1 EXECUTIVE SUMMARY
This report documents the results of the Validation Panel’s oversight of the evaluation of the
Nokia Firewall/VPN Appliances with Check Point VPN-1 Power/UTM NGX R65 product. It
presents the evaluation results, justifications, and the conformance results. This Validation
Report is not an endorsement of the Target of Evaluation (TOE) by any agency of the U.S.
Government and no warranty of the TOE is either expressed or implied.
The evaluation was performed by the Science Applications International Corporation (SAIC)
Common Criteria Testing Laboratory (CCTL) and was completed during November 2012. The
information in this report is largely derived from the Evaluation Technical Report (ETR) written
by SAIC and submitted to the Validation Panel. The evaluation determined that the product
conforms to the Common Criteria Version 2.2, Part 2 extended and Part 3 conformant and meets
the requirements of Evaluation Assurance Level (EAL) 4 augmented with ALC_FLR.3
(Systematic Flaw Remediation).
The Nokia Firewall/VPN Appliances with Check Point VPN-1 Power/UTM NGX R65 is a
network perimeter security device that provides controlled connectivity between two or more
network environments. It mediates information flows between clients and servers located on
internal and external networks governed by the firewall. The TOE provides information flow
controls, including traffic filtering, application-level proxies and intrusion detection and
prevention capabilities. IPSec and SSL VPN functionality encrypts and authenticates network
traffic to and from selected peers, in order to protect the traffic from disclosure or modification
over untrusted networks. Management can be performed either locally or remotely using the
management GUI that is included in the Target of Evaluation (TOE).
The Validation Team provided guidance on technical issues and evaluation processes, reviewed
successive versions of the Security Target, reviewed selected evaluation evidence, reviewed test
plans, reviewed intermediate evaluation results (i.e., the Common Evaluation Methodology
(CEM) work units), and reviewed successive versions of the ETR and test report. The
Validators’ observations support the conclusion that the product satisfies the functional and
assurance requirements defined in the Security Target (ST). Therefore, the Validation Team has
determined that the findings of the evaluation team are accurate, and the conclusions justified.

3 SECURITY POLICY
The explicit TOE security policy consists of the UNAUTHENTICATED SFP that controls the
HTTP and SMTP traffic filter functionality of the firewall, and the AUTHENTICATED SFP that
controls FTP and Telnet traffic filter functionality of the firewall, and the TRAFFIC FILTER
SFP that is applied to all traffic sent through the TOE.
In addition, the TOE implements the following implied security policies:
 Stateful Inspection: security analysis of network traffic at the network layer, and
performing information flow control based on any part of the data being mediated, as
well as on state information. An IDS/IPS capability is integrated with the product’s
traffic-filtering functionality, matching traffic with predefined attack signatures, and
providing recording, analysis, and reaction capabilities.
 Security Servers: inspection of FTP, telnet, HTTP and/or SMTP traffic to verify protocol
conformance
 Virtual Private Network: IPSec and SSL virtual private network gateway
 Audit: generation, storage, analysis and notification of audit events
 Security Management: administrative management and administrator access control
functions
 Secure Internal Communications: protection for management traffic using the TLS
protocol
 Identification and Authentication: authentication of external IT entities, administrators
and users via IKE, TLS, single-use or static passwords.
 TSF Protection: protection mechanisms such as domain separation, packet
defragmentation, self testing, reference mediation and a hardware clock.
8
4 ASSUMPTIONS AND CLARIFICATION OF SCOPE
The following conditions are assumed to exist in the operational environment:
A.PHYSEC The TOE is physically secure.
A.MODEXP The threat of malicious attacks aimed at discovering exploitable
vulnerabilities is considered moderate.
A.GENPUR There are no general-purpose computing capabilities (e.g., the ability to
execute arbitrary code or applications) and storage repository capabilities
on the TOE.
A.PUBLIC The TOE does not host public data.
A.NOEVIL Authorized administrators are non-hostile and follow all administrator
guidance; however, they are capable of error.
A.SINGEN Information can not flow among the internal and external networks unless
it passes through the TOE.
A.DIRECT Human users within the physically secure boundary protecting the TOE
may attempt to access the TOE from some direct connection (e.g., a
console port) if the connection is part of the TOE.
