Cyber Supply Chain Risk Management Plan

Standard Operating Procedure: Cyber Supply Chain Risk Management (C-SCRM)

1. Document Control Block

2. Executive Summary & Scope

The purpose of this SOP is to define the operational framework for identifying, assessing, and mitigating risks associated with the Template Registry external supply chain. This policy mandates rigorous vetting of all software, hardware, and service providers to ensure alignment with NIST SP 800-161 guidelines and SOC2 Type II requirements. Scope covers all "Tier-1" critical dependencies, including SaaS integrations, library dependencies (OSS), and hardware infrastructure vendors.

3. Prerequisites & Tool Requirements

• Access Requirements: Administrator access to Vendor Risk Management (VRM) platform; read/write access to internal GRC portal.
• Software: Bitsight/SecurityScorecard (Third-party intelligence), Snyk (Software composition analysis), Jira (Workflow management).
• Certifications: Personnel must maintain active CTPRP (Certified Third-Party Risk Professional) or equivalent InfoSec accreditation.
• Documentation: Availability of Vendor Security Assessment Questionnaire (VSAQ) templates.

4. Roles & Responsibilities (RACI)

R = Responsible | A = Accountable | C = Consulted | I = Informed

5. Step-by-Step Operational Procedure

Phase 1: Procurement & Initial Vetting

• Verify vendor satisfies "Minimum Security Baseline" (MSB) checklist.
• Execute automated Bitsight risk assessment to verify current security posture.
• Collate and review SOC2 Type II report and Bridge Letter from vendor.

Phase 2: Technical Integration Assessment

• Run Snyk scan on all proposed proprietary vendor software/APIs.
• Evaluate "Least Privilege" access model for proposed API integration.
• Determine data residency and transit encryption standards (AES-256 mandatory).

Phase 3: Lifecycle Monitoring

• Perform quarterly automated scans of vendor infrastructure via VRM platform.
• Re-issue VSAQ annually for all mission-critical service providers.
• Validate patch management SLAs through monthly report audits.

6. Quality Assurance & Verification Criteria

• Audit Frequency: Bi-annual deep-dive audits of the Vendor Repository.
• Tolerance Thresholds:
  • Maximum allowed "SecurityScorecard" rating: B-.
  • Critical Vulnerabilities: 0-day must be patched within 48 hours; N-day must be patched within 14 days.
• Acceptance Benchmark: 100% compliance with current Template Registry Vendor Code of Conduct.

7. Practical Troubleshooting Scenarios

Scenario A: Vendor Suffers a Data Breach

• Indicator: Automated alert from security intelligence feed notifying of a breach at a Tier-1 vendor.
• Corrective Action:
  1. Immediate isolation: Disable API tokens/credentials for the affected vendor.
  2. Communication: Legal to issue a formal request for an Incident Response Report within 24 hours.
  3. Impact Analysis: InfoSec to run an audit of data exchanged with the vendor in the last 30 days to check for potential data exfiltration.

Scenario B: Vendor Fails Annual Security Assessment

• Indicator: Vendor scores below the "B-" tolerance threshold or fails to provide an updated SOC2 report.
• Corrective Action:
  1. Flag vendor as "High Risk" in the internal GRC portal.
  2. Notify Procurement to place the vendor on "Probationary Status," freezing contract expansion.
  3. Issue a formal "Cure Notice" providing a 30-day window for the vendor to remediate security gaps.
