ISO/IEC 27017
Provider and customer split
Allocate provider, customer, and shared activities for the actual service and trace upstream providers.
Assurance evidence
Match provider assurance and contract claims to customer configuration, access, logging, changes, incidents, and exit evidence.
ISO/IEC 27001 mapping
Map the 2015 guidance into the ISMS with source and target editions explicit; do not treat it as a standalone certification.
Seven additional controls
Assign the seven CLD controls to the provider, customer, or both, with agreement terms and evidence for the actual service.

Read the standard as cloud-specific guidance, not a universal checklist: control selection depends on risk plus legal, regulatory, contractual, and service-specific requirements.

What this hub helps you do
Provider and customer split
Record provider, customer, and shared duties for each service; a company can be a customer upstream and a provider downstream.
Assurance evidence
Test claims against contract terms, independent assurance, configuration evidence, privileged-access reviews, logs, changes, incidents, and exit records.
ISO/IEC 27001 mapping
Use the 2015 code of practice as implementation guidance within a risk-based ISMS; ISO/IEC 27001 remains the certifiable requirements standard.
Seven additional cloud controls
Cover shared roles, customer-asset removal, virtual-environment segregation, virtual-machine hardening, administrator operations, service monitoring, and virtual/physical network alignment.

It does not replace ISO/IEC 27001, transfer a customer's applicable legal or contractual responsibilities to its provider, or create a standalone management-system certification scheme. Start by defining the service, provider/customer roles, contract boundary, risk treatment, and evidence available for each control. ISO currently lists Edition 2 as under publication and says it will replace the 2015 edition. Record the edition used for every control map.

Recommended reading path

Move from service scope to operating evidence

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.
