48 FAR 52.204-21
What is 48 FAR 52.204-21?
Finalized and approved in June 2016, the 48 FAR 52.204-21 Federal Acquisition Regulation (FAR) requires all Federal Contractors to improve their Basic Safeguarding of Covered Contractor Information Systems. It defines that federal contractors must be compliant with the below fifteen cybersecurity and physical security controls. These are a very basic subset of the NIST Special Publication 800-171 controls for safeguarding Controlled Unclassified Information (CUI) and/or Covered Defense Information (CDI) that defense contractors must follow.
48 FAR 52.204-21 is a set of security requirements that have been added to federal contracts beginning in June 2016. It defines uniform policies and practices across the federal government and throughout all Prime and Sub Contractor companies conducting business with the US Federal Government. The fifteen safeguarding requirements and procedures are as shown below:
