PE-6 Monitoring Physical Access

High-Level Description

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

Physical access monitoring includes publicly accessible areas within organizational facilities. Examples of physical access monitoring include the employment of guards, video surveillance equipment (i.e., cameras), and sensor devices. Reviewing physical access logs can help identify suspicious activity, anomalous events, or potential threats. The reviews can be supported by audit logging controls, such as AU-2 , if the access logs are part of an automated system. Organizational incident response capabilities include investigations of physical security incidents and responses to the incidents. Incidents include security violations or suspicious physical access activities. Suspicious physical access activities include accesses outside of normal work hours, repeated accesses to areas not normally accessed, accesses for unusual lengths of time, and out-of-sequence accesses.

What to Check

• Verify PE-6 Monitoring Physical Access is documented in SSP
• Validate all 3 control requirements are implemented
• Confirm control is operating effectively
• Review evidence of continuous monitoring for PE-6

How to Test

Step 1: Review Documentation

Examine the System Security Plan (SSP) and related artifacts for PE-6 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.
