MPX 21550, VPX 10, VPX 200, VPX 1000, VPX 3000.
4. The Developer was Citrix Systems Inc.
5. The evaluated configuration of this product is described in this report as the Target of
Evaluation (TOE). Details of the TOE Scope, its assumed environment and the evaluated
configuration are given in Chapter III ‘Evaluated Configuration’ of this report.
6. The NetScaler appliance (i.e. the TOE on one of the above platforms) incorporates three
software components (i.e. ‘the Load Balancer’, the ‘Access Gateway’, and the ‘Web Application
Firewall’) that work together to provide secure access to web-based applications from an
external network.
7. TOE administrators can access the TOE through a direct serial connection, which gives
them access to the Command Line Interface (CLI).
8. The use of authentication servers and a syslog server are optional but, if used, they form
part of the TOE environment.
9. It should be noted that use of Layer 3 routing and management, using the NetScaler GUI
Dashboard Command Center application and NetScaler XML-API interface, is excluded from
the scope of the evaluation. A complete list of features excluded from the scope of evaluation is
2
Hereinafter referred to as ‘NetScaler Version 9.3’ or ‘the TOE’.
CRP267 – Citrix NetScaler Platinum Edition Load Balancer 9.3

provided in the Security Target [ST]. Details of evaluated configuration requirements are
provided in the Evaluated Configuration Guide [CCECG].
10. An overview of the TOE and its product architecture can be found in Chapter IV ‘Product
Architecture’ of this report. Configuration requirements are specified in Section 1 of [ST].
Security Claims
11. The Security Target [ST] fully specifies the TOE’s Security Objectives, the Threats which
these Objectives counter and the Security Functional Requirements (SFRs) and Security
Functionality that elaborate the Objectives. All of the SFRs are taken from CC Part 2 [CC2]; use
of this standard facilitates comparison with other evaluated products.
12. The environmental assumptions related to the operating environment are detailed in
Chapter III (in ‘Environmental Requirements’) of this report.
Evaluation Conduct
13. The TOE’s SFRs and the security environment, together with much of the supporting
evaluation deliverables, remain mostly unchanged from that of Citrix NetScaler Platinum Edition
Load Balancer Version 9.2, which has previously been certified [CR] by the UK IT Security
Evaluation and Certification Scheme to the CC EAL2 assurance level (augmented with
ALC_FLR.2). For the evaluation of Citrix NetScaler Platinum Edition Load Balancer Version
9.3, the Evaluators made some reuse of the previous evaluation results where appropriate.
14. The CESG Certification Body monitored the evaluation which was performed by the
SiVenture Commercial Evaluation Facility (CLEF). The evaluation addressed the requirements
specified in the Security Target [ST]. The results of this work, completed in February 2012,
were reported in the Evaluation Technical Report [ETR].
Conclusions and Recommendations
15. The conclusions of the CESG Certification Body are summarised on page 2 ‘Certification
Statement’ of this report.
16. Prospective consumers of Citrix NetScaler Platinum Edition Load Balancer Version 9.3
should understand the specific scope of the certification by reading this report in conjunction
with the Security Target [ST]. The TOE should be used in accordance with the environmental
assumptions specified in the Security Target. Prospective consumers are advised to check that
the SFRs and the evaluated configuration match their identified requirements, and to give due
consideration to the recommendations and caveats of this report.
17. The TOE should be used in accordance with the supporting guidance documentation
included in the evaluated configuration. Chapter II ‘TOE Security Guidance’ of this report
includes a number of recommendations regarding the secure receipt, installation, configuration
and operation of the TOE.
18. In addition, the Evaluators’ comments and recommendations are as follows:
CRP267 – Citrix NetScaler Platinum Edition Load Balancer 9.3
Page 6 of 23 Issue 1.0 March 2012
• TOE consumers should browse to the https://www.citrix.com/ website to initiate
download of [CCECG], rather than clicking on any URL link to the Citrix website that
they receive, in order to ensure that they are not being redirected to a website that is
masquerading as the Citrix site;
• TOE consumers should adhere closely to the administrative guidance, especially that
provided in [CCECG], in order to maintain and operate the product securely in
accordance with the evaluated configuration.
Disclaimers
19. This report is only valid for the evaluated TOE. This is specified in Chapter III ‘Evaluated
Configuration’ of this report.
20. Certification is not a guarantee of freedom from security vulnerabilities. There remains a
small probability (smaller with higher Evaluation Assurance Levels) that exploitable
vulnerabilities may be discovered after an evaluation has been completed. This report reflects the
CESG Certification Body’s view at the time of certification.
21. Existing and prospective consumers should check regularly for themselves whether any
security vulnerabilities have been discovered since the ETR was issued and, if appropriate,
should check with the Vendor to see if any patches exist for the product and whether those
patches have further assurance.
22. The installation of patches for security vulnerabilities, whether or not those patches have
further assurance, should improve the security of the TOE. However, note that unevaluated
patching will invalidate the certification of the TOE, unless the TOE has undergone a formal re-
certification or is covered under an approved Assurance Continuity process by a CCRA
certificate-authorising Scheme.
23. All product or company names used in this report are for identification purposes only and
may be trademarks of their respective owners.

