The security of private information has never been more important. Many national and international organizations, including the International Organization for Standardization (ISO), the United States government, and the European Union, are working to solve this issue. The international standard ISO/IEC 27018 is one project they have in common. ISO/IEC 27018 is a best practice guide for safeguarding personally identifiable information in public cloud services. It is designed as a supplement to the widely used and recognized ISO/IEC 27002 code of practice for information security measures.

ISO/IEC 27018, an extension of ISO/IEC 27001 and ISO/IEC 27002, gives recommendations to companies concerned about how their cloud providers operate. are entrusted with personally identifiable information (PII).

ISO/IEC 27018 assures that a cloud service provider has adequate PII handling processes in place. It can also aid in the creation of more robust cloud service agreements. The standard specifies how CSPs can educate their employees about PII, as well as the documentation methods that must be observed and the principles that must be followed. ISO/IEC 27018 strives to provide true transparency for cloud service customers, so that they have a clear knowledge of what the cloud service provider is doing in terms of personal data security and protection.
