Decoding DoD cybersecurity: Compliance guide for DIB organizations

This article provides a compliance guide for Defense Industrial Base (DIB) organizations navigating DoD cybersecurity requirements including CMMC, DFARS, and FedRAMP.

• Compliance obligations vary by role: prime contractors, subcontractors, MSPs/MSSPs, and cloud service providers face different CMMC levels and assessment methods based on data sensitivity
• Point-in-time compliance is insufficient; continuous monitoring, real-time visibility, and automated evidence collection are now required
• Seven-step roadmap: know your data, define boundaries, assess current state, build documentation, validate cloud services, engage supply chain, and invest in continuous monitoring
• MSPs and MSSPs handling CUI need CMMC Level 2 certification; those handling only security protection data fall within client assessments
• AWS GovCloud (US) provides isolation and controls supporting continuous compliance capabilities for defense workloads
• Mandatory third-party assessments were suspended pending review but expected to return with full implementation targeted by 2028

Organizations treating compliance as a security transformation rather than a checkbox exercise will maintain contract eligibility and strengthen their position in the defense supply chain.
