The USGCB is a Federal government-wide initiative that provides guidance to agencies on what should be done to improve and maintain an effective configuration settings focusing primarily on security.
The SCAP Security Guide project gives you a head-start with its USGCB profile for Red Hat Enterprise Linux 6. You can use this profile to automatically configure many server settings, so that you can focus on the rules that cannot be automated.
Security Technical Implementation Guides (STIGs) by The United States Department of Defense specify how government computers are to be configured and managed.
