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

• Verify SR-3(2) Limitation of Harm is documented in SSP
• Confirm control is operating effectively
• Review evidence of continuous monitoring for SR-3(2)
• Verify enhancement builds upon base control SR-3

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.
