Executive Summary
Riverbed Cascade Profiler v9.6 (hereafter referred to as Cascade Profiler v9.6), from
Riverbed Technology, is the Target of Evaluation (TOE) for this Evaluation Assurance Level
(EAL) 3 augmented evaluation.
Cascade Profiler v9.6 is a software-only TOE which collects network flow and packet data
and uses it to discover applications and track their performance. Administrators are alerted if
there are any deviations from normal behavior. To troubleshoot a problem, authorized users
can drill down through multi-resolution views, from macro flows at the top level for
executive-level reporting, through application-level flows to micro flows (packet-based
views) and full packet captures. An authorized user can also view a full graphical
representation of network assets and their dependencies. These views help managers address
critical IT challenges, such as network monitoring and troubleshooting, application
performance, security threats and Wide Area Network (WAN) optimization and analysis.
EWA-Canada is the CCEF that conducted the evaluation. This evaluation was completed on
07 February 2013 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
made during the evaluation, the intended environment for Cascade Profiler v9.6, the security
requirements, and the level of confidence (evaluation assurance level) to which it is asserted
that the product satisfies its security requirements. Consumers are advised to verify that their
operating environment is consistent with that specified in the security target, and to give due
consideration to the comments, observations and recommendations in this certification
report.
The results documented in the Evaluation Technical Report (ETR)1
for this product provide

1 Identification of Target of Evaluation
The Target of Evaluation (TOE) for this Evaluation Assurance Level (EAL) augmented
evaluation is Riverbed Cascade Profiler v9.6 (hereafter referred to as Cascade Profiler v9.6),
from Riverbed Technology.
2 TOE Description
Cascade Profiler v9.6 is a software-only TOE which collects network flow and packet data
and uses it to discover applications and track their performance. Administrators are alerted if
there are any deviations from normal behavior. To troubleshoot a problem, authorized users
can drill down through multi-resolution views, from macro flows at the top level for
executive-level reporting, through application-level flows to micro flows (packet-based
views) and full packet captures. An authorized user can also view a full graphical
representation of network assets and their dependencies. These views help managers address
critical IT challenges, such as network monitoring and troubleshooting, application
performance, security threats and WAN optimization and analysis.
Cascade Profiler v9.6 is separated into three components briefly described as follows:
 Cascade Profiler v9.6 software application - performs the actual analysis of network
traffic and data;
 Cascade Sensor - used to gather data from the network and users. The Sensors retrieve
and analyze actual network traffic on the wire; and
 Cascade Gateway - collects network flows from infrastructure devices, combines them,
and performs some limited pre-processing, encrypts the data, and then reports it to the
Profilers.
Each product component can be deployed separately as a Profiler, Sensor, or Gateway or can
be deployed as an all-in-one device that runs all of the TOE components on one machine.
The TOE supports secure communication between distributed TOE components and between
the TOE and its remote administrators using FIPS 140-2 validated cryptography.

10 Evaluation Analysis Activities
The evaluation analysis activities involved a structured evaluation of Cascade Profiler v9.6,
including the following areas:
Development: The evaluators analyzed the Cascade Profiler v9.6 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
Cascade Profiler v9.6 security architectural description and determined that the initialization
process is secure and that the security functions are protected against tamper and bypass. The
evaluators also independently verified that the correspondence mappings between the design
documents are correct.
Guidance Documents: The evaluators examined the Cascade Profiler v9.6 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 Cascade Profiler v9.6 configuration management
system and associated documentation was performed. The evaluators found that the Cascade
Profiler v9.6 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 Cascade Profiler v9.6 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 Cascade Profiler v9.6 during distribution
to the consumer.
The evaluators reviewed the flaw remediation procedures used by Riverbed Technology for
Cascade Profiler v9.6. During a site visit, the evaluators examined the evidence generated by
adherence to the procedures. The evaluators concluded that the procedures are adequate to
CCS Certification Report Riverbed Technology

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 Cascade Profiler v9.6. 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 Cascade Profiler v9.6 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 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. Web Interface Access: The objective of this test case is to verify that logins to the web
interface can be restricted to specific IP addresses;

c. Concurrent Logins: The objective of this test case is to verify that multiple concurrent
logins through the web interface with the same user is disallowed; and
d. Unintended Power Loss: The objective of this test case is to verify that changes made to
TSF data just before an unintended power loss will not remain intact if not confirmed.
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 Scan: The objective of this test goal is to scan the TOE using a port scanner to reveal
any potential avenues of attack;
b. Vulnerability Identification: The objective of this test goal is to scan the TOE for
vulnerabilities using automated scanning tools; and
c. Information Leakage Verification: The objective of this test goal is to monitor the TOE
for leakage during start-up, shutdown, login, and other scenarios using a packet sniffer.
The independent penetration testing did not uncover any exploitable vulnerabilities in the
intended operating environment.
11.4 Conduct of Testing
Cascade Profiler v9.6 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.
11.5 Testing Results
The developer’s tests and the independent functional tests yielded the expected results,
giving assurance that Cascade Profiler v9.6 behaves as specified in its ST and functional
specification and TOE design.
12 Results of the Evaluation
This evaluation has provided the basis for an EAL 3+ level of assurance. The overall verdict
for the evaluation is PASS. These results are supported by evidence in the ETR.
