This control maps to 27 controls across 15 other frameworks. If you already hold one of them, the evidence you collected for it is the starting point here rather than new work.

Other controls in IA - Identification and Authentication

You are reading one control. How much of NIST SP 800-53 Rev 5 have you already done?

NIST SP 800-53 Rev 5 NIST800-IA-9 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 1014 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.
