Organizations are expected to identify high-impact suppliers, assess and prioritize related risks, and integrate security requirements into contracts and lifecycle oversight. Sources: [ACN baseline obligations determination](https://www.acn.gov.it/portale/documents/d/guest/detacn_obblighi_2511-v3_signed), [ACN baseline reading guide](https://www.acn.gov.it/portale/documents/d/guest/guida-alla-lettura-specifiche-di-base) ## Key takeaways - Supply-chain controls are formalized through GV.SC baseline measures. - Critical suppliers should be identified, prioritized, and tracked in a maintained inventory. - Security requirements should be embedded in tendering and contractual documents. - Supplier risk must be evaluated, treated, and monitored throughout the procurement lifecycle.

Governance and policy baseline (GV.SC-01) Define and approve supply-chain cyber-risk governance principles and requirements for high-impact procurements. ### 2. Roles and accountability (GV.SC-02) Assign clear responsibilities across internal stakeholders and define interaction rules with suppliers, partners, and customers where relevant. ### 3. Supplier inventory and prioritization (GV.SC-04) Maintain an updated inventory of suppliers linked to potentially high-impact supplies and prioritize them by criticality. ### 4. Contractual security integration (GV.SC-05) Integrate required security clauses and control expectations into bids, contracts, agreements, and procurement artifacts. ### 5. Lifecycle supplier-risk oversight (GV.SC-07) Evaluate, treat, and continuously monitor supplier-related cyber risks during the full supply lifecycle.

Build or refresh inventory of high-impact suppliers and assign owners. 2. Define supplier criticality criteria and scoring method. 3. Update procurement templates with required cybersecurity clauses. 4. Launch prioritized supplier-risk assessments and treatment plans. 5. Establish recurring monitoring and reassessment cadence. ## FAQ ### Is supplier cybersecurity a technical-only responsibility? No. Baseline requirements place it under governance, procurement, legal, and security coordination. Source: [ACN baseline obligations determination](https://www.acn.gov.it/portale/documents/d/guest/detacn_obblighi_2511-v3_signed) ### Are contract clauses sufficient by themselves? No. Clauses must be backed by risk assessment, treatment decisions, and ongoing monitoring. Source: [ACN baseline obligations determination](https://www.acn.gov.it/portale/documents/d/guest/detacn_obblighi_2511-v3_signed) ### Which suppliers should be assessed first? Priority should follow documented criticality and risk criteria defined by the organization and aligned with baseline expectations.
