ISO/IEC 27017 explained

ISO/IEC 27017 is a security standard developed for cloud service providers and users to make a safer cloud-based environment and reduce the risk of security problems.^[1] It was published by the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC) under the joint ISO and IEC subcommittee, ISO/IEC JTC 1/SC 27.^[2] It is part of the ISO/IEC 27000 family of standards, standards which provides best practice recommendations on information security management. This standard was built from ISO/IEC 27002, suggesting additional security controls for the cloud which were not completely defined in ISO/IEC 27002.

This International Standard provides guidelines supporting the implementation of information security controls for cloud service customers, who implements the controls, and cloud service providers to support the implementations of those controls.^[3] The selection of appropriate information security controls and the application of the implementation guidance provided, will depend on a risk assessment and any legal, contractual, regulatory or other cloud-sector specific information security requirements.^[4]

What does the standard provide?

ISO/IEC 27017 provides guidelines for information security controls applicable to the use of cloud services by providing an additional implementation guidance for 37 controls specified in ISO/IEC 27002 and 7 additional controls related to cloud services which address the following:

• Who is responsible for what between the cloud service provider and the cloud customer.
• The removal or return of assets at the end of a contract.
• Protection and separation of the customer's virtual environment.
• Virtual machine configuration.
• Administrative operations and procedures associated with the cloud environment.
• Cloud customer monitoring of activity.
• Virtual and cloud network environment alignment.^[5]
