3 Architectural Information
Note: The following architectural description is based on the description presented in the
Security Target.
The TOE is Cisco Secure Client - AnyConnect 5.0 for Android 12 (herein after referred to as
the 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 allowing the remote user to securely connect to the
organization’s private network.
3.1 TOE Evaluated Platforms
Detail regarding the evaluated configuration is provided in Section 8 below.
3.2 TOE Architecture
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.
The TOE only works with a Cisco Adaptive Security Appliance (ASA) VPN gateway. The
appropriate licenses must be installed on the ASA to permit use of AnyConnect remote access
IPsec VPN. Refer to the Cisco License Management portal at http://www.cisco.com/go/license.
FIPS mode must be enabled on both the ASA VPN gateway as well as the TOE application.
3.3 Physical Boundaries
The TOE is a software-only VPN client application. The underlying mobile platform on which
the TOE resides is considered part of the IT 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
Cisco Secure Client - AnyConnect 5.0 Validation Report Version 0.3, July 26, 2023

4.1 Cryptographic support
The TOE incorporates a cryptographic module, CiscoSSL FIPS Object Module version 7.2a
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 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.
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
5.1 Assumptions
The Security Problem Definition, including the assumptions, may be found in the following
documents:
• Protection Profile for Application Software, Version 1.4, 7 October 2021 (ASPP14)
• 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.
5.2 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.
