ISO 27017 and ISO 27018: Cloud Security and the Protection of Personal Data

Cloud adoption has fundamentally reshaped how organizations manage security and data protection.

As environments become more distributed, responsibility becomes shared, and the need for clear control frameworks becomes critical.

In Episode 6 of Season 3 of The Virtual CISO (Compliance, Controls and Confidence), we examine ISO 27017 and ISO 27018 and how they extend ISO 27001 to address cloud security and the protection of personal data.

ISO 27017 provides guidance on cloud-specific security controls, clarifying responsibilities between cloud service providers and customers.

ISO 27018 focuses on protecting personally identifiable information (PII) in public cloud environments.

In this episode, we discuss:

• The purpose of ISO 27017 and its role in cloud security governance
• How shared responsibility is defined between provider and customer
• Key control considerations for securing cloud environments
• The focus of ISO 27018 on privacy and protection of personal data
• How organizations demonstrate accountability when processing PII in the cloud
• How these standards align with ISO 27001 to strengthen overall security posture

Cloud security and privacy are no longer separate conversations. They are part of a unified approach to building trust in modern digital environments.
