ISO 27017 security controls for cloud services

ISO 27017 is an international standard that provides guidelines and recommendations for information security controls specifically related to cloud services. It is an extension of ISO 27001, which is a widely recognized framework for information security management systems (ISMS). ISO 27017 focuses on addressing the unique security challenges and considerations associated with cloud computing. Below are some of the key security controls outlined in ISO 27017 for cloud services:

  • Legal and Regulatory Compliance:

Ensure that cloud services comply with relevant laws, regulations, and contractual agreements, including data protection and privacy requirements.

  • Access Control:

Implement robust access control mechanisms to ensure that only authorized individuals or systems can access cloud resources and data.

  • Data Classification and Handling:

Classify data based on sensitivity and define appropriate handling and storage requirements for each classification.

  • Encryption:

 Implement encryption mechanisms for data at rest and in transit. This includes using strong encryption algorithms and managing encryption keys securely.

  • Identity and Authentication:

Use strong authentication mechanisms to verify the identities of users and systems accessing cloud services. Implement multi-factor authentication (MFA) where applicable.

  • Incident Response:

Establish an incident response plan that outlines the steps to be taken in the event of a security incident. Ensure that cloud service providers have their own incident response procedures.

  • Audit Logging and Monitoring:

Implement comprehensive logging and monitoring of cloud resources and activities. Regularly review and analyze logs to detect and respond to security incidents.

  • Security Awareness and Training:

Provide security awareness and training programs for employees and users of cloud services to promote security best practices.

  • Vendor Security Assessment:

Assess the security practices of cloud service providers before entering into a contract. This includes evaluating their security controls, certifications, and compliance with ISO 27017.

  • Data Portability and Recovery:

Ensure that data can be easily transferred between different cloud providers and that there are mechanisms in place for data backup and recovery.

ISO 27017 provides a valuable framework for organizations using cloud services to enhance the security of their data and operations in the cloud. It’s important to note that organizations should adapt these controls to their specific cloud environments and risk profiles while also considering any additional industry-specific requirements and regulations. Additionally, it’s crucial to work closely with cloud service providers to ensure a shared responsibility model for security in the cloud.
