Why NIST 800-53 Rev. 5 Compliance Matters
NIST 800-53 Rev. 5 is the authoritative framework for securing federal information systems and protecting privacy. It is required for FISMA compliance, foundational to FedRAMP authorization, and often referenced in industry frameworks for risk-based security programs. The updated Rev. 5 expands focus areas for privacy, supply chain, and system resilience—requiring holistic review and alignment.
