- Use the monitoring the facility actually has — badge-system alerts, cameras, alarms, or human presence in small facilities — and define what reviewing its output means in practice.
- Fold physical anomalies into the incident process under 03.06.01: a propped server-room door is an incident, not a facilities quirk.
03.10.02 — Monitoring Physical Access
03.10 Physical Protection · NIST SP 800-171 Rev. 3
Requires monitoring physical access to the facility where the system resides to detect and respond to physical security incidents, and reviewing physical access logs at an organization-defined frequency and upon occurrence of organization-defined events or potential indications of events.
Rev. 3 requirement text is multi-part and parameterized with organization-defined values, so this site summarizes rather than reproduces it. The summary is independent — read the official publication for the binding wording.
NIST SP 800-171 Rev. 3 — Protecting CUI in Nonfederal Systems ↗NIST SP 800-171A Rev. 3 — Assessing Security Requirements for CUI ↗What this requirement is after
Somebody has to be able to notice the forced door, the badge used at 3 a.m., or the tailgater on camera — and the logs have to be looked at on a schedule, not only after something is already known to be wrong.
Carries Rev. 2's protect-and-monitor requirement forward with log review made explicit — a defined frequency plus event-driven review.
Brilliant at the Basics practices that support this requirement
The campaign’s twenty practices are a priority list, not a control catalog, and none of them works this requirement’s substance directly. It still applies to you if it is in your contract’s scope: address it through your own implementation and the related artifacts below, and treat the absence of a mapping here as honesty, not permission to skip it.
Implementation considerations and evidence
- Physical access log reviews at the defined frequency
- Alarm or camera coverage documentation for the relevant areas
