PP OVERVIEW

The US Government Virtual Private Network (VPN) Boundary Gateway Protection Profile (PP) for Medium Robustness Environments was generated under the Enclave Boundary Security Technologies and Solutions (EBST&S) Support Program, sponsored by the National Security Agency (NSA). This PP is intended to be used as follows:

• For product vendors and security product evaluators, this PP defines the requirements that must be addressed by specific products as documented in vendor Security Targets (STs).
• For system integrators, this PP is useful in identifying areas that need to be addressed to provide secure system solutions. By matching the PP with available STs, security gaps may be identified and products or procedures may be configured to bridge these gaps.

This PP specifies the minimum-security requirements for VPN devices (hereafter referred to as the Target of Evaluation (TOE)) used by the Department of Defense (DoD) in Medium Robustness Environments. The target robustness level of "medium" is specified in discussed in section 3.0 of this PP.

The TOE may consist of one or more devices that act as part of an organization's overall security defense by encrypting traffic flowing between enclaves that are geographically separated. If the security policy specifies encryption, the TOE automatically encrypts all outgoing traffic from the enclave when it is destined for another enclave having the same security policy. If the security policy does not specify encryption, all outgoing traffic will be sent unencrypted. The TOE decrypts incoming traffic to the enclave when that traffic has been encrypted at the originating enclave.

The TOE supports identification and authentication for the administrative roles (I&A). The TOE shall generate audit data of security relevant events and will meet the medium assurance requirements as described in section 5.3 of this PP.

This PP defines:

• assumptions about the security aspects of the environment in which the TOE will be used;
• threats that are to be addressed by the TOE;
• security objectives of the TOE and its environment;
• functional and assurance requirements to meet those security objectives; and
• rationale demonstrating how the requirements meet the security objectives

ENVIRONMENTAL STRENGTHS

The evaluation of the US Government Virtual Private Network (VPN) Boundary Gateway Protection Profile (PP) for Medium Robustness Environments, Version 1.1 provides specification for environments in which TOEs with various levels of robustness are appropriate to meet Medium Robustness level of independently assured security requirements. The assurance requirements were chosen to be consistent with this goal.

ASSURANCE MAINTENANCE

July 25, 2007
Assurance maintenance has been performed on this protection profile to update it to the common criteria version 3.1. This update caused a change in version number (from 1.0 to 1.1) that indicates an update has occurred. The updates included revisions based on the assurance requirements of the CC 3.1, removal of FPT_SEP and FPT_RVM since it is now covered by ADV_ARC and replacement of Explicitly stated requirements with Extended requirements (only the nomenclature changed and not the requirements.)  Cryptographic functional requirements were also revised to reflect the latest updated standards. 

This Validated Protection Profile is not assigned to any Validated Products
