ISO 27017 Details
What It Is
ISO/IEC 27017:2015 is a code of practice extending ISO/IEC 27002 with cloud-specific information security controls. Its primary purpose is to provide implementation guidance for securing cloud services across public, private, and hybrid models, focusing on shared responsibilities between cloud service providers (CSPs) and cloud service customers (CSCs). It adopts a risk-based approach integrated into an ISO 27001 ISMS.
Key Components
- Guidance on 37 ISO 27002 controls adapted for cloud environments.
- Seven additional cloud-specific controls (e.g., CLD.6.3.1 for shared roles, CLD.9.5.1 for virtual segregation).
- Covers domains like access control, operations security, and supplier relationships.
- Not standalone certifiable; assessed within ISO 27001 audits.
Why Organizations Use It
Organizations adopt it for cloud risk management, regulatory alignment (e.g., GDPR), and procurement advantages. It reduces multi-tenancy risks, builds customer trust, and differentiates CSPs in competitive markets.
Implementation Overview
Integrate into existing ISO 27001 ISMS via risk assessment, control mapping, and cloud configuration hardening. Suitable for CSPs, CSCs of all sizes; involves joint audits (9-12 months). Requires operational maturity in monitoring and virtualization.
