SI-4(14) Wireless Intrusion Detection

Enhancement of: SI-4

High-Level Description

Family: System and Information Integrity (SI) Framework: NIST SP 800-53 Rev 5

Wireless signals may radiate beyond organizational facilities. Organizations proactively search for unauthorized wireless connections, including the conduct of thorough scans for unauthorized wireless access points. Wireless scans are not limited to those areas within facilities containing systems but also include areas outside of facilities to verify that unauthorized wireless access points are not connected to organizational systems.

What to Check

Verify SI-4(14) Wireless Intrusion Detection is documented in SSP
Confirm control is operating effectively
Review evidence of continuous monitoring for SI-4(14)
Verify enhancement builds upon base control SI-4

How to Test

Step 1: Review Documentation

Examine the System Security Plan (SSP) and related artifacts for SI-4(14) 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.
