PE-19 Information Leakage

High-Level Description

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

Information leakage is the intentional or unintentional release of data or information to an untrusted environment from electromagnetic signals emanations. The security categories or classifications of systems (with respect to confidentiality), organizational security policies, and risk tolerance guide the selection of controls employed to protect systems against information leakage due to electromagnetic signals emanations.

What to Check

• Verify PE-19 Information Leakage is documented in SSP
• Confirm control is operating effectively
• Review evidence of continuous monitoring for PE-19

How to Test

Step 1: Review Documentation

Examine the System Security Plan (SSP) and related artifacts for PE-19 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.
