ISO/IEC 27017:2026 PDF

Overview

ISO/IEC 27017:2026 is an international standard developed by ISO and IEC providing comprehensive guidance on information security controls for cloud services. Based on ISO/IEC 27002:2022, this standard addresses the unique challenges and requirements associated with cloud computing environments. It serves both cloud service customers (CSCs) and cloud service providers (CSPs), offering a unified approach to strengthen information security, cybersecurity, and privacy protection in cloud deployments.

This horizontal document applies to all cloud deployment models, including private, public, hybrid, and multi-cloud environments. It covers controls and practical guidance designed to support risk management, compliance, and the effective implementation of security measures tailored for the cloud context.

Key Topics

• Supplemental Guidance for ISO/IEC 27002 Controls ISO/IEC 27017:2026 adapts and extends the controls defined in ISO/IEC 27002:2022 to address technical and operational cloud-specific considerations, ensuring security requirements are effectively met for both CSCs and CSPs.

• Cloud-Specific Controls Additional controls are introduced to mitigate risks unique to cloud services, such as shared responsibility models, segregation in virtual environments, and detection/prevention of unauthorized cloud usage.

• Roles and Responsibilities The standard emphasizes the need for clear agreements and documentation of roles and responsibilities between cloud stakeholders, ensuring accountability and transparency in cloud security management.

• Risk Management in Cloud Services Guidance is provided for the management of information security risks, referencing ISO/IEC 27001 and ISO/IEC 27005 for risk-based approaches to the selection and application of security controls in cloud environments.

• Supplier Relationships Cloud service provision is addressed as a form of supplier relationship; the standard references additional guidance from the ISO/IEC 27036 series, specifically for handling the security of supply chains in cloud ecosystems.

Applications

ISO/IEC 27017:2026 is vital for organizations adopting, supplying, or managing cloud services, including:

• Cloud Service Customers (CSCs):

  • Selecting cloud providers with robust information security controls.
  • Ensuring compliance with regulatory, contractual, and internal security requirements.
  • Managing risks related to data storage, processing, and transfer in the cloud.
  • Clarifying shared responsibilities with CSPs.

• Cloud Service Providers (CSPs):

  • Demonstrating commitment to cloud information security best practices.
  • Supporting customer compliance and audit needs.
  • Implementing and maintaining security controls aligned with international standards.
  • Providing transparency on security capabilities in agreements and documentation.

• Hybrid and Multi-Cloud Deployments:

  • Coordinating security controls across diverse cloud models and multiple providers.
  • Managing complex supplier relationships and ensuring consistent risk mitigation.

Organizations using ISO/IEC 27017:2026 can enhance their trustworthiness, facilitate global business, and foster robust cloud security postures.
