DFARS 252.204-7021, known as CMMC on the 10th September 2025, completing the Cybersecurity Maturity Model Certification (CMMC) rulemaking process. CMMC comprises two parts. 32 C.F.R. Part 170 establishes the requirements for the CMMC program. The second part is the final rule, which amends the Defence Federal Acquisition Regulation Supplement (DFARS) and establishes DFARS policies, contract clauses, and other provisions to implement the Program Rule.
The DoD has confirmed in the ruling that it expects the National and International DIB to comply with the ruling. Confirming that the DIB has since 2017 to implementing NIST SP 800-171 and that CMMC is an assurance over the implementation.
The DoD is implementing CMMC through a four-phase process.
Phase 1: Begins on the 10th November, 2025, the effective date of the 48 CRR ruling.
Phase 2: Begins 12 months after Phase 1 Start.
Phase 3: Begins 24 months after Phase 1 Start.
Phase 4 – Full Implementation: Begins 36 months after Phase 1 Start.
The CMMC Program aligns with the DoD’s existing information security requirements for the DIB. It is designed to enforce the protection of sensitive unclassified information shared by the Department with its contractors and subcontractors. The program provides the DoD with increased assurance that contractors and subcontractors are meeting the cybersecurity requirements for non-federal systems processing controlled unclassified information.
A Tiered Model: CMMC requires companies entrusted with sensitive unclassified DoD information to implement cybersecurity standards at progressively advanced levels, depending on the type and sensitivity of the information.
The program also outlines the process for requiring the protection of information flowing down to subcontractors. The tiering comprises 3 levels of compliance: Level 1, Level 2 and Level 3.
Level 1: Basic Safeguarding of Federal Contract Information (FCI)
Level 2: Broad Protection of Controlled Unclassified Information (CUI).
Level 3: Higher-Level Protection of CUI Against Advanced Persistent Threats.
CMMC Level Requirements: DoD requirements for the three CMMC levels. Level 1, Level 2 and Level 3.
