The U.S. Department of Defense has finalized the Cybersecurity Maturity Model Certification (CMMC) rules, mandating contractors to demonstrate compliance with strict cybersecurity standards to qualify for contracts, effective November 9. This initiative aims to bolster the cybersecurity posture of the defense industrial base, requiring contractors to maintain continuous compliance and undergo assessments. The phased rollout over three years is designed to minimize disruption, particularly for smaller entities. This rigorous framework will enhance the protection of sensitive unclassified information, safeguarding national security against potential cyber threats while also reinforcing the integrity of the defense supply chain.