A.NOREMO Human users who are not authorized administrators can not access the
TOE remotely from the internal or external networks1
.
A.REMACC Authorized administrators may access the TOE remotely from the internal
and external networks.
4.1 Operating Environment
Table 2 lists the security functional requirement that must be satisfied by the IT Environment as
presented in the ST.
Table 2 IT Environment Security Functional Requirements
Security Functional Class Security Functional Components
User Data Protection (FDP) FDP_UCT.1.1 Basic data exchange confidentiality
FDP_UIT.1 Data exchange integrity

This assumption means that the TOE does not provide remote services to human users, other than use of identification and
authentication functions. The objective for the non-IT environment O.NOREMO upholds this assumption. Note however that both PPs allow the
TOE to provide a limited number of security functions to remote (identified and authenticated) authorized external IT entities. These are listed in
section Error! Reference source not found. above.

4.2 Clarification of Scope
The Security Target specified the security requirements of the TOE, which determined the scope
of the evaluation. The security requirements allocated to the IT environment have not been
verified as part of the Check Point evaluation—it is the responsibility of the integrator to ensure
the IT environment satisfies those requirements. The IT security services provided by the
environment support the User Data Protection (FDP), the Identification and Authentication
(FIA), and the Trusted Path/Channel (FTP)
There is functionality included in the product which is excluded from the evaluation and is
identified in section 2.4.7 (Functionality Excluded from the TOE Evaluated Configuration) of the
Security Target. The following list is condensed from that section.
 Load Sharing and High Availability
 SmartUpdate
 OPSEC client APIs
 Remote Management via SNMP
 Nokia Network Voyager software management utility
 CLIs and SSH not supported for post-installation administration
 Extended Remote Access VPN Modes (hybrid mode and MS IPSec/L2TP clients)
 LDAP User Management
 Dynamic Routing Protocols
 Transparent Mode
 DShield Storm Center
 Content Inspection

7 IT PRODUCT TESTING
7.1 Vendor Testing
This section describes the testing efforts of the developer and the evaluation team.
7.1.1 Testing Approach
The developer testing approach is described in the ―Check Point VPN-1 Power/UTM NGX R65
Test Documentation.”
The testing of the security functions was performed by a series of automated tests and manual
tests. To ensure test reproducibility, automated tests form the core of the CC tests. Automated
tests always restore the test environment to a known configuration as an initial step. This feature
was used to ensure that manual tests are also reproducible, by performing each test on an
environment that has been generated by running an identified automated test.
The vendor test documentation shows the correspondence between security functions and TSFI.
The vendor test suite demonstrates the security-relevant behavior at the interfaces defined in the
design documentation. The results of the tests demonstrated that the TOE meets the security
functional requirements specified in the Security Target.
The security functions that were tested are the same as those mentioned in the Security Target:
Stateful Inspection, Security Servers, VPN, Audit, Security Management, SIC, Identification &
Authentication, and Protection of the TSF.
7.1.2 Test Descriptions
The vendor test documentation includes detailed test procedures in section 4 of the test
documentation; both automated and manual tests. Each test procedure includes detailed setup
instructions, prerequisites, test steps, and expected results in the body of the test procedures.
The actual results are captured in a separate vendor test document.
The developer tested the interfaces identified in the high level design documentation and mapped
each test to the security function tested. The scope of the developer tests included all TOE
Security Functions. The evaluation team determined that the developer’s actual test results
matched the expected results and witnessed a subset of the tests. Testing consisted of a suite of
automated tests as well as a number of manual tests.
In particular, developer testing contained the following types of tests:
• Stateful Inspection Security Function Tests

management communications,
o Reference Mediation – Demonstrates non-bypassability of traffic mediation
o Hardware Clock – Demonstrates correct timestamping of audit records
o Self Testing – Demonstrates FIPS 140-2 self tests, monitoring of operational status,
and watchdog revival of critical processes.
7.1.3 Depth and Coverage
The amount of testing performed as it relates to the required functionality is described in the
rationale for ATE_COV work units. The depth of testing performed as it relates to the High
Level design is described in the rationale for the ATE_DPT work units in the Evaluation
Technical Report.
