Requires authenticators to be managed end to end: identity verified before issue, initial content set, strength appropriate to use, administrative procedures for distribution, loss, compromise and revocation, default authenticators changed, minimum and maximum lifetimes with reuse conditions enforced, authenticators changed on a defined frequency by type, content protected, and protection requirements implemented by users and devices.
NIST SP 800-53 Rev 5 NIST800-IA-5 is one control. If you already hold one of the frameworks below, a reviewed crosswalk already says how much of NIST SP 800-53 Rev 5 your existing evidence covers. Hold ISO 27001:2022 and 163 of 300 NIST SP 800-53 Rev 5 controls already carry evidence.
Each report names every control your existing framework evidences, every one it does not, the reasoning behind each claim, and the claims that were argued against and rejected. 342 were rejected on the ISO 27001:2022 pair alone.
The graph holds this control, the 0 it maps to, and the evidence behind each claim, over MCP and REST.
