Practical answer with owners, evidence, review triggers, and external source references. *FAQ* *Global* *ISO/IEC 27017* ## ISO/IEC 27017 FAQ Shared Responsibility How should teams handle Shared Responsibility under ISO/IEC 27017 Cloud Security Controls? Grounded in external ISO, NIST, EU, or framework sources where relevant. This is practical implementation guidance, supporting implementation planning and should be validated against jurisdiction-specific legal, contractual, and policy requirements before implementation. This ISO/IEC 27017 FAQ explains shared responsibility in practical terms: the cloud provider, customer, and other third parties must define who owns each control, record the split, and keep it current. ## How should teams handle Shared Responsibility under ISO/IEC 27017? Start with the operational decision: define what Shared Responsibility means in your ISO/IEC 27017 scope, who owns it, and what record proves the decision is current. In practice, this means documenting the split between the cloud provider and the customer before asking for evidence. NIST CSF 2.0 says cybersecurity roles and responsibilities for suppliers, customers, and partners should be established, communicated, and coordinated internally and externally, so the answer should show which party owns platform, service, configuration, access, monitoring, or incident duties. - Name the accountable owner and reviewer for Shared Responsibility. - Record the scope, assumptions, decision, approval date, evidence location, exception status, and next review trigger. - Show a simple split, such as provider-owned service controls and customer-owned configuration, access, and local process controls, then link that split to the supporting agreement or matrix. - Escalate when Shared Responsibility changes risk acceptance, service commitments, customer promises, regulatory duties, or certification evidence.

The evidence should show the process operating. For this artifact, the strongest record usually includes shared-responsibility matrix, cloud service agreement, provider assurance, customer configuration evidence, access reviews, logs, and change records. Avoid evidence that only repeats a requirement. A reviewer should be able to see the actual owner, date, system, supplier, AI system, service, incident, risk, or control sample behind the answer. - Use source records from the system of work, not screenshots created only for audit day. - Keep exceptions visible as risk acceptance, corrective action, or management-review input. - Update linked registers when the answer changes an owner, risk, control, service, supplier, or review date.

The person who can fund, operate, and correct the process should own the decision; governance should review consistency and exceptions. For high-impact changes, approval should include the teams affected by the evidence: security, privacy, resilience, supplier management, AI governance, legal, risk, or business service owners as relevant. - Use a named owner, named backup, and named escalation forum. - Separate preparation work from risk acceptance and final approval. - Keep approval records with the evidence rather than in disconnected email threads.

Review it at planned intervals and whenever the underlying scope, service, supplier, control, risk, AI system, personal data flow, incident process, or customer commitment changes. A stale record is worse than a short record. If the facts change, update the evidence and mark what changed so the next reviewer can trust the page. - Set a planned review date and a change-trigger rule. - Use findings to update controls, procedures, contracts, risk registers, or training. - Carry unresolved items into management review or risk acceptance.
