CMMC (Cybersecurity Maturity Model Certification) is a Department of Defense framework requiring defense contractors to implement and certify cybersecurity practices. It builds on NIST SP 800-171 requirements and establishes three maturity levels for protecting Controlled Unclassified Information (CUI) and Federal Contract Information (FCI).

What is the difference between CMMC Level 1, Level 2, and Level 3?

CMMC Level 1 (Foundational) requires 17 basic cyber hygiene practices and allows self-assessment. Level 2 (Advanced) requires all 110 NIST SP 800-171 controls and third-party assessment by a C3PAO for most contractors. Level 3 (Expert) adds additional controls from NIST SP 800-172 and requires government-led assessments for the most sensitive programs.

What is NIST SP 800-171?

NIST Special Publication 800-171 provides security requirements for protecting Controlled Unclassified Information (CUI) in non-federal systems. It contains 110 security controls across 14 families including Access Control, Audit and Accountability, Configuration Management, and Incident Response. CMMC Level 2 is based on these requirements.

A C3PAO (CMMC Third-Party Assessment Organization) is an organization authorized by the Cyber AB to conduct CMMC Level 2 assessments. C3PAOs employ certified CMMC assessors who evaluate whether defense contractors meet the required security controls before they can be awarded contracts requiring CMMC certification.

CMMC Watch regenerates automatically every day at 6 AM EST via GitHub Actions, aggregating the latest CMMC and compliance news from government, defense industry, and Reddit sources. The site uses AI to curate and categorize the most relevant stories for defense contractors.

What sources does CMMC Watch aggregate?

We aggregate from major federal and defense news sources including FedScoop, DefenseScoop, Federal News Network, Nextgov, Breaking Defense, Defense One, Defense News, ExecutiveGov, SecurityWeek, Cyberscoop, and GovCon Wire. We also monitor Reddit communities like r/CMMC, r/NISTControls, r/FederalEmployees, and r/GovContracting.

When does CMMC go into effect?

The CMMC 2.0 final rule was published in October 2024 and became effective December 16, 2024. DoD is implementing CMMC requirements in a phased approach, with requirements appearing in new contracts starting in 2025. Check CMMC Watch daily for the latest implementation timeline updates.

What is the Defense Industrial Base (DIB)?

The Defense Industrial Base (DIB) comprises over 300,000 companies that provide products and services to the Department of Defense. These contractors must protect sensitive government information through cybersecurity frameworks like CMMC. CMMC Watch covers news relevant to all DIB organizations.
