PE-2(3) Restrict Unescorted Access

Enhancement of: PE-2

High-Level Description

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

Individuals without required security clearances, access approvals, or need to know are escorted by individuals with appropriate physical access authorizations to ensure that information is not exposed or otherwise compromised.

What to Check

• Verify PE-2(3) Restrict Unescorted Access is documented in SSP
• Confirm control is operating effectively
• Review evidence of continuous monitoring for PE-2(3)
• Verify enhancement builds upon base control PE-2

How to Test

Step 1: Review Documentation

Examine the System Security Plan (SSP) and related artifacts for PE-2(3) 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.
