# Unified Federal Information Security Framework
**Entity class:** Interagency security-framework initiative
## Definition
The **Unified Federal Information Security Framework** was the NIST, DoD, Intelligence Community, and CNSS effort announced on June 16, 2009 to give civilian, defense, and intelligence systems a common federal information-security foundation. Its first installment was NIST SP 800-53 Revision 3 and its common catalog of security controls.
The framework unified the control and risk-management grammar while allowing national-security systems and agencies to impose tailored baselines, overlays, parameters, and implementation requirements.
