# PE-6(1) Intrusion Alarms and Surveillance Equipment

> **Enhancement of:** PE-6

## High-Level Description

**Family:** Physical and Environmental Protection (PE)
**Framework:** NIST SP 800-53 Rev 5

Physical intrusion alarms can be employed to alert security personnel when unauthorized access to the facility is attempted. Alarm systems work in conjunction with physical barriers, physical access control systems, and security guards by triggering a response when these other forms of security have been compromised or breached. Physical intrusion alarms can include different types of sensor devices, such as motion sensors, contact sensors, and broken glass sensors. Surveillance equipment includes video cameras installed at strategic locations throughout the facility.

## What to Check

- [ ] Verify PE-6(1) Intrusion Alarms and Surveillance Equipment is documented in SSP
- [ ] Confirm control is operating effectively
- [ ] Review evidence of continuous monitoring for PE-6(1)
- [ ] Verify enhancement builds upon base control PE-6

## How to Test

### Step 1: Review Documentation

Examine the System Security Plan (SSP) and related artifacts for PE-6(1) implementation details. Verify the organization has documented how this control is satisfied.

### Step 2: Validate Implementation

```
# For cloud environments, use cloud-audit-mcp tools
# For on-premises, review system configurations directly

# Example: Check if account management policies exist
grep -r "account.management\|access.control" /etc/security/ 2>/dev/null
```

### Step 3: Test Operating Effectiveness

Verify the control is actively functioning, not just documented. Check logs, configurations, and operational evidence.

## Remediation Guide

### Control Statement

Monitor physical access to the facility where the system resides using physical intrusion alarms and surveillance equipment.
