What is Cybersecurity Maturity Model Certification CMMC?

Understanding Cybersecurity Maturity Model Certification CMMC

Cybersecurity Maturity Model Certification (CMMC) represents the Department of Defense's effort to ensure that defense contractors adequately protect sensitive information by requiring third-party certification of their security practices. Unlike self-attestation models that proved inadequate, CMMC requires organizations to demonstrate actual implementation of security controls appropriate to the sensitivity of information they handle. The model defines five progressive maturity levels, from basic cyber hygiene to advanced/progressive practices, with specific practices and processes required at each level. Defense contractors must achieve certification at the appropriate level before bidding on contracts that handle controlled unclassified information. The certification process involves assessment by authorized third-party assessment organizations, with certifications valid for three years. What makes CMMC particularly challenging is that it requires not just implementing controls, but demonstrating institutionalization of cybersecurity processes. Organizations preparing for certification typically invest in significant security improvements, documentation of practices, and readiness assessments to identify and address gaps before formal evaluation.
