What evidence do auditors commonly ask for on SI-4(14) System Monitoring | Wireless Intrusion Detection?

System and information integrity policy; System and information integrity procedures; Procedures addressing system monitoring tools and techniques; System design documentation; System monitoring tools and techniques documentation; System configuration settings and associated documentation.

What is the most common gap auditors find on SI-4(14)?

No wireless intrusion detection deployed, so rogue access points are found only by chance during walk-throughs

NIST SP 800-53 Rev 5 · SI - System and Information Integrity

`SI-4(14)` System Monitoring | Wireless Intrusion Detection

Employ a wireless intrusion detection system to identify rogue wireless devices and to detect attack attempts and potential compromises or breaches to the system.

Source: NIST SP 800-53 Rev 5, SI-4(14). 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

No system holds this evidence for you: it is people and documents. Reminders and routing to the owner still save time. Put the document under version control with an owner and review date, and log each review as a record with reviewer and date.

Common gaps auditors find

No wireless intrusion detection deployed, so rogue access points are found only by chance during walk-throughs
Wireless intrusion detection alerts for rogue devices are logged but never investigated or closed
