CMMC Levels
There will be five cumulative Certification levels to the CMMC:
- Level 1 – Basic Cyber Hygiene: Includes basic cybersecurity appropriate for small companies utilizing a subset of universally accepted common practices. The processes at this level would include some performed practices, at least in an ad hoc manner. This level has 35 security controls that must be successfully implemented.
- Level 2 – Intermediate Cyber Hygiene: Includes universally accepted cybersecurity best practices. Practices at this level would be documented, and access to CUI data will require multi-factor authentication. This level includes an additional 115 security controls beyond that of Level 1.
- Level 3 – Good Cyber Hygiene: Includes coverage of all NIST SP 800-171 Rev. 1 controls and additional practices beyond the scope of current CUI protection. Processes at this level are maintained and followed, and there is a comprehensive knowledge of cyber assets. This level requires an additional 91 security controls beyond those covered in Levels 1 and 2.
- Level 4 – Proactive: Includes advanced and sophisticated cybersecurity practices. The processes at this level are periodically reviewed, properly resourced, and are improved regularly across the enterprise. In addition, the defensive responses operate at machine speed and there is a comprehensive knowledge of all cyber assets. This level has an additional 95 controls beyond the first three Levels.
- Level 5 – Advanced / Progressive: Includes highly advanced cybersecurity practices. The processes involved at this level include continuous improvement across the enterprise and defensive responses performed at machine speed. This level requires an additional 34 controls.
CMMC Vs NIST 800-171
It is important that organizations understand that the CMMC will require a CMMC 3rd Party Assessment Organization (C3PAO) to perform an annual independent assessment of their CMMC implementation for the security controls protecting CUI data. This would be in place of NIST 800-171 compliance through self-attestation.
In a recent audit of 10 DoD contractors servicing contracts with a value in excess of $1 million, who self-attested to compliance with NIST SP 800-171, eight were deemed deficient in implementing basic cybersecurity controls. Upon further analysis, it was determined that deficiencies were due to NIST SP 800-171 requiring compliance without regard to strength or maturity of the controls as implemented, and deficiencies in the process of ensuring ongoing, consistent control execution.
Process institutionalization (policies, plans, processes and procedures to manage the environment where the CUI resides) will be a big differentiator in CMMC because it provides assurances that the practices are being implemented effectively and in a sustainable manner.
CMMC Domains will also include four additional controls that are not currently covered under NIST 800-171:
- Asset Management
- Cybersecurity Governance
- Recovery
- Situational Awareness