7.1.4 Test Results
The actual results are captured in a separate vendor test document. For each description included
in the ―Check Point VPN-1 Power/UTM NGX R65 Test Documentation”, there are actual results
included in the “Check Point VPN-1 Power/UTM NGX R65 Actual Test Results.”
7.2 Evaluator Testing
The evaluation team ensured that the TOE performed as described in the design documentation
and demonstrated that the TOE enforces the TOE security functional requirements. Specifically,
the evaluation team ensured that the developer test documentation sufficiently addresses the
security functions as described in the functional specification. The evaluation team also ensured
that all subsystem interfaces were tested by the developer. The evaluation team performed a
sample of the developer’s test suite, representative of the TOE Security Functions, and devised
an independent set of team tests and penetration tests.
The independent tests run by the evaluation team included the following types of tests:
• Confirming auditing of dropped packets
• Attempting to force residual information from one packet to another by manipulating
packet headers
• Testing the audit resource exhaustion
• Confirming that invalid certificates cannot be used for administrator login
17
Based upon further validation review, the following test cases were added to the vendor test
suite:
 demonstration of the blocking of overlapping IP fragments.
 demonstration of the handling of invalid and large Certificate Revocation Lists (CRL)
18
8 EVALUATED CONFIGURATION
The Nokia IPSO 4.2 Build 051c05 with Check Point VPN-1 Power/UTM NGX R65 HFA 30 is a
software product produced by Check Point. The product is installed on a hardware platform in
combination with an operating system (OS), in accordance with TOE guidance, in a FIPS 140-2
compliant mode.
The TOE consists of the Nokia IPSO 4.2 operating system running Check Point VPN-1
Power/UTM security policy enforcement software, on any of the following hardware platforms:
 IP150
 IP260
 IP290
 IP390
 IP560
 IP690
 IP1220
 IP1260
 IP1280
 IP2450
All models provide an Intel-based CPU as well as memory, disk, local console and network
interface facilities that are tested by Nokia as providing sufficient service and reliability for the
normal operation of the software. A hardware clock/timer with on-board battery backup supports
the operating system in maintaining reliable timekeeping. NICs used by these platforms in the
evaluated configuration (both onboard and add-on) are all based on Intel 825xx family chipsets,
using the if_wx or if_fxp device drivers.
19
9 RESULTS OF THE EVALUATION
The evaluation was conducted based upon CC version 2.2 and CEM version 2.2. The evaluation
determined the Check Point TOE to be Part 2 extended and Part 3 conformant, and that the TOE
meets the Part 3 Evaluation Assurance Level (EAL 4) requirements augmented with
ALC_FLR.3
9.1 Evaluation of the Check Point Security Target (ST) (ASE)
The evaluation team applied each ASE CEM work unit. The ST evaluation ensured the ST
contains description of the environment in terms of policies and assumptions, a statement of
security requirements claimed to be met by the Check Point product that are consistent with the
Common Criteria, and product security function descriptions that support the requirements.
9.2 Evaluation of the CM capabilities (ACM)
The evaluation team applied each EAL 4 ACM CEM work unit. The ACM evaluation ensured
the TOE is identified such that the consumer is able to identify the evaluated TOE. The
evaluation team ensured the adequacy of the procedures used by the developer to accept, control
and track changes made to the TOE implementation, design documentation, test documentation,
user and administrator guidance, security flaws and the CM documentation. The evaluation team
ensured the procedure included automated support to control and track changes to the
implementation representation. The procedures reduce the risk that security flaws exist in the
TOE implementation or TOE documentation.
9.3 Evaluation of the Delivery and Operation documents (ADO)
The evaluation team applied each EAL 4 ADO CEM work unit. The ADO evaluation ensured
the adequacy of the procedures to deliver, install, and configure the TOE securely. The
evaluation team ensured the procedures addressed the detection of modification, the discrepancy
between the developer master copy and the version received, and the detection of attempts to
masquerade as the developer.
