Framework: NIST 800-53 Audio Course

Supply Chain Risk Management Plan (SR-2) establishes how organizations identify, assess, and mitigate risks arising from suppliers, service providers, and dependencies. For exam purposes, understand that SR-2 formalizes governance: roles, risk criteria, review cadence, escalation procedures, and reporting. The plan must define integration points with procurement, asset management, and incident response. It outlines processes for tiering suppliers by criticality, assigning control requirements, and maintaining current assurance documentation. SR-2 ensures that supply chain security is systematic and consistent, not reactive or vendor-specific.

Operationally, organizations maintain an SR-2 plan aligned with enterprise risk management frameworks. The plan includes supplier inventories, risk scoring methods, communication channels, and contractual security clauses. Annual reviews ensure relevance as supply relationships and threat environments evolve. Evidence includes approved plan documents, version histories, risk tiering tables, and governance meeting minutes. Metrics such as plan update frequency, supplier risk coverage percentage, and time to incorporate new suppliers measure program maturity. Pitfalls include siloed planning within procurement teams, unapproved deviations from policy, and lack of integration with monitoring or incident management. Mastery of SR-2 demonstrates that supply chain oversight operates with the same rigor as internal control programs—planned, measurable, and continually improved.
