3 Architectural Information
Note: The following architectural description is based on the description presented in the Security
Target.
The TOE is Cisco AnyConnect Secure Mobility Client v4.10 for Red Hat Enterprise Linux 8.1.
The TOE enables remote users within an organization to communicate securely as if their devices
were directly connected to a private network.
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 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 a
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
The evaluated configuration is Cisco AnyConnect v4.10 installed on Red Hat Enterprise Linux
8.1.
3.2 Physical Boundaries
The TOE is a software-only VPN client application. The underlying Red Hat Enterprise Linux 8.1
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
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
Cisco AnyConnect Secure Mobility Client v4.10 Validation Report Version 0.2, July 18, 2022
for Red Hat Enterprise Linux 8.1
4
used in the IKEv2 and ESP protocols. The cryptographic algorithm implementation has been
validated for Cryptographic Algorithm Validation Program (CAVP) conformance. See Table 15
in the CAVP Certificates Section of the Security Target for certificate references.
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 Deterministic Random Bit Generator (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
Assumptions
The Security Problem Definition, including the assumptions, may be found in the following
documents:

• Protection Profile for Application Software, Version 1.3, 1 March 2019
(PP_APP_V1.3PP_APP_V1.3)
• PP-Module for Virtual Private Network (VPN) Clients, version 2.3, 10 August 2021
(MOD_VPNC_V2.3MOD_VPNC_V2.3)
That information has not been reproduced here and the PP_APP_V1.3/MOD_VPNC_V2.3 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
PP_APP_V1.3/MOD_VPNC_V2.3 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 Module for Virtual Private Network
Clients 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 Virtual
Private Network, Application Software 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 PP_APP_V1.3/MOD_VPNC_V2.3 and applicable Technical Decisions.
Any additional security related functional capabilities of the TOE were not covered by this
evaluation.
