PP OVERVIEW

This U.S. Government Traffic-Filter Firewall Protection Profile For Medium Robustness Environments specifies the minimum-security requirements for network boundary devices that provide controlled connectivity between two or more network environments (hereafter referred to as the Target of Evaluation (TOE)) used by the Department of Defense (DoD) in Medium Robustness Environments.  The TOE may be a dedicated device such as a firewall, or an enhancement to some other network device such as a router.  The target robustness level of "medium" is discussed in Section 3.0 of this PP.

The TOE supports user identification and authentication (I&A) where "useR" is defined to be a human user acting in a role (i.e., Security Administrator, Cryptographic Administrator, and Audit Administrator) or an authorized IT entity.  The TOE provides the capability to pass and block information flows based on a set of rules defined by the Security Administrator.  The TOE supports encryption for remote administration and authorized IT entities (e.g., certificate server, NTP server), and generates audit data of security relevant events.

The assurance requirements are presented in Section 5.3.

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, and how the security objectives address the threats.

ENVIRONMENTAL STRENGTHS

The evaluation of the U. S. Government Firewall Protection Profile for Medium Robustness Environments, 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  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.
