The Target of Evaluation (TOE) is the Samsung Electronics Co., Ltd. Samsung Galaxy Note 5 & Galaxy Tab S2 VPN Client.
\r\nThe TOE is a VPN client that runs on a mobile operating system based on Android with modifications made to increase the level of security provided to end users and enterprises. The TOE is intended to be used as part of an enterprise messaging solution providing mobile staff with enterprise connectivity.
\r\nThe TOE includes a Common Criteria mode (or “CC mode”) that an administrator can invoke through the use of an MDM or through the installation and use of the administrative application, CCMode.apk (see the Guidance for instructions to obtain the application). The TOE must be configured as follows in order for an administrator to transition the TOE to CC mode.
· Require a screen lock password (swipe, PIN, pattern, or facial recognition screen locks are not allowed).
· The maximum password failure retry policy should be less than or equal to ten.
· Device encryption must be enabled.
· Revocation checking must be enabled.
When CC mode has been enabled, the TOE behaves as follows.
· The TOE restricts the available VPN configurations to those evaluated as part of this evaluation.
· The TOE restricts the use of IKEv1 and IKEv2 IPsec cipher suites to only those conformant with the requirements of the IVPNCPP14.
The evaluated configuration consists of the following device identification:

","environmental_strengths":"The logical boundaries of the Samsung Galaxy Note 5 & Galaxy Tab S2 VPN Client TOE are realized in the security functions that it implements. Each of these security functions is summarized below.
\r\nCryptographic Support - The IPsec implementation is the primary function of the TOE. IPSec is used by the TOE to protect communication between itself and a VPN Gateway over an unprotected network. With the exception of the IPsec implementation, the TOE relies upon its underlying platform (evaluated against the Protection Profile For Mobile Device Fundamentals) for the cryptographic services.
\r\nUser Data Protection - The TOE ensures that residual information is protected from potential reuse in accessible objects such as network packets.
\r\nIdentification and Authentication - The TOE provides the ability to use, store, and protect X.509 certificates and pre-shared keys that are used for IPsec Virtual Private Network (VPN) connections.
\r\nSecurity Management - The TOE provides all the interfaces necessary to manage the security functions identified throughout this Security Target. In particular, the IPsec VPN is fully configurable by a combination of functions provided directly by The TOE and those available to the associated VPN gateway.
\r\nTSF Protection - The TOE relies upon its underlying platform to perform self-tests that cover the TOE as well as the functions necessary to securely update the TOE.
\r\nTrusted Path/Channels - The TOE acts as a VPN client using IPsec to established secure channels to corresponding VPN gateways.
