ISO 27017 Control Mapping to ISO 27001

Map ISO/IEC 27017 cloud guidance into an ISO/IEC 27001 ISMS that auditors can follow.

Focus on SoA entries, shared responsibility, and evidence artifacts - not generic mapping tables.

Overview

Most organizations implement ISO/IEC 27017 as cloud-sector guidance on top of their ISO/IEC 27001 ISMS. A good mapping connects the cloud responsibility boundary to control ownership and evidence. This page gives a mapping method you can apply across IaaS, PaaS, and SaaS, and shows how to translate concrete ISO 27017 themes such as shared roles and responsibilities, asset return at termination, segregation in shared virtual environments, and alignment of virtual and physical network security into SoA wording and audit-ready artifacts.

Section 1

Mapping principle: ISO 27017 strengthens the cloud story for ISO 27001

ISO/IEC 27017 provides cloud-specific implementation guidance for controls based on ISO/IEC 27002, plus additional controls for cloud services.

ISO/IEC 27001 auditors typically look for: defined scope, risk treatment, SoA justification, control operation, and evidence. ISO 27017 helps you make cloud-specific responsibility and control operation explicit.

  • Map cloud guidance into SoA language and control procedures (not just a spreadsheet)
  • Attach a responsibility matrix to each relevant control so ownership is unambiguous
  • Define evidence expectations per control (logs, tests, approvals, reviews)
Section 2

Step-by-step mapping method (repeatable for every cloud service)

Use this method per cloud service or per cloud platform landing zone. Keep the mapping versioned and update it when the service model changes.

Make the mapping operational: every mapped control should produce evidence on a cadence.

  • 1) Identify the cloud service model (IaaS/PaaS/SaaS) and define the responsibility boundary
  • 2) Select relevant ISO 27002 controls and add ISO 27017 cloud-specific guidance as implementation requirements
  • 3) Update SoA: applicability, justification, and reference to cloud procedures and agreements
  • 4) Assign owners: provider-side owner (where applicable), customer-side owner, and evidence producer
  • 5) Define evidence: what will be collected, where it lives, retention, and sampling approach
  • 6) Define operating cadence: reviews, tests, restore exercises, access reviews, and corrective actions
Section 3

Examples: cloud-specific mapping patterns that auditors understand

These examples show how ISO 27017 guidance often appears in an ISO 27001 audit story. Use them as templates and tailor to your provider/customer split.

Treat each example as a pattern: procedure + owner + evidence + cadence.

  • Asset inventory and data categories: explicitly identify cloud customer data and cloud-derived data; document ownership and handling
  • Information classification and labeling: customer procedure + provider functionality disclosures that support classification/labeling in the service
  • Access control for cloud network services: customer policy specifying access requirements per cloud service and evidence of enforcement
  • Geographic data locations: provider disclosures captured as evidence and assessed for jurisdiction and legal constraints
  • Backups, recovery, and secure deletion: ownership and verification method documented; restore tests and deletion attestations retained
  • Asset return and removal at termination: agreement clauses, termination procedure, and proof of timely return, removal, and deletion
  • Shared virtual environments: segregation controls, virtual-machine hardening, and evidence that customer and provider admin boundaries are protected
Section 4

Deliverables checklist (what to produce for audits and assurance)

If you can produce these artifacts consistently, your ISO 27001 audits and customer assurance reviews become dramatically easier.

Build once, reuse everywhere: procurement, security reviews, and audit cycles.

  • Cloud shared responsibility matrix (IaaS/PaaS/SaaS) tied to your control set
  • SoA entries that reference cloud procedures, agreements, and evidence locations
  • Evidence index: what exists, where it lives, and the review cadence
  • Exception register for cloud control deviations with approvals and remediation plans
