NIST SP 800-53 Rev 5 NIST800-CA-2: Control assessments
Requires selection of a suitably independent assessor, a documented assessment plan covering scope, procedures and environment, approval of that plan by the authorizing official before assessment begins, assessment of controls on a defined frequency, and production of an assessment report for defined recipients.

This control maps to 156 controls across 42 other frameworks. If you already hold one of them, the evidence you collected for it is the starting point here rather than new work.
NIST-CSF-ID.IM-02 Improvements are identified from security tests and exercises, including those done in coordination with suppliers and relevant third parties
NIST-CSF-ID.RA-08 Processes for receiving, analyzing, and responding to vulnerability disclosures are established
NIST-CSF-ID.RA-09 The authenticity and integrity of hardware and software are assessed prior to acquisition and use

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-CA-2 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.
