CMMC (Cybersecurity Maturity Model Certification), developed by the Department of Defense (DoD), reinforces cybersecurity for organizations handling sensitive defense information. This level builds upon NIST SP 800-171 controls, including access control and incident response. It safeguards Controlled Unclassified Information (CUI), reflecting a moderate level of cybersecurity readiness. CMMC certification is required for DoD contractors, providing supply chain assurance and minimizing the impact of potential cybersecurity incidents. Cybersecurity readiness is crucial for defense contractors because they work with sensitive information and technology that can be used to harm national security if it falls into the wrong hands.
