CMMC Level 3

Information technology explained.

What is CMMC Level 3?

The Cybersecurity Maturity Model Certification ('CMMC') is a standard model for cybersecurity implementation across the Defense Industrial Base ('DIB'). The CMMC model is designed to provide increased assurance to the Department of Defense (DoD) that a DIB company has adequate protection in place to protect sensitive unclassified information.

There are five levels of CMMC. CMMC Level 3 includes the 110 security requirement specifications from NIST SP 800-171. The CMMC Model also incorporates standards from NIST SP 800-53.

CMMC Level 3 specifically requires that DIB organizations "establish, maintain, and resource a plan demonstrating the management of activities for practice implementation.
