3 Architectural Information
Note: The following architectural description is based on the description presented in the
Security Target.
The TOE is the Cisco AnyConnect Secure Mobility Client for Apple iOS (herein after
referred to as the VPN client, or the TOE). The TOE provides remote users with secure
IPsec (IKEv2) VPN connections to the Cisco 5500 Series Adaptive Security Appliance
(ASA) VPN Gateway allowing installed applications to communicate as though connected
directly to the enterprise network.
The TOE is a remote access application that execute on a mobile platform and provides a
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.
3.1 TOE Evaluated Platforms
The TOE is a mobile VPN client application executing on an iPhone mobile device
platform. It requires one of the following Common Criteria certified mobile platforms:
 Apple iPhone 7/7 Plus running iOS 11.2
Refer to the Apple iOS on iPhone and iPad Devices Security Target1
for information
regarding the evaluated configuration requirements.
3.2 TOE Architecture
The TOE requires the following IT Environment Components when the TOE is configured
in its evaluated configuration:
Component Usage/Purpose Description
Certificate Authority A Certificate Authority is used to provide valid digital certificates.

Component Usage/Purpose Description
ASDM Management
Platform
The ASDM 7.6 operates from any of the following operating systems:
 Windows 7, 8
 Apple OS X 10.4 or later
 Red Hat Enterprise Linux 5 (GNOME or KDE)
Note that that ASDM software is installed on the ASA appliance and the management
platform is used to connect to the ASA and run the ASDM. The only software
installed on the management platform is a Cisco ASDM Launcher.
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 as the underlying platform
provides some of the security functionality required in the VPNv1.4 Client PP, which is
denoted with the phrase “TOE Platform” in the Security Target.
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. Protection of the TSF
6. Trusted path/channels
4.1 Cryptographic support
The TOE provides 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 derivation function
used in the IKEv2 and ESP protocols. The cryptographic algorithm implementation has
been validated for CAVP conformance as part of the platform evaluation (VID10851).
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.
Cisco AnyConnect Secure Validation Report Version 0.3, June 4, 2018
Mobility Client for Apple iOS

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.
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 also verified.
The TOE Platform provides for verification of TOE software updates prior installation.
4.6 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
The Security Problem Definition, including the assumptions, may be found in the following
document:
 Protection Profile for IPsec Virtual Private Network (VPN) Clients, Version 1.4, 21
October 2013
That information has not been reproduced here and the IVPNCPP14 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
IVPNCPP14 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
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 Protection Profile for IPsec Virtual Private Network (VPN)
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.
 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 IVPNCPP14 and applicable Technical Decisions. Any
additional security related functional capabilities of the TOE were not covered by this
