PE-9 Power Equipment and Cabling

High-Level Description

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

Organizations determine the types of protection necessary for the power equipment and cabling employed at different locations that are both internal and external to organizational facilities and environments of operation. Types of power equipment and cabling include internal cabling and uninterruptable power sources in offices or data centers, generators and power cabling outside of buildings, and power sources for self-contained components such as satellites, vehicles, and other deployable systems.

What to Check

• Verify PE-9 Power Equipment and Cabling is documented in SSP
• Confirm control is operating effectively
• Review evidence of continuous monitoring for PE-9

How to Test

Step 1: Review Documentation

Examine the System Security Plan (SSP) and related artifacts for PE-9 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

Protect power equipment and power cabling for the system from damage and destruction.

Implementation Guidance
