SR-5(1) Adequate Supply

Enhancement of: SR-5

High-Level Description

Family: Supply Chain Risk Management (SR) Framework: NIST SP 800-53 Rev 5

Adversaries can attempt to impede organizational operations by disrupting the supply of critical system components or corrupting supplier operations. Organizations may track systems and component mean time to failure to mitigate the loss of temporary or permanent system function. Controls to ensure that adequate supplies of critical system components include the use of multiple suppliers throughout the supply chain for the identified critical components, stockpiling spare components to ensure operation during mission-critical times, and the identification of functionally identical or similar components that may be used, if necessary.

What to Check

• Verify SR-5(1) Adequate Supply is documented in SSP
• Confirm control is operating effectively
• Review evidence of continuous monitoring for SR-5(1)
• Verify enhancement builds upon base control SR-5

How to Test

Step 1: Review Documentation

Examine the System Security Plan (SSP) and related artifacts for SR-5(1) 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.
