ISO/IEC 27017 Code of Practice for Cloud Security Controls

Overview

Our ISO/IEC 27017 consultancy services support organisations in strengthening information security controls for cloud services, whether they are cloud service providers, cloud service customers, or both.

CCIS works closely with organisations to translate ISO/IEC 27017 guidance into practical cloud security practices, helping teams clarify shared security responsibilities, manage cloud‑specific risks, and integrate cloud controls into existing information security management processes in a structured and sustainable way.

What is ISO/IEC 27017?

ISO/IEC 27017 is an international code of practice that provides cloud‑specific information security guidance for organisations using or providing cloud services.

It builds on ISO/IEC 27001 and ISO/IEC 27002 by introducing additional controls and implementation guidance tailored to cloud computing environments. ISO/IEC 27017 helps organisations address shared responsibility models, clarify security roles between cloud providers and customers, and manage risks related to cloud service configuration, operation, and oversight.

Relationship with ISO/IEC 27001

ISO/IEC 27017 is designed to be implemented in conjunction with ISO/IEC 27001.

While ISO/IEC 27001 establishes the Information Security Management System (ISMS) framework, ISO/IEC 27017 provides additional cloud‑specific guidance to enhance control implementation and effectiveness.

Together, these standards support a structured and comprehensive approach to managing information security risks in cloud environments.

Benefits of ISO/IEC 27017

Implementing ISO/IEC 27017 helps organisations improve governance and control over information security in cloud environments.

Organisations benefit from clearer definition of cloud security responsibilities, more consistent implementation of cloud‑specific controls, and improved management of risks associated with cloud service usage. ISO/IEC 27017 also enhances confidence among customers, partners, and stakeholders by demonstrating a structured and responsible approach to securing information processed in the cloud, while supporting alignment with broader information security and compliance expectations.

Our Consultancy Approach

At CCIS, we provide practical and structured consultancy services tailored to your organisation’s size, industry, and operational context.

Our consultancy covers the full lifecycle of implementation, including an initial gap analysis to understand current practices, support for management system design and documentation, guidance on implementation and record‑keeping processes, practical training and awareness for relevant personnel, internal audit support, and assistance in preparing for certification or assessment.

We continue to support organisations beyond certification to help ensure management systems remain effective, compliant, and audit‑ready as business needs and requirements evolve. Our focus is on effective implementation and long‑term sustainability, not documentation created solely for audit purposes.
