ISO 27017 Cloud Security Control Advisory

What we assess

We examine how security responsibilities are divided between provider and customer and how those commitments are implemented. The review connects cloud architecture, administration, configuration, operational procedures, and supplier assurances with existing information-security controls. Confirm the intended assurance or certification pathway with the relevant independent body.

Evidence to prepare

• Cloud service inventory, architecture diagrams, and shared-responsibility matrices.
• Administrative access, tenant separation, configuration management, and operational procedures.
• Provider agreements, monitoring records, incident coordination, and control review evidence.

Keep design evidence separate from operating evidence. An approved procedure shows how a control is designed; dated records show whether it ran consistently over the review period. Evidence should identify its source, owner, scope, and collection date.

What you receive

• Cloud control applicability and responsibility map.
• Readiness gaps with provider and customer remediation owners.
• Evidence recommendations aligned to the existing ISMS and buyer requirements.

Common questions

Does our cloud provider’s certification cover our application?

Provider assurance can support inherited controls, but customer responsibilities remain. Review the covered services and your application, identity, data, and configuration controls separately.

What determines the engagement timeline and cost?

The system boundary, number of entities and locations, existing control maturity, evidence availability, and assessment pathway determine the effort. Share your customer requirements and target milestone so we can define a realistic scope before proposing a schedule.
