Question 1

How does ISO/IEC 27036 apply to cloud suppliers?

Treat cloud as a supplier relationship with and perspectives. Apply ISO/IEC 27036-2:2022 relationship requirements and ISO/IEC 27036-4:2016 cloud guidance, then document how responsibility changes with the service and deployment model, configuration, data, interfaces, and nested cloud services. Part 4 is guidance and does not replace cloud-specific law, regulation, sector rules, or contractual duties.

The provider's controls do not remove the customer's responsibilities. For the actual service, record who manages identities, privileged access, configuration, logging, encryption, backups, vulnerability response, incident communication, and data return or disposal. Check legal and contractual duties separately.

  • Classify the information and business process before selecting the service; record sensitivity, criticality, permitted locations, and applicable restrictions.
  • Map customer-managed and provider-managed controls for the actual service, including administrator and user access and any multi-tenant separation requirements.
  • Identify cloud services used by the provider and decide what visibility, assurance, change notice, incident support, continuity, portability, and exit evidence the relationship needs.

Part 2 supplies the fundamental requirements for planning, selecting, agreeing, monitoring, changing, and terminating a cloud supplier relationship.

ISO/IEC 27036-4:2016 standard page

Part 4 provides cloud customer and provider guidance on shared responsibilities, assurance, information location, service changes, incidents, asset transfer, and disposal.

Question 2

What should be checked before accepting the cloud service?

Review the service description, responsibility model, standard terms, service levels, data and administrative paths, provider locations, subprocessors or nested cloud services, change-notice process, available logs, assurance scope, backup and recovery capabilities, incident support, portability, and termination process.

Acceptance evidence should relate to the subscribed service and configuration. Organization-wide certification can support the decision, but it does not by itself show that the selected service, region, controls, or customer configuration meets the requirement. Public, hybrid, and private deployment labels do not settle the risk: information importance, customer control, location, privileged access, separation, logging, portability, and the actual allocation of responsibility still matter.

  • Record non-negotiable standard-term gaps and the compensating control, risk approval, or alternative service decision.
  • Test data export, restoration, administrative access, logging, and required interfaces before critical reliance where proportionate.
  • Treat portability and deletion as verifiable exit requirements, not assumptions based on a marketing description.

Part 4 identifies cloud-specific acquisition issues including responsibilities, assurance, separation, asset transfer, service changes, and disposal confirmation.

Question 3

How should cloud changes, incidents, and exit be handled?

Monitor service and provider changes against the agreed responsibility map and risk decision. Define which changes require notice, review, approval, reconfiguration, or migration. The customer and provider should also agree incident contacts and the information needed for impact assessment and response.

Before termination, export and verify required information, transfer service where needed, revoke access and integrations, and obtain the agreed evidence of disposal. Part 4 addresses cloud information return and disposal, but it does not itself provide business-continuity management guidance; use the agreement, applicable obligations, and relevant continuity standards for that work.

  • Keep change notices, impact assessments, incident records, configuration decisions, export results, and disposal confirmation with the relationship record.
  • Check backups, retained logs, legal holds, and technical deletion limits rather than promising immediate deletion in every system.
  • Close the relationship only after owners verify transition, access removal, asset handling, surviving duties, and approved exceptions.
