The primary goal of the Cybersecurity Maturity Model Certification is to safeguard what is referred to as Controlled Unclassified Information (CUI) across the DoD supply chain. The DoD’s definition of CUI refers to any information or data created or possessed by the government or another entity on the government’s behalf. The interpretation of data is broad here — and can take into account financial, legal, intelligence, infrastructure, export controls, or other information and data.
The CMMS framework incorporates the processes, practices, and approaches for the purpose of standardizing the assessment of a DoD vendor’s capabilities.
The requirements for CMMC certification, broken into practices and processes, are dependent on the level of certification. Each certification level builds upon the requirements from levels beneath it; for example, a level 3 certification would include requirements for levels 1 and 2.
Here is a brief description of each certification level:
Level 1 demonstrates “Basic Cyber Hygiene” – DoD contractors who wish to pass an audit at this level must implement 17 controls of NIST 800-171 rev1.
Level 2 demonstrates “Intermediate Cyber Hygiene” – Here, DoD contractors must implement another 48 controls of NIST 800-171 rev1 plus seven new “Other” controls.
Level 3 demonstrates “Good Cyber Hygiene” – To achieve level 3 certification, the final 45 controls of NIST 800-171 Rev1 plus 13 new “Other” controls must be implemented
Level 4 demonstrates “Proactive” cybersecurity – In addition to the controls in levels 1 through 3, 11 more controls of NIST 800-171 Rev2 plus 15 new “Other” controls must be implemented
Level 5 demonstrates “Advanced / Progressive” cybersecurity – To achieve this highest level, DoD contractors must implement the final four controls in NIST 800-171 Rev2 plus 11 new “Other” controls
To achieve each certification level, contractors and vendors must meet the requirements for practices and processes associated with that level across 43 different capabilities spanning 17 capability domains.
