management traffic sent to the TOE using the in-band
management port is processed correctly.
11.3 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. Port Scanning: The objective of this test was to scan the TOE using a port scanner to
determine what ports were open and what services were running;
b. Denial of Service: The objective of this test is to determine if TOE is susceptible to a
known vulnerability (PSN-2012-01-472) by receiving Border Gateway Protocol (BGP)
UPDATE with malformed PATH attribute. The second portion of this test is to determine
whether the workaround solution provided by the developer mitigates this vulnerability;
c. Exhaust Audit Log: The objective of this test is to send enormous amount of network
traffic to exhaust the audit log causing possible adverse effects;
d. Overflow Content Addressable Memory (CAM) table3
: The objective of this test is to
send high volume of invalid Media Access Control (MAC) addresses to the TOE in order
to overflow the CAM table causing the TOE to behave like a hub; and
e. Unexpected TOE Reboot: The objective of this test is to reboot the TOE unexpectedly
(simulate a system crash) and determine if any potential vulnerabilities are found.
The independent penetration testing did not uncover any exploitable vulnerabilities in the
intended operating environment.
11.4 Conduct of Testing
JUNOS® 10.4R5 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 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.
