Defense Federal Acquisition Regulation Supplement
Defense and government contractors operating under the Defense Federal Acquisition Regulation Supplement face a compliance environment driven primarily by the U.S. Department of Defense and administered through the Defense Acquisition Regulations System, with the Office of the Under Secretary of Defense for Acquisition and Sustainment setting the pace on cybersecurity, supply chain, and cost accounting requirements. The Cybersecurity Maturity Model Certification 2.0 rulemaking has pushed compliance teams to reassess how they document third-party vendor controls and self-attestation eligibility before contract award. Contractors in scope are actively mapping flow-down clauses in subcontractor agreements against updated DFARS 252.204-7021 requirements.
Watch
- DFARS 252.204-7021: CMMC flow-down obligations to subcontractors at all tiers
- CMMC 2.0 final rule implementation timeline and third-party assessment triggers
- Proposed DFARS amendments on domestic sourcing under the specialty metals restriction
- DoD class deviations issued outside the standard rulemaking cycle
- Foreign ownership, control, or influence disclosure requirements under active revision
