**NIST SP 800-53 Rev. 5**·Control `PE-6(1)`·high·Component: **Physical and Environmental Protection**

## What this control requires

> The control requires using physical intrusion alarms and surveillance equipment to monitor physical access to the facility where the system resides. These alarms alert security personnel to unauthorized access attempts, and surveillance equipment, such as video cameras and motion sensors, provides real-time monitoring and alerts for potential breaches. This control supports the Intrusion Detection and Surveillance Systems capability within the Physical and Environmental Protection family.

### In plain English

The control requires using physical intrusion alarms and surveillance equipment to monitor physical access to the facility where the system resides. In practice, this means you can prove you access management-level controls on a defined cadence.

## Why it matters

SP 800-53 is the catalogue every U.S. federal authorisation (FedRAMP, FISMA, CMMC) and most regulated industries point at. A missing control surfaces as a Plan of Action & Milestones (POA&M) item that an Authorizing Official must approve before the Authority To Operate is granted or renewed.

This control is rated **high**. Auditors expect a named owner, a remediation SLA, and a tooling artefact that evidences continuous operation.

## What an auditor looks for

A 3PAO (FedRAMP) or Independent Assessor (NIST RMF) tests against NIST SP 800-53A assessment procedures. For each control they expect a documented implementation that addresses every assessment objective (Examine, Interview, Test) and an implementation summary in the System Security Plan.

Within **Physical and Environmental Protection**, the assessor will trace your implementation back to the catalogue reference (Control PE-6(1)) and look for objective evidence on the latest two assessment cycles.

## How to implement

#### Physical Security

**Inheritance.** For cloud-only operations, inherit physical controls from the provider's SOC 2 / ISO 27001 report and document the inheritance in the SoA.

### Operational checklist

-   **Access.** Document the trigger, the owner and the cadence.
-   **Security.** Document the trigger, the owner and the cadence.
-   **Detection.** Document the trigger, the owner and the cadence.
-   **Physical.** Document the trigger, the owner and the cadence.
-   **Review.** Document the trigger, the owner and the cadence.
-   **Scope:** management, system, personnel, time, alerts, protection, identity, monitor.

## Evidence to collect

-   **Identity Scan.** IAM / IdP exports — Entra ID, Okta, IAM Identity Center, Workspace directory — showing accounts, roles, MFA state and last sign-in.

Identity analytics (Okta, SailPoint, Access Analyzer) demonstrates least-privilege. Focus: Intrusion Alarms And Surveillance Equipment.

## How it maps to other frameworks

Computed from shared tags, control component and key-operation subjects — handy when you are reconciling controls across an audit.
