ISO/IEC 27017
ISO/IEC 27017 cloud security guide for providers and customers, covering shared responsibilities, the seven 2015 cloud controls, evidence, and edition changes.
ISO/IEC 27017:2015 is a code of practice that adds cloud-specific guidance to ISO/IEC 27002 and seven cloud controls. It provides guidance for both and .
ISO lists ISO/IEC 27017:2015 as withdrawn and replaced by ISO/IEC 27017:2026. The detailed control mappings in this hub cover the 2015 edition; obtain the 2026 text before using its revised guidance or mapping its controls. ISO/IEC 27017 does not replace ISO/IEC 27001, transfer a customer's legal or contractual responsibilities to its provider, or create a standalone management-system certification scheme. Define the service, provider/customer roles, contract boundary, risk treatment, and evidence for each control, and record the source and target editions in every map.
Allocate provider, customer, and shared activities for the actual service and trace upstream providers.
Match provider assurance and contract claims to customer configuration, access, logging, changes, incidents, and exit evidence.
Map the 2015 guidance into the ISMS with source and target editions explicit; do not treat it as a standalone certification.
Assign the seven CLD controls to the provider, customer, or both, with agreement terms and evidence for the actual service.
Record provider, customer, and shared duties for each service; a company can be a customer upstream and a provider downstream.
Test claims against contract terms, independent assurance, configuration evidence, privileged-access reviews, logs, changes, incidents, and exit records.
Use the 2015 code of practice as implementation guidance within a risk-based ISMS; ISO/IEC 27001 remains the certifiable requirements standard.
Cover shared roles, customer-asset removal, virtual-environment segregation, virtual-machine hardening, administrator operations, service monitoring, and virtual/physical network alignment.
Start with the provider/customer relationship and responsibility split. Then map risk-selected controls, test contractual and operational evidence, and use comparisons only for the assurance question they actually answer.
Understand what ISO/IEC 27017 is, who it addresses, and why responsibility depends on the service and agreement.
Connect cloud risks and provider capabilities to the ISMS, contract, customer configuration, and accountable owners.
Build an assurance pack that shows whether contracted and customer-managed controls are operating, current, and reviewable.
Use each comparison to understand purpose and evidence coverage; none makes the other framework automatically satisfied.
