3 Architectural Information
Note: The following architectural description is based on the description presented in the
Security Target.
Cisco AnyConnect 4.7 on Windows Validation Report Version 0.3, July 15, 2019
3
The TOE is the Cisco AnyConnect Secure Mobility Client v4.7 for Windows 10 (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 which allowing 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. The TOE only
works with a Cisco Adaptive Security Appliance (ASA) VPN gateway.
3.2 TOE Evaluated Configuration
As a software application, the evaluated configuration is Cisco AnyConnect v4.7 installed on
Windows 10 Pro remote client that connects to a Cisco ASA 5500-X running software version
9.1 or later, which functions as the VPN head-end gateway. Refer to the Common Criteria
Administrator’s Guide for instructions on installing and configuring the TOE.
A typical TOE deployment scenario:

3.3 Physical Scope of the TOE
The TOE is a software-only VPN client application. The underlying Windows 10 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. Full Residual Information Protection
3. Identification and Authentication
4. Security Management
5. Protection of the TSF
6. Trusted 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. The TOE provides the cryptography
to support Diffie-Hellman key exchange and derivation functions 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. The TOE platform
provides a DRBG.
4.2 Full residual information protection
As packets are processed by the TOE, the TOE platform ensures that any residual information
which may be contained in previously transmitted network packets is prevented 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
Cisco VPN Gateway during IKE v2 key exchange. Device-level authentication allows the TOE
to establish a secure channel with a trusted Cisco VPN Gateway. The secure channel is
established only after each endpoint successfully authenticates with another endpoint.
4.4 Security management
The TOE, TOE platform, and VPN Gateway provide the management functions necessary to
configure the security functionality provided by the TOE.
Cisco AnyConnect 4.7 on Windows Validation Report Version 0.3, July 15, 2019

4.5 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 TOE’s software executables is
verified. Upon installation of a TOE update, a digital signature verification check is
automatically performed to ensure the update has not been modified since distribution. The
TOE platform provides for verification of TOE software updates prior to installation.
4.6 Trusted channels
The TOE’s implementation of IPsec provides a trusted channel to ensure sensitive data is
protected from unauthorized disclosure or modification when the data is transmitted from the
host to the compatible Cisco VPN gateway.
5 Assumptions
The Security Problem Definition, including the assumptions, may be found in the following
documents:
 Protection Profile for Application Software, version 1.2, April 22, 2016
 PP-Module for Virtual Private Network (VPN) Clients, version 2.1, October 5, 2017
That information has not been reproduced here, and the ASPP12/VPNC21 should be consulted
if there is interest in that material.
The scope of this evaluation was limited to the security functionality and assurances covered in
the ASPP12/VPNC21 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.
6 Clarification of Scope
All evaluations (and all products) have limitations, as well as potential misconceptions that
could benefit from 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 ASPP12/VPNC21 and performed by the evaluation team).
 This evaluation covers only the specific software as identified in this document, and not
any earlier or later versions released or in process.
 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
Cisco AnyConnect 4.7 on Windows Validation Report Version 0.3, July 15, 2019
6
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 ASPP12/VPNC21 and applicable Technical Decisions.
Any additional security related functional capabilities of the TOE were not covered by
this evaluation.
7 Documentation
