SI-2(4) Flaw Remediation | Automated Patch Management Tools

Employ automated patch management tools to facilitate flaw remediation to the following system components: organization-defined system components.

Source: NIST SP 800-53 Rev 5, SI-2(4). 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.

where the evidence lives
teal = a system already holds it · olive = produced at each review. To go live: easy when half or more of the artefacts are already held by a system, moderate from a quarter to a half, hard below a quarter.

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

Mostly documents and reviews. Pull the 1 system-held artefact from your Vulnerability scanner / patch tooling on a schedule; put the documents under version control with an owner and review date, and log each review as a dated record with a named reviewer.
