NIST IR 8587: requirements, implementation, and the gap after token validation
NIST IR 8587 explains how federal agencies and their cloud providers should protect signed identity tokens, access tokens, and assertions from forgery, theft, and misuse. This implementation guide maps the report's architecture, signing-key protection, token verification, lifecycle, revocation, session monitoring, and logging guidance to practical work. It also distinguishes the report's voluntary conformance model, MUST requirements, and SHOULD recommendations. MagenTrust is presented only as a complementary runtime control: token validation proves that the credential is valid, while point-of-action continuous identity assurance tests who or what is exercising its authority now. MagenTrust does not replace identity providers, authorization servers, MFA, token hardening, revocation, or any IR 8587 control.
