IR-4(10)_supply-chain-coordination

IR-4(10) Supply Chain Coordination

Enhancement of: IR-4

High-Level Description

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

Organizations involved in supply chain activities include product developers, system integrators, manufacturers, packagers, assemblers, distributors, vendors, and resellers. Supply chain incidents can occur anywhere through or to the supply chain and include compromises or breaches that involve primary or sub-tier providers, information technology products, system components, development processes or personnel, and distribution processes or warehousing facilities. Organizations consider including processes for protecting and sharing incident information in information exchange agreements and their obligations for reporting incidents to government oversight bodies (e.g., Federal Acquisition Security Council).

What to Check

• Verify IR-4(10) Supply Chain Coordination is documented in SSP
• Confirm control is operating effectively
• Review evidence of continuous monitoring for IR-4(10)
• Verify enhancement builds upon base control IR-4

How to Test

Step 1: Review Documentation

Examine the System Security Plan (SSP) and related artifacts for IR-4(10) 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.

Control Statement

Coordinate incident handling activities involving supply chain events with other organizations involved in the supply chain.

Implementation Guidance
