DFARS (Defense Federal Acquisition Regulation Supplement)

The Defense Federal Acquisition Regulation Supplement (DFARS) provides additional procurement rules and procedures specific to the Department of Defense (DoD). It supplements the FAR with defense-unique policies and implements statutory requirements specific to defense acquisition.

DFARS covers critical areas including cybersecurity requirements (DFARS 252.204-7012 for NIST SP 800-171 compliance), foreign ownership restrictions, cost accounting standards, and specialty metals requirements. The cybersecurity clause alone has significant implications, requiring contractors to implement 110 security controls to protect Controlled Unclassified Information (CUI).

Companies pursuing DoD contracts must understand both FAR and DFARS requirements. Non-compliance with DFARS clauses can result in contract termination, False Claims Act liability, and suspension or debarment from future contracts.
