Understanding CMMC Regulations
What is CMMC?
CMMC goes beyond traditional compliance models by requiring third-party assessments & certifications. This approach ensures that contractors not only implement required security controls but also demonstrate their effectiveness in practice.
The Evolution of CMMC
To fully grasp the significance of CMMC regulations, it’s essential to understand their evolution:
- Pre-CMMC Era: Before CMMC, defense contractors relied on self-attestation to certify their compliance with cybersecurity standards outlined in the Defense Federal Acquisition Regulation Supplement [DFARS]. This approach, while less burdensome, left significant gaps in cybersecurity implementation across the DIB.
- CMMC 1.0: Introduced in 2020, this version established five certification levels, each with its own set of practices & processes. It represented a significant shift towards a more rigorous & verifiable cybersecurity framework.
- CMMC 2.0: Launched in November 2021, this streamlined version reduced the model to three levels, aiming to decrease costs & improve implementation. CMMC 2.0 also introduced the concept of Plan of Action & Milestones [POA&M] for certain requirements, allowing contractors to address some gaps over time.
The Three Levels of CMMC 2.0
- Level 1 (Foundational):
- Requires annual self-assessment
- Level 2 (Advanced):
- Aims to protect Controlled Unclassified Information [CUI]
- Requires third-party assessment for critical national security information
- Encompasses 110 practices aligned with NIST SP 800-171
- Level 3 (Expert):
- Designed to protect CUI & reduce the risk of Advanced Persistent Threats [APTs]
- Requires government-led assessments
- Includes additional practices beyond NIST SP 800-171