IV. PRODUCT ARCHITECTURE
Introduction
41. This Chapter gives an overview of the TOE’s main architectural features. Other details of
the scope of evaluation are given in Chapter III ‘Evaluated Configuration’ of this report.
Product Description and Architecture
42. The architecture of the TOE incorporates three software components that work together to
provide secure access to web-based applications. The three software components are:
a. The ‘Load Balancer’ component manages the connections between clients and
servers. Clients establish a connection with the NetScaler, rather than directly with a
server. When the NetScaler receives an application request from a client, it establishes a
connection with the appropriate application server;
b. The ‘Access Gateway’ component is an SSL VPN which provides policy-based
access control for network resources. The Access Gateway allows administrators to
control access based on the identity of the user that is connecting and the device that user is
connecting from;
c. The ‘Web Application Firewall’ component provides firewall protection against
attacks at the Application Layer of the Open Systems Interconnection (OSI) Basic
Reference Model. Traffic which matches a pre-defined signature will be treated as defined
in the signature (this may be any combination of blocking, logging, and maintaining
statistics for matches).
43. The above three components run on top of the Application Delivery Networking Platform
(ADNP) on the appliances. The ADNP is the specialised kernel and packet-processing engine,
which coordinates the operations of the other software components, and it controls the network
interfaces, memory management, and system timing.
TOE Design Subsystems
44. The TOE subsystems, and their security features/functionality, are as follows:
• Kernel Subsystem: coordinates the other subsystems and provides kernel level services;
• Authentication Subsystem: authenticates administrators and VPN users;
• Logging Subsystem: accepts and stores audit events;
• SSL VPN Subsystem: facilitates file-server access and provides access to other file
services, such as print services;
• Application Firewall (AppFW) Learning Subsystem: provides dynamic data firewalling
functionality to protect internal networks from attack;
CRP267 – Citrix NetScaler Platinum Edition Load Balancer 9.3
Page 14 of 23 Issue 1.0 March 2012
• Application Firewall (AppFW) Signature Subsystem: manages signatures that are used
in AppFw for Signature based protections;
• NSDynamic Routing Subsystem: stores and processes routing information for routing
protocols, such as RIP, BGP, and OSPF;
• NS CRL Subsystem: maintains and updates Certificate Revocation Lists (CRLs);
• Access Control Subsystem: controls the actions of administrators. All management
functions must pass through the Access Control Subsystem, which has the ability to
stop unauthorized or unsafe actions;
• Management Subsystem: provides the administrator interfaces and translates
administrator commands;
• Hard Disk Drive (HDD) Subsystem: provides persistent storage for statistics, audit
data, and application firewall data;
• Flash Memory Subsystem: provides storage for the configuration file and SSL
certificate keys.
45. Figure 2 below shows the high-level design subsystems, and their internal and external
interfaces.

TOE Dependencies
46. The TOE dependencies are identified in Chapter III (in ‘Environmental Requirements’) of
this report.
TOE Interfaces
47. The external TOE Security Functions Interface (TSFI), as shown in Figure 2 above, is
described as follows:
• Network Interface: used as the connection point for VPN clients and general network
traffic (e.g. LDAP/HTTP CRL repository);
• Authentication Interface: used for connection to authentication servers;
• External Logging Interface: used for connection to external weblog servers (use of
which is excluded from evaluated configuration) and external syslog servers;
• File Services Interface: used for connection to backend (Samba) servers;

• Command Line Interface (SSH, Telnet5
): used for management;
• SNMP Interface: used to provide status information to monitoring IP devices on the
network.
48. The external interfaces of the TOE shown in Figure 2 above, which are not available in the
evaluated configuration, are:
• GUI Dashboard Command Centre Interface: used for management;
• Apache Interface: used for management (using XML-API or CLI over the
Administrator Workstation connection to the Management Subsystem).
5
The use of Telnet should include adequate protection of the connection, in accordance with A.NetCon in [ST].

51. The Developer’s tests were performed on each distinct physical hardware platform and
also on the VPX-3000 virtualised platform.
52. The Evaluators devised and ran a total of 19 independent functional tests, different from
those performed by the Developer. These tests included penetration tests to address potential
vulnerabilities considered during the evaluation. No anomalies, exploitable vulnerabilities or
errors were detected.
53. The Evaluators’ tests were performed on appliance models MPX 15500-FIPS and MPX
17500, and on virtualised platform VPX-1000, as discussed in Chapter III (in ‘Test
Configuration’) of this report.
54. The Evaluators finished running their penetration tests on 2 February 2012.

Vulnerability Analysis
55. The Evaluators’ vulnerability analysis, which preceded penetration testing and was
reported in [ETR], was based on public domain sources and the visibility of the TOE provided
by the evaluation deliverables, in particular the developer’s vulnerability analysis.
Platform Issues
56. The Citrix NetScaler platforms, which are included within the scope of the TOE, are listed
in Chapter III (in ‘TOE Identification’) of this report. No platform issues were identified.
