Episode 136 — Spotlight: Supply Chain Controls and Processes (SR-3)

Supply Chain Controls and Processes (SR-3) ensure that products and services acquired or integrated into an organization’s environment meet established security and privacy requirements throughout their lifecycle. For exam purposes, understand that SR-3 requires identifying supply chain risks early—before acquisition—and embedding security criteria into procurement, contracting, and performance management. This includes defining control requirements for vendors, verifying the integrity of delivered components, and maintaining traceability from origin to deployment. SR-3 also mandates documented processes for supplier evaluation, ongoing assurance, and response to discovered vulnerabilities or counterfeit components. The objective is to prevent compromises that originate from unverified suppliers, tampered hardware, or insecure software updates.

Operationally, organizations apply SR-3 through formal supplier onboarding procedures, contract clauses mandating adherence to NIST 800-53 or equivalent frameworks, and secure delivery verification steps such as digital signatures and tamper-evident packaging. Supplier audits, third-party attestations, and continuous monitoring ensure obligations remain current. Evidence includes supplier assessments, delivery acceptance records, risk treatment plans, and component authenticity certificates. Metrics such as percentage of suppliers with completed risk assessments, number of nonconforming deliveries detected, and remediation turnaround time measure program maturity. Common pitfalls include relying solely on vendor assurances, failing to track subcontractors, and neglecting verification at the integration stage. Mastering SR-3 demonstrates the ability to operationalize trust, ensuring that supply chain controls are continuous, documented, and enforceable across all tiers.
