The TOE is Cisco Secure Client - AnyConnect 5.1 for Red Hat Enterprise Linux 8.2 (herein after referred to as the, Cisco Secure Client, VPN client, or the TOE). The TOE enables remote users within an organization to communicate securely as if their devices were directly connected to a private network. The TOE is a VPN Client software application. A virtual private network (VPN) extends the organization’s private network across a shared or public network. A VPN client establishes an IKEv2/IPsec connection to a VPN Gateway allows the remote user to securely connect to the organization’s private network. 3.1 TOE Description The Cisco AnyConnect TOE is a client application that provides remote users a secure VPN tunnel to protect data in transit on both IPv4 and IPv6 networks. The TOE provides IPsec to authenticate and encrypt network traffic travelling across an unprotected public network. By protecting the communication from unauthorized disclosure or modification, remote users can securely connect to an organization’s network resources and applications. 3.2 TOE Evaluated Platforms Detail regarding the evaluated configuration is provided in Section 8 below. 3.3 Physical Boundaries The TOE is a software-only VPN client application. The underlying Linux platform on which the TOE resides is considered part of the IT environment. Cisco Secure Client - AnyConnect 5.1 Validation Report Version 0.4, June 18, 2024 for Red Hat Enterprise Linux 8.2 4 Figure 1: TOE and Environment 4 Security Policy This section summaries the security functionality of the TOE: 1. Cryptographic support 2. User data protection 3. Identification and authentication 4. Security management 5. Privacy 6. Protection of the TSF 7. Trusted path/channels 4.1 Cryptographic support The TOE incorporates a cryptographic module, CiscoSSL FIPS Object Module, to provide the cryptography in support of IPsec with ESP symmetric cryptography for bulk AES encryption/decryption and SHA-2 algorithm for hashing. In addition, the TOE provides the cryptography to support Elliptic-Curve Diffie-Hellman key exchange and the derivation function used in the IKEv2 and ESP protocols. The cryptographic algorithm implementation has been validated for CAVP conformance. The TOE platform provides asymmetric cryptography, which is used by the TOE for IKE peer authentication using digital signature and hashing services. In addition, the TOE platform provides a DRBG. Cisco Secure Client - AnyConnect 5.1 Validation Report Version 0.4, June 18, 2024 for Red Hat Enterprise Linux 8.2 5 4.2 User data protection The TOE platform ensures that residual information from previously sent network packets processed through the platform are protected from being passed into subsequent network packets. 4.3 Identification and authentication The TOE and TOE platform perform device-level X.509 certificate-based authentication of the VPN Gateway during IKE v2 key exchange. Device-level authentication allows the TOE to establish a secure channel with a trusted VPN Gateway. The secure channel is established only after each endpoint successfully authenticates each other. 4.4 Security management The TOE, TOE platform, and VPN Gateway provide the management functions to configure the security functionality provided by the TOE. The TOE provides a Security Administrator role and only the Security Administrator can perform the above security management functions. 4.5 Privacy The TOE does not store or transmit Personally Identifiable Information (PII) over a network. 4.6 Protection of the TSF The TOE performs a suite of self-tests during initial start-up to verify correct operation of its CAVP tested algorithms. Upon execution, the integrity of the TOEs software executables is also verified. The TOE Platform provides for verification of TOE software updates prior to installation. 4.7 Trusted path/channels The TOE’s implementation of IPsec provides a trusted channel ensuring sensitive data is protected from unauthorized disclosure or modification when transmitted from the host to a VPN gateway. 5 Assumptions & Clarification of Scope Assumptions The Security Problem Definition, including the assumptions, may be found in the following documents: • Protection Profile for Application Software, Version 1.4, 07 October 2021 (ASPP14) Cisco Secure Client - AnyConnect 5.1 Validation Report Version 0.4, June 18, 2024 for Red Hat Enterprise Linux 8.2 6 • PP-Module for Virtual Private Network (VPN) Clients, Version 2.4, 31 March 2022 (VPNC24) That information has not been reproduced here and the ASPP14/VPNC24 should be consulted if there is interest in that material. The scope of this evaluation was limited to the functionality and assurances covered in the ASPP14/VPNC24 as described for this TOE in the Security Target. Other functionality included in the product was not assessed as part of this evaluation. All other functionality provided by the devices needs to be assessed separately, and no further conclusions can be drawn about their effectiveness. Clarification of scope All evaluations (and all products) have limitations, as well as potential misconceptions that need clarification. This text covers some of the more important limitations and clarifications of this evaluation. Note that: • As with any evaluation, this evaluation only shows that the evaluated configuration meets the security claims made with a certain level of assurance (the assurance activities specified in the Application Software Protection Profile with the VPNC module and performed by the evaluation team). • This evaluation covers only the specific device models and software as identified in this document, and not any earlier or later versions released or in process. • Apart from the Admin Guide, additional customer documentation for the specific VPN client application models was not included in the scope of the evaluation and therefore should not to be relied upon when configuring or operating the device as evaluated. • This evaluation did not specifically search for, nor attempt to exploit, vulnerabilities that were not “obvious” or vulnerabilities to objectives not claimed in the ST. The CEM defines an “obvious” vulnerability as one that is easily exploited with a minimum of understanding of the TOE, technical sophistication and resources. • The functionality evaluated is scoped exclusively to the security functional requirements specified in the ASPP14/VPNC24 and applicable Technical Decisions. Any additional security related functional capabilities of the TOE were not covered by this evaluation. In particular, the security functionality listed in Section 8.2 of this report is explicitly excluded from the scope of this evaluation. 6 Documentation The following documents were available with the TOE for evaluation: • Cisco Secure Client - AnyConnect 5.1 for Red Hat Enterprise Linux 8.2 CC Configuration Guide, Version 0.3, February 15, 2024 Any additional customer documentation provided with the product, or that is available online was not included in the scope of the evaluation and therefore should not to be relied upon when configuring or operating the device as evaluated.
