Risk Response (03.11.04) Risk Response

High-Level Description

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

Risk Response

What to Check

• Verify Risk Response (03.11.04) Risk Response is implemented for CUI systems
• Review SSP documentation for Risk Response (03.11.04)
• Validate CMMC Level 2 assessment objective for Risk Response (03.11.04)
• Confirm POA&M addresses any gaps for Risk Response (03.11.04)

How to Test

Step 1: Review System Security Plan

Examine the SSP for Risk Response (03.11.04) 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.

Requirement Statement

Implement Risk Response per NIST SP 800-171 Rev 3.

Supplemental Guidance

This requirement addresses the need to determine an appropriate response to risk before generating a plan of action and milestones (POAM) entry. It may be possible to mitigate the risk immediately so that a POAM entry is not needed. However, a POAM entry is generated if the risk response is to mitigate the identified risk and the mitigation cannot be completed immediately.
