DFARSDefense Federal Acquisition Regulation Supplement

The Defense Federal Acquisition Regulation Supplement (DFARS) contains Department of Defense (DOD) regulations that supplement the Federal Acquisition Regulation (FAR). DFARS implements and supplements FAR policies and procedures for DOD acquisitions and provides additional requirements specific to defense contracting. Key areas addressed include cybersecurity requirements (DFARS 252.204-7012), cost accounting standards, foreign acquisition restrictions, and unique DOD contract clauses. Contractors working on DOD contracts must comply with both FAR and DFARS requirements. DFARS clauses are typically identified by numbering in the 252.XXX range. Understanding DFARS is critical for defense contractors as non-compliance can result in contract termination, False Claims Act liability, or debarment.
