As the cyber threat landscape becomes increasingly dominated by state-sponsored actors and advanced persistent threats, the DoD has taken critical steps to evolve its cybersecurity requirements for defense contractors.
For contractors handling Controlled Unclassified Information and seeking to achieve CMMC Level 3, the NIST SP 800-172 Enhanced Security Requirements represent the most stringent technical and procedural benchmarks currently required in the DIB.
This article explores the practical implementation of NIST 800-172 controls, emphasizing advanced security capabilities, resilience engineering, and operational maturity necessary for high-trust environments.
