FAQ
Who authorizes a federal system?+–
The Authorizing Official (AO) for the agency, based on an assessment, not NIST itself.
How does this relate to FedRAMP?+–
FedRAMP uses 800-53 baselines with a cloud overlay and a JAB or agency authorization path.
Is Moderate enough for CUI?+–
Often yes for many CUI types; some data categories or agencies require additional overlays.
Can commercial SaaS skip 800-53?+–
If they do not serve federal customers, typically yes. FedRAMP or agency ATO is driven by the federal use case.
