CMMC Details
What It Is
Cybersecurity Maturity Model Certification (CMMC) 2.0 is a DoD certification program verifying cybersecurity protections for Federal Contract Information (FCI) and Controlled Unclassified Information (CUI) in the Defense Industrial Base (DIB). It uses a tiered model with three levels, drawing from FAR 52.204-21, NIST SP 800-171 Rev 2, and NIST SP 800-172, emphasizing verified implementation over self-attestation.
Key Components
- **Three cumulative levelsLevel 1 (15 FAR practices), Level 2 (110 NIST 800-171 controls across 14 domains), Level 3 (+24 NIST 800-172 enhancements).
- Assessment via self, C3PAO, or DIBCAC; SPRS/eMASS reporting.
- POA&Ms with 180-day limits; enclave scoping for targeted compliance.
Why Organizations Use It
Mandated for DoD contracts, ensuring eligibility; reduces breach risks, enhances supply chain trust; provides competitive edge in bids and primes' preferences; builds operational resilience.
Implementation Overview
Phased approach: scoping, gap analysis, remediation, assessment preparation, certification, sustainment. Targets DIB contractors/subcontractors; complex for SMEs, requires cross-functional teams, C3PAO audits for Level 2+.
