Incident Response Testing (03.06.03) Incident Response Testing

High-Level Description

Family: Incident Response Framework: NIST SP 800-171 Rev 3 Applicability: Systems processing, storing, or transmitting CUI

Incident Response Testing

What to Check

• Verify Incident Response Testing (03.06.03) Incident Response Testing is implemented for CUI systems
• Review SSP documentation for Incident Response Testing (03.06.03)
• Validate CMMC Level 2 assessment objective for Incident Response Testing (03.06.03)
• Confirm POA&M addresses any gaps for Incident Response Testing (03.06.03)

How to Test

Step 1: Review System Security Plan

Examine the SSP for Incident Response Testing (03.06.03) implementation description and responsible parties.

Step 2: Assess Implementation

# Verify security controls protecting CUI
# Check access controls, encryption, monitoring as applicable

# For Linux systems:
ls -la /etc/security/ 2>/dev/null
grep -r "CUI\|controlled" /etc/security/ 2>/dev/null

# For cloud:
# Use cloud-audit-mcp tools to assess posture

Step 3: CMMC Assessment Validation

Verify this requirement passes CMMC Level 2 assessment methodology per SP 800-171A Rev 3.

Tools

Remediation Guide

Requirement Statement

Implement Incident Response Testing per NIST SP 800-171 Rev 3.

Supplemental Guidance

Organizations test incident response capabilities to determine their effectiveness and identify potential weaknesses or deficiencies. Incident response testing includes the use of checklists, walk-through or tabletop exercises, and simulations. Incident response testing can include a determination of the effects of incident response on organizational operations, organizational assets, and individuals. Qualitative and quantitative data can help determine the effectiveness of incident response processes.
