In this post we explain CMMC Level 1 requirements.

CMMC has five maturity levels. Level 1 is the lowest level. Level 1 CMMC requirements seek to ensure that a contractor can “safeguard federal contract information”. This is achieved by requiring contractors to practice “Basic Cyber Hygiene”. It is expected that most DoD contractors will only need to earn a level 1 CMMC certification.

Who does CMMC Level 1 Apply to?

CMMC applies to U.S. Department of Defense contractors who store, process or transmit Federal contract information (FCI). Every company required to earn a CMMC certification will need to implement the practices associated with CMMC level 1.

CMMC Level 1 Practices

There are seventeen practices associated with CMMC level 1. An organization with a level 1 CMMC requirement is required to perform all 17 practices. The CMMC practices for level 1 were drawn from the security controls in FAR 52.204-21.
