Clarify the relationship between FedRAMP as a federal cloud authorization program and NIST SP 800-53 Rev. 5 as the underlying control catalog, addressing the common misconception that NIST 800-53 compliance and FedRAMP authorization are interchangeable.
FedRAMP High, Moderate, and Low baselines compared against the full NIST SP 800-53 Rev. 5 catalog. Applicable to cloud service providers pursuing FedRAMP authorization and federal agencies evaluating cloud service security posture.
FedRAMP is built on NIST SP 800-53 — it uses the same control catalog, control families, and control implementation framework. The relationship is one of subset and specialization: FedRAMP selects specific controls based on baseline impact level, applies FedRAMP-specific parameter values, and adds FedRAMP-specific requirements that do not exist in the base standard.
