Supply Chain Risk Management Plan Nist

Standard Operating Procedure: Supply Chain Risk Management (SCRM)

Document Control Block

• Document ID: SOP-OPS-SCRM-001
• Effective Date: 2023-10-27
• Version: 2.1.0
• Review Cadence: Semi-Annual (Q2/Q4)
• Target Audience: Procurement, Cyber-Security Operations, Legal/Compliance, Vendor Risk Management (VRM) Teams.

1. Executive Summary & Scope

This SOP establishes the operational framework for identifying, assessing, and mitigating risks associated with the Template Registry supply chain. This procedure aligns with NIST SP 800-161 (Supply Chain Risk Management Practices for Federal Information Systems and Organizations) and NIST CSF 2.0 (Supply Chain Risk Management Category). The scope encompasses all hardware, software, and managed service providers (MSPs) integrated into the organizational technology stack.

2. Prerequisites & Tool Requirements

• Software Access: Access to GRC (Governance, Risk, and Compliance) platform, static/dynamic code analysis (SAST/DAST) tools, and SBOM (Software Bill of Materials) repositories.
• Certifications: Personnel conducting assessments must hold CTPRP (Certified Third-Party Risk Professional) or equivalent.
• Documentation: Access to current Vendor Master List and critical business process dependency maps.

4. Step-by-Step Operational Procedure

Phase 1: Supplier Identification & Categorization

• Tier vendors based on data access levels (Tier 1: Critical/Systemic, Tier 2: Operational, Tier 3: Commodity).
• Map third-party dependencies against internal business-critical workflows.
• Verify vendor’s alignment with NIST 800-53 security controls.

Phase 2: Vulnerability Assessment & Analysis

• Request and validate Software Bill of Materials (SBOM) for all integrated software.
• Execute automated scanning for Common Vulnerabilities and Exposures (CVEs) within the supply chain.
• Evaluate vendor-provided SOC2 Type II reports for control failures.

Phase 3: Mitigation & Monitoring

• Implement "Least Privilege" access controls for all third-party integrations.
• Configure automated real-time monitoring for vendor security posture changes.
• Establish "Kill Switch" protocols for immediate termination of high-risk connectivity.

---

5. Quality Assurance & Verification Criteria

• Audit Threshold: 100% of Tier 1 vendors must have a current, valid SBOM on file.
• Verification Benchmark: Any vulnerability rated CVSS 7.0 or higher must trigger a remediation plan within 72 hours.
• Acceptance Criteria: Procurement cannot execute contracts without written approval from the Cyber-Security Lead verifying adherence to NIST SP 800-161 standards.

6. Practical Troubleshooting Scenarios

Scenario A: Vendor Refusal of SBOM Disclosure

• Observation: Vendor cites proprietary restrictions for denying SBOM requests.
• Corrective Action: Escalate to Procurement/Legal. Initiate manual code penetration testing on integration endpoints. If refusal persists, categorize vendor as "High Residual Risk" and restrict data connectivity to a sandboxed environment.

Scenario B: Critical CVE Detected in Upstream Library

• Observation: Security monitoring alerts to a Log4j-style zero-day within a Tier 1 dependency.
• Corrective Action: Trigger "Incident Response Plan: Supply Chain." Isolate the affected integration within 60 minutes. Apply vendor-provided patches or deploy WAF (Web Application Firewall) signatures as a compensating control until permanent patching is validated.

Scenario C: Sudden Degradation of Vendor Security Score

• Observation: Third-party monitoring tool reports a breach or significant compliance drift at a critical partner.
• Corrective Action: Suspend API connectivity. Require an immediate "Incident Audit Report" from the vendor. Present findings to the Risk Committee for a decision on contract termination or continuation under enhanced oversight.
