Level 2 requires that an organization establish and document practices and policies to guide the
implementation of their CMMC efforts. The documentation of practices enables individuals to perform
them in a repeatable manner. Organizations develop mature capabilities by documenting their
processes and then practicing them as documented.
As an intermediate cyber hygiene level, level 2 serves as a progression from Level 1 to Level 3 and consists
of a subset of the security requirements specified in NIST SP 800-171  as well as practices from
other standards and references. Because this level represents a transitional stage, a subset of the
practices reference the protection of CUI.
The CMMC model consists of 17 domains. The majority of these domains originate from the security-related
areas in Federal Information Processing Standards (FIPS) Publication 200  and the related security
requirement families from NIST SP 800-171 . Level 2 consist of the following CMMC domains.
