IR-6(2)_vulnerabilities-related-to-incidents

IR-6(2) Vulnerabilities Related to Incidents

Enhancement of: IR-6

High-Level Description

Family: Incident Response (IR) Framework: NIST SP 800-53 Rev 5

Reported incidents that uncover system vulnerabilities are analyzed by organizational personnel including system owners, mission and business owners, senior agency information security officers, senior agency officials for privacy, authorizing officials, and the risk executive (function). The analysis can serve to prioritize and initiate mitigation actions to address the discovered system vulnerability.

What to Check

• Verify IR-6(2) Vulnerabilities Related to Incidents is documented in SSP
• Confirm control is operating effectively
• Review evidence of continuous monitoring for IR-6(2)
• Verify enhancement builds upon base control IR-6

How to Test

Step 1: Review Documentation

Examine the System Security Plan (SSP) and related artifacts for IR-6(2) 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.
