CM-4(2) Impact Analyses | Verification of Controls
After system changes, verify that the impacted controls are implemented correctly, operating as intended, and producing the desired outcome with regard to meeting the security and privacy requirements for the system.
Source: NIST SP 800-53 Rev 5, CM-4(2). The statement above is our statement of the clause, read from the published text and cited so you can check it against the official text, not the instrument verbatim. Open NIST SP 800-53 Rev 5 in the compliance library.
Base controls and their enhancements. Which apply follows the baseline you are assessed against (for example FedRAMP Moderate or High, or the low, moderate and high baselines of SP 800-53B). Text in square brackets is a parameter your organisation sets.
These are the artefacts auditors commonly ask for on this requirement, our guidance rather than text from the standard. Your assessor decides what is sufficient in your context, and asks for samples across the period when a report covers one.

First move
Common gaps auditors find
- After changes, impacted controls are not re-verified as implemented correctly and operating as intended
- No record identifies which controls a change affected, so post-change control verification cannot be demonstrated
