cyberstrikeus PE-23 Facility Location
High-Level Description
Family: Physical and Environmental Protection (PE) Framework: NIST SP 800-53 Rev 5
Physical and environmental hazards include floods, fires, tornadoes, earthquakes, hurricanes, terrorism, vandalism, an electromagnetic pulse, electrical interference, and other forms of incoming electromagnetic radiation. The location of system components within the facility is addressed in PE-18.
What to Check
- Verify PE-23 Facility Location is documented in SSP
- Validate all 2 control requirements are implemented
- Confirm control is operating effectively
- Review evidence of continuous monitoring for PE-23
How to Test
Step 1: Review Documentation
Examine the System Security Plan (SSP) and related artifacts for PE-23 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.

Control Statement
Plan the location or site of the facility where the system resides considering physical and environmental hazards; and For existing facilities, consider the physical and environmental hazards in the organizational risk management strategy.
Implementation Guidance
Physical and environmental hazards include floods, fires, tornadoes, earthquakes, hurricanes, terrorism, vandalism, an electromagnetic pulse, electrical interference, and other forms of incoming electromagnetic radiation. The location of system components within the facility is addressed in PE-18.
