Fedramp Supply Chain Risk Management Plan

Standard Operating Procedure: FedRAMP Supply Chain Risk Management (SCRM)

1. Document Control Block

• Document ID: TR-SCRM-001-A
• Effective Date: 2023-10-27
• Version: 2.1.0
• Review Cadence: Annual or upon significant infrastructure change
• Target Audience: Security Operations (SecOps), Procurement, Legal, and DevOps Engineering

2. Executive Summary & Scope

This document defines the mandatory protocol for identifying, assessing, and mitigating risks within the Template Registry information system supply chain. This procedure aligns with NIST SP 800-161 (Supply Chain Risk Management Practices for Federal Information Systems and Organizations) and fulfills FedRAMP SR-1, SR-2, and SR-3 control requirements. This scope covers all third-party software, hardware, and service providers (Cloud Service Providers/Vendors) integrated into the Template Registry production environment.

3. Prerequisites & Tool Requirements

• Software/Access: Access to the GRC platform (e.g., Archer, Drata, or internal Jira Security module), Vendor Risk Assessment portal.
• Certifications: Personnel must hold current CISM, CISSP, or equivalent certification; knowledge of NIST SP 800-53 Rev 5 required.
• Regulatory Framework: Possession of current FedRAMP SSP (System Security Plan) and relevant POA&Ms.

5. Step-by-Step Operational Procedure

Phase I: Supplier Identification & Due Diligence

• Catalog all critical vendors and software components (SBoM verification).
• Distribute FedRAMP SCRM questionnaires to prospective vendors.
• Review external audit reports (SOC 2 Type II, FedRAMP authorization package) for compliance gaps.

Phase II: Risk Assessment & Mitigation

• Perform threat modeling on vendor integration points (APIs, data feeds).
• Map vendor security controls against NIST 800-53 supply chain controls (SR family).
• Assign residual risk ratings (High/Moderate/Low) to every vendor in the GRC register.

Phase III: Continuous Monitoring & Lifecycle Management

• Conduct semi-annual vendor security performance reviews.
• Monitor CVE databases (NVD) for vulnerabilities specifically affecting the vendor software stack.
• Update SBoM (Software Bill of Materials) upon every major deployment or vendor software update.

6. Quality Assurance & Verification Criteria

• Audit Threshold: 100% of "High" impact vendors must have a current, verified SOC 2/FedRAMP authorization on file.
• SBoM Accuracy: 95% threshold for component identification; any unidentified "shadow IT" component triggers a non-conformance event.
• Response Benchmark: Any identified supply chain vulnerability rated CVSS 7.0+ must be mitigated or accepted by the authorizing official within 30 days.

7. Practical Troubleshooting Scenarios

Scenario A: Vendor Loses FedRAMP Authorization

• Immediate Protocol: Immediately isolate vendor integration from production environment. Initiate "Vendor Contingency Plan" to move to secondary provider or revert to local/on-prem equivalent. Notify the FedRAMP PMO within 24 hours.

Scenario B: Critical Vulnerability (Log4j equivalent) detected in third-party library

• Immediate Protocol: Identify all instances via SBoM. Deploy compensating controls at the WAF (Web Application Firewall) level within 4 hours. Schedule emergency patch deployment or initiate vendor support ticket to force an update.

Scenario C: Unauthorized Sub-processor identified in data chain

• Immediate Protocol: Freeze all data transit with the primary vendor. Conduct expedited audit of the new sub-processor. If non-compliant, terminate connection until a formal Business Associate Agreement (BAA) and security assessment are signed.