9.4 Evaluation of the Development (ADV)
The evaluation team applied each EAL 4 ADV CEM work unit. The evaluation team assessed
the design documentation and found it adequate to aid in understanding how the TSF provides
the security functions. The design documentation consists of a functional specification, a high-
level design document, a low-level design document, and a security policy model. The
evaluation team also ensured that the correspondence analysis between the design abstractions
correctly demonstrated that the lower abstraction was a correct and complete representation of
the higher abstraction.
Additionally, the evaluation team ensured that the security policy model document clearly
describes the security policy rules that were found to be consistent with the design
documentation.
9.5 Evaluation of the Guidance Documents (AGD)
The evaluation team applied each EAL 4 AGD CEM work unit. The evaluation team ensured
20
the adequacy of the user guidance in describing how to use the operational TOE. Additionally,
the evaluation team ensured the adequacy of the administrator guidance in describing how to
securely administer the TOE.
9.6 Evaluation of the Life Cycle Support Activities (ALC)
The evaluation team applied each EAL 4 ALC CEM work unit. The evaluation team ensured the
adequacy of the developer procedures to protect the TOE and the TOE documentation during
TOE development and maintenance to reduce the risk of the introduction of TOE exploitable
vulnerabilities during TOE development and maintenance. The evaluation team ensured the
procedures described the life-cycle model and tools used to develop and maintain the TOE.
The evaluation team also applied the ALC_FLR.3 related work units from the Flaw Remediation
CEM Supplement (Evaluation Methodology, Supplement: ALC_FLR - Flaw Remediation,
Version 1.1, February 2002, CEM-2001/0015R). The evaluation team ensured the developer has
a process to systematically track flaws, document flaws, address flaws, and provide flaw
information to TOE users.
9.7 Evaluation of the Test Documentation and the Test Activity (ATE)
The evaluation team applied each EAL 4 ATE CEM work unit. The evaluation team ensured
that the TOE performed as described in the design documentation and demonstrated that the
TOE security functional requirements are enforced by the TOE. Specifically, the evaluation
team ensured that the vendor test documentation sufficiently addresses the security functions as
described in the functional specification and high level design specification. The evaluation
team performed a sample of the vendor test suite, and devised an independent set of team test
and penetration tests. The results of the vendor tests, team tests, and penetration tests
substantiated the security functional requirements in the ST.
9.8 Evaluation of the Vulnerability Assessment Activity (AVA)
The evaluation team applied each EAL 4 AVA CEM work unit. The evaluation team ensured
that the TOE does not contain exploitable flaws or weaknesses in the TOE based upon the
developer strength of function analysis, the developer vulnerability analysis, the developer
misuse analysis, and the evaluation team’s misuse analysis and vulnerability analysis, and the
evaluation team’s performance of penetration tests.
9.9 Summary of Evaluation Results
The evaluation team’s assessment of the evaluation evidence demonstrates that the claims in the
ST are met. Additionally, the evaluation team’s performance of a subset of the vendor tests
suite, the independent tests, and the penetration test also demonstrated the accuracy of the claims
in the ST.
9.10 Assurance Requirement Results
The assurance requirements for the TOE evaluation are those required by EAL4.
9.10.1 Common Criteria Assurance Components
The CEM work units associated with EAL4 are distributed amongst the ETR sections in chapter
21
15 of the ETR. Collectively, the ETR sections in chapter 15 encompass all CEM work units for
EAL4. Each ETR section includes the CEM work units associated with that ETR section title
(e.g. ACM). Within each ETR section, for each CEM work unit the following is provided:
• Verdict
• Verdict Rationale
The rationale justifies the verdict using the CC, the CEM, and any interpretations and the
evaluation evidence examined. The rationale demonstrates how the evaluation evidence meets
each aspect of the criteria.
The work performed contains a description of the action performed or the method used to apply
the work unit.
9.10.2 Testing and Vulnerability Assessment
In addition to ETR sections the evaluators developed a Test Plan/Report Part to capture the detail
beyond the CEM work unit information. This detail is described within the CEM guidance for
the testing and vulnerability assessment work units. Primarily, the additional detail is focused on
team test procedures, penetration test procedures, results from running the vendor’s sample, and
the justification of running the vendor’s sample.
The evaluation team prepared a Draft of the Test Plan/Report prior to testing that addressed the
selection of vendor tests to run, the team test procedures, and the penetration test procedures.
