ISO 27017
ISO/IEC 27017 — Cloud Security Controls
Security controls for cloud service providers and customers
What is ISO 27017?
ISO/IEC 27017 provides guidelines for information security controls applicable to the provision and use of cloud services. It builds upon ISO 27002 by providing additional implementation guidance specific to cloud computing environments.
The standard defines responsibilities for both cloud service providers (CSPs) and cloud service customers (CSCs), ensuring clear delineation of security responsibilities in the shared responsibility model.
ISO 27017 is implemented as an extension to an existing ISO 27001 ISMS, adding cloud-specific controls that address unique risks associated with cloud computing environments.
Key Highlights
- Extension to ISO 27001/27002 for cloud-specific security
- Defines controls for both cloud providers and cloud customers
- Addresses the shared responsibility model in cloud computing
- Covers 37 controls from ISO 27002 with cloud guidance plus 7 new cloud controls
- Applicable to public, private, and hybrid cloud deployments
- Complements ISO 27018 for cloud privacy
Why is ISO 27017 Important?
As organizations increasingly adopt cloud services, traditional security controls may not adequately address cloud-specific risks such as multi-tenancy, data residency, and shared infrastructure vulnerabilities.
Cloud Risk Mitigation
Address cloud-specific security risks that traditional information security frameworks may not fully cover.
Clear Responsibilities
Define and document security responsibilities between cloud service providers and customers.
Customer Assurance
Demonstrate to customers that your cloud services meet international security standards.
Regulatory Alignment
Meet cloud security requirements demanded by regulators and industry standards.
Competitive Edge
Differentiate your cloud services with internationally recognized security certification.
How ISO 27017 Works
ISO 27017 implementation adds cloud-specific controls to your existing ISO 27001 ISMS, typically requiring 3-4 months of additional effort.
Identify Cloud Services
Inventory all cloud services used or provided, including SaaS, PaaS, and IaaS deployments across your organization.
Define Shared Responsibilities
Map security responsibilities between your organization and cloud service providers using the shared responsibility model.
Cloud Risk Assessment
Assess cloud-specific risks including data residency, multi-tenancy, virtualization, and service availability.
Implement Cloud Controls
Implement the 7 additional cloud-specific controls and enhanced guidance for existing ISO 27002 controls in cloud contexts.
Service Level Agreements
Review and strengthen cloud service agreements to include security requirements, incident response, and data handling provisions.
Monitoring and Audit
Establish cloud security monitoring, logging, and audit mechanisms for cloud environments.
Certification
Extend the ISO 27001 certification scope to include ISO 27017 cloud security controls through an accredited certification body.
