SR-6 Supplier Assessments and Reviews

High-Level Description

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

An assessment and review of supplier risk includes security and supply chain risk management processes, foreign ownership, control or influence (FOCI), and the ability of the supplier to effectively assess subordinate second-tier and third-tier suppliers and contractors. The reviews may be conducted by the organization or by an independent third party. The reviews consider documented processes, documented controls, all-source intelligence, and publicly available information related to the supplier or contractor. Organizations can use open-source information to monitor for indications of stolen information, poor development and quality control practices, information spillage, or counterfeits. In some cases, it may be appropriate or required to share assessment and review results with other organizations in accordance with any applicable rules, policies, or inter-organizational agreements or contracts.

What to Check

  • Verify SR-6 Supplier Assessments and Reviews is documented in SSP
  • Confirm control is operating effectively
  • Review evidence of continuous monitoring for SR-6

How to Test

Step 1: Review Documentation

Examine the System Security Plan (SSP) and related artifacts for SR-6 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.
