Everything defense contractors need to know about DFARS cybersecurity requirements, incident reporting, and how DFARS connects to CMMC.
Check DFARS Compliance →DFARS 252.204-7012 ("Safeguarding Covered Defense Information and Cyber Incident Reporting") is the Defense Federal Acquisition Regulation Supplement clause that requires defense contractors to:
DFARS 252.204-7012 has been the primary cybersecurity requirement for DoD contracts since 2017. CMMC adds a verification layer — while DFARS required self-attestation, CMMC requires third-party certification for most Level 2 contracts.
A new DFARS clause — 252.204-7021 — specifies the required CMMC level for each contract. Both clauses will coexist, meaning you need to comply with both DFARS 7012 (controls + reporting) and DFARS 7021 (certification).
Implement NIST 800-171 controls on all systems processing, storing, or transmitting CUI. This is the same 110 controls required for CMMC Level 2.
Report cyber incidents affecting CUI to DoD within 72 hours via the DIBNet portal. Include malware samples, forensic images, and system logs.
Include DFARS 7012 in all subcontracts where subcontractors will handle CUI. You're responsible for your supply chain's compliance.
Preserve images of affected systems and all relevant monitoring data for at least 90 days following a reported incident.
