CMMC 2.0: The Clock Is Ticking for Defense Contractors
The Cybersecurity Maturity Model Certification (CMMC) 2.0 is no longer a future concern -- it is here. Phase 1 started in November 2025, and by October 31, 2026, all new Department of Defense contracts will require CMMC certification. Phase 2 begins on November 10, 2026, expanding Level 2 requirements even further.
This affects approximately 300,000 defense contractors across the United States who handle Controlled Unclassified Information (CUI). If your organization is part of the defense industrial base, compliance is not optional -- it is a prerequisite for doing business with the DoD.
What NIST SP 800-171 Requires for Document Management
At the core of CMMC Level 2 lies NIST SP 800-171, which includes 110 security practices. The document management requirements are extensive:
- Access control -- limit CUI access to authorized users only, with role-based permissions
- Audit and accountability -- maintain detailed logs of who accesses, modifies, or transmits CUI documents
- Media protection -- encrypt CUI at rest and in transit; sanitize media before disposal
- System and communications protection -- encrypt communications carrying CUI; segment networks
- Identification and authentication -- multi-factor authentication for all CUI access
CUI Handling: Common Mistakes That Fail Assessments
Many contractors underestimate the documentation requirements. Common failures include:
- Storing CUI in unencrypted cloud storage or personal drives
- Lacking audit trails that show document access history
- No formal retention and destruction policies for CUI documents
- Using consumer-grade file sharing tools (Dropbox, Google Drive) without FedRAMP authorization
- Failing to maintain a System Security Plan (SSP) and Plan of Action and Milestones (POA&M)
Key CMMC Deadlines
| Date | Milestone |
|---|---|
| November 2025 | CMMC Phase 1 begins |
| October 31, 2026 | Phase 1 full implementation -- all new contracts require CMMC |
| November 10, 2026 | Phase 2 begins -- broader Level 2 requirements |
