AC-2(4) Automated Audit Actions

Enhancement of: AC-2

High-Level Description

Family: Access Control (AC) Framework: NIST SP 800-53 Rev 5

Account management audit records are defined in accordance with AU-02 and reviewed, analyzed, and reported in accordance with AU-06.

What to Check

Verify AC-2(4) Automated Audit Actions is documented in SSP
Confirm control is operating effectively
Review evidence of continuous monitoring for AC-2(4)
Verify enhancement builds upon base control AC-2

How to Test

Step 1: Review Documentation

Examine the System Security Plan (SSP) and related artifacts for AC-2(4) 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.