After performing the test, the Test Report Part was updated to include the actual results from the
vendor sample run and the team test. The Test Report is included in the ―Nokia Firewall/VPN
Appliances with Check Point VPN-1 NGX R65 Part 2 Final ETR Proprietary‖ ETR document,
chapter "Test Report."
9.11 Conclusions
The conclusions for the ST evaluations and the TOE evaluations are addressed below.
9.11.1 ST Evaluation
Each verdict for each CEM work unit in the ASE ETR is a ―PASS‖. Therefore, the Nokia
Firewall/VPN Appliances with Check Point VPN-1 NGX R65 Security Target is a CC compliant
ST.
9.11.2 TOE Evaluation
The verdicts for each CEM work unit in the ETR sections included in chapter 15 are each
―PASS‖. Therefore, the TOE (see below product identification) satisfies the Nokia
Firewall/VPN Appliances with Check Point VPN-1 NGX R65 Security Target, when configured
according to the following guidance documentation:
 CC Evaluated Configuration Installation Guide for Nokia IPSO 4.2, Part No.:
N450000xxx Rev 004, October 2008
9.12 Summary of Evaluation Results
The evaluation team’s assessment of the evaluation evidence demonstrates that the claims in the
ST are met. Additionally, the evaluation team’s performance of a subset of the vendor test suite,
the independent tests, and the penetration test further demonstrated the claims in the ST.

10 VALIDATOR COMMENTS AND RECOMMENDATIONS
The TOE consists of the Nokia IPSO 4.2 operating system running Check Point VPN-1 Power/UTM
security policy enforcement software. As such this report sometimes references Checkpoint
documentation which was used to support this evaluation.
In the evaluated configuration the TOE is a useful product – a traffic filter firewall, application proxy
firewall, intrusion detection system and VPN gateway – and meets the requirements of the Intrusion
Detection System System Protection Profile. A network protection system based on the TOE can be
centrally administered using the SmartConsole application; in the evaluated configuration this requires a
separate management LAN.
The product contains more functionality than was covered by the evaluation, including web-based,
command line and SNMP management, LDAP based user administration, the SmartUpdate online
software upgrade process, failover and load balancing capabilities, and some VPN modes, See section
2.4.7 of the Security Target for more detail on functionality that was omitted from the TOE. During the
evaluation, no evidence was found that pointed to any specific security vulnerabilities associated with the
features that were not evaluated, but since they were not evaluated, and not covered by any claims in the
Security Target, no further conclusions can be drawn about their effectiveness.
The validation team was impressed with the quality of the functional specification for the TOE, it
provided a very thorough and well organized presentation of the required information.
Users must purchase and follow the procedures for Check Point’s Enterprise Software Subscription plan
in order to operate in the evaluated configuration and achieve the systematic flaw remediation
requirements cited in the Security Target. This will enable users to download security patches as they
become available.
The TOE includes a flexible, intuitive and usable management system, including certificate based
administrator authentication, customizable administrator permissions, a graphical user interface, and
support for remote management. The product also includes a standards compliant IKE/IPSec
implementation that may be used in the evaluated configuration, something that not all firewall TOEs
include. The IKE/IPSec implementation was tested by ICSA Labs for the correctness of the protocol
implementation and for interoperability with other VPN products.
This evaluation used evidence and analysis from the evaluation of Check Point VPN-1 Power/UTM NGX
R65 (VID10329), with Check Point's permission and cooperation. The Check Point VPN-1 Power/UTM
NGX R65 evaluation used evidence and analysis from the prior evaluation (VID 10091) of Check Point
VPN-1/Firewall-1 NGX R60, with the changes to the TOE between R60 and R65 receiving the greatest
amount of scrutiny and analysis. The validators worked with the evaluation team to ensure that the
analysis and testing performed for the R65 features was commensurate with EAL4 requirements and the
prior R60 evaluation and that analysis and testing of the R60 features was updated as necessary to reflect
the new product's security functionality. The changes from R60 to R65 include the addition of the SSL
VPN security function (including the inclusion of new TOE components and interfaces) as well as some
updates to the R60 interfaces, including support of Office Mode for IKE and Topology Updates for
remote access IPSec VPN.
