The Cybersecurity Maturity Model Certification (CMMC) framework is a key requirement for defense contractors working with the Department of Defense (DoD). It establishes a set of security standards to protect Controlled Unclassified Information (CUI) and Federal Contract Information (FCI). In 2021, the DoD introduced CMMC 2.0, an updated version designed to simplify compliance requirements while maintaining strong cybersecurity protections.

Key Differences Between CMMC 1.0 and CMMC 2.0

1. Reduced Number of Certification Levels

CMMC 2.0 streamlines the compliance process by reducing the number of levels from five to three:

  • Level 1 (Foundational): Basic cybersecurity requirements for companies handling FCI.
  • Level 2 (Advanced): Strict security controls for companies managing CUI, aligned with NIST SP 800-171.
  • Level 3 (Expert): The highest level, designed for contractors working on the DoD’s most sensitive projects, incorporating NIST SP 800-172 controls.

2. Alignment with NIST Standards

The new CMMC 2.0 Level 2 certification is now fully aligned with NIST SP 800-171, consisting of 110 security controls. This eliminates the 20 extra security requirements from the previous CMMC 1.0 Level 3, simplifying compliance while maintaining stringent protections.

3. Introduction of POAMs (Plans of Action and Milestones)

Unlike CMMC 1.0, which required full compliance at the time of assessment, CMMC 2.0 allows limited use of POAMs to address non-critical security gaps. This gives organizations additional time to close minor security deficiencies, provided they submit an acceptable plan for remediation.

4. Certification Waivers

In select, limited circumstances, waivers may be granted for certification requirements. These will be approved at the DoD’s discretion and are expected to be rare.

5. Self-Assessments for Certain Levels

CMMC 2.0 introduces self-assessments for certain contractors, reducing the burden of third-party audits:

  • Level 1 contractors can now self-certify their compliance annually.
  • Level 2 contractors that do not handle sensitive CUI can also self-certify.
  • Level 2 contractors handling critical CUI and Level 3 contractors will still require a third-party assessment conducted by a certified CMMC Third-Party Assessment Organization (C3PAO).

Breakdown of CMMC 2.0 Levels

Level 1 (Foundational)

  • Applies to companies handling Federal Contract Information (FCI).
  • Based on FAR 52.204-21, which includes 17 basic cybersecurity controls.
  • Requires annual self-assessments and affirmation by a senior company official.

Level 2 (Advanced)

  • Applies to companies that handle Controlled Unclassified Information (CUI).
  • Fully aligned with NIST SP 800-171 (110 security controls).
  • Divided into two categories:
    • Critical CUI handlers require a third-party assessment by a C3PAO every three years.
    • Non-critical CUI handlers may self-certify compliance annually.

Level 3 (Expert)

  • Designed for contractors working on the DoD’s most sensitive projects.
  • Builds on NIST SP 800-171 (110 controls) and incorporates a subset of NIST SP 800-172 controls to protect against Advanced Persistent Threats (APTs).
  • Assessments will be conducted by the DoD itself rather than C3PAOs.

Why CMMC 2.0 Matters for DoD Contractors

CMMC 2.0 is a significant update that ensures strong cybersecurity protections while reducing unnecessary burdens for defense contractors. The DoD has made it clear that while CMMC 2.0 is still undergoing final rulemaking, enforcement of existing NIST SP 800-171 requirements is already in place. Contractors that fail to meet these standards risk losing DoD contracts.

Next Steps for DoD Contractors

  1. Determine your required CMMC level based on the type of data your organization handles.
  2. Conduct a gap analysis against NIST SP 800-171 and FAR 52.204-21 controls.
  3. Prepare for third-party assessments if required (for Level 2 critical CUI and Level 3 contractors).
  4. Implement POAMs where applicable, ensuring compliance with non-critical controls.
  5. Stay updated on rulemaking progress to ensure compliance with evolving regulations.
