In today’s digital landscape, organizations increasingly depend on cloud computing for storing and managing personal data. While the cloud offers flexibility and scalability, it also introduces unique privacy and security challenges. To address these concerns, the ISO/IEC 27018:2025 standard provides comprehensive guidelines for protecting personally identifiable information (PII) in public cloud environments.
What is ISO/IEC 27018:2025?
ISO/IEC 27018:2025 is the latest international standard focused on the protection of personal data in cloud computing. It provides practical guidance for cloud service providers who process PII on behalf of their customers. The standard builds upon ISO/IEC 27001 (Information Security Management System) and ISO/IEC 27002, offering cloud-specific controls to enhance privacy and data protection.
Essentially, it ensures that cloud providers adopt transparent, secure, and accountable practices when handling customer data. Whether you are a cloud service provider or a client using public cloud services, ISO/IEC 27018:2025 helps you maintain trust and compliance in an evolving regulatory landscape.
Objectives of ISO/IEC 27018:2025
The main aim of ISO/IEC 27018:2025 is to provide a framework that helps organizations protect PII in the cloud while maintaining compliance with international privacy laws. The standard focuses on:
-
Transparency: Ensuring cloud users understand how their data is collected, processed, and stored.
-
Accountability: Defining clear responsibilities between cloud service providers and customers.
-
Data Protection: Implementing technical and organizational measures to secure PII against loss, theft, or misuse.
-
Regulatory Compliance: Aligning with global privacy regulations such as GDPR and other national data protection laws.
-
Customer Confidence: Building trust through consistent and verifiable data-handling practices.
