SR-3(2) Limitation of Harm
Enhancement of: SR-3
High-Level Description
Family: Supply Chain Risk Management (SR)
Framework: NIST SP 800-53 Rev 5
Controls that can be implemented to reduce the probability of adversaries successfully identifying and targeting the supply chain include avoiding the purchase of custom or non-standardized configurations, employing approved vendor lists with standing reputations in industry, following pre-agreed maintenance schedules and update and patch delivery mechanisms, maintaining a contingency plan in case of a supply chain event, using procurement carve-outs that provide exclusions to commitments or obligations, using diverse delivery routes, and minimizing the time between purchase decisions and delivery.
What to Check
How to Test
Step 1: Review Documentation
Examine the System Security Plan (SSP) and related artifacts for SR-3(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.
