As cybersecurity threats evolve, the U.S. Department of Defense (DoD) has introduced a long-awaited pivotal framework aimed at bolstering the security of its national defense supply chain: The Cybersecurity Maturity Model Certification (CMMC) Program. The new rule, published Oct. 15, 2024, marks a significant step toward enhancing cybersecurity across the Defense Industrial Base (DIB). The final rule aligns closely with existing National Institute of Standards and Technology (NIST) guidelines, specifically NIST SP 800-171 R2 and selected NIST SP 800-172 requirements. 

This article explains how the DoD’s new program sets stringent compliance standards to protect sensitive data across the defense supply chain, enhancing national security.
