ISO/IEC 27017 provides guidelines for information security controls applicable to the provision and use of cloud services by adding cloud-specific implementation guidance (based on ISO/IEC 27002) and additional controls related to cloud services. These FAQs cover what teams actually need: how to use ISO 27017 with ISO 27001, how to define shared responsibility, and how to build evidence that survives audits and customer assurance reviews.
ISO/IEC 27017 is a code of practice for information security controls for cloud services. It provides additional cloud-specific implementation guidance for relevant controls specified in ISO/IEC 27002, and adds controls that specifically relate to cloud services.
It is written for both cloud service providers and cloud service customers, with guidance that helps clarify roles and responsibilities across the shared responsibility boundary.
ISO/IEC 27001 defines ISMS requirements. ISO/IEC 27002 provides a control catalogue and guidance. ISO/IEC 27017 adds cloud-specific guidance on top of the ISO/IEC 27002 control baseline for organizations that provide or use cloud services.
In practice, many teams map ISO 27017 guidance into their ISO 27001 Statement of Applicability and cloud operating procedures.
ISO 27017 succeeds when you can show evidence that the responsibility model is operating in practice. Auditors and customer security reviewers tend to ask for the same artifacts.
Evidence quality matters more than volume: it should be current, attributable, and traceable to control operation.
Yes. ISO 27017 provides guidance for both cloud service providers and cloud service customers. Providers use it to define and operate cloud control responsibilities and disclosures. Customers use it to define what they must do inside their tenant and what they must require from providers (and validate with evidence).
The most effective implementations use one shared responsibility model that both parties can explain.
ISO 27017 is a code of practice and guidance standard. Organizations commonly use it to strengthen their ISO 27001 controls for cloud environments and to support assurance conversations with customers and procurement teams.
If you need certification outcomes, the practical path is usually ISO 27001 certification with clear cloud scope and evidence that ISO 27017 guidance is implemented where relevant.
Data location and jurisdiction questions are central in cloud risk and procurement. Providers should disclose relevant geographic locations where customer data can be stored or processed. Customers should use that disclosure to determine relevant supervisory authorities and legal constraints.
Record the decision and refresh it when regions, services, or data classifications change.
The most common pitfall is writing a responsibility matrix but not operating it. The second is collecting evidence without tying it to responsibilities and control operation.
Treat ISO 27017 like an operating model for cloud controls and evidence, not a policy exercise.
Start with shared responsibility and three evidence-heavy control themes: access administration, logging/monitoring, and data lifecycle (backup/restore and deletion). Then expand outward.
This creates immediate risk reduction and makes audits and procurement reviews much easier.
