Show Suggested Answer

Suggested Answer: B

ISO/IEC 27018 is the ISO standard that provides guidance to ensure that cloud service providers offer appropriate information security controls to protect the privacy of their customer's clients by securing personally identifiable information entrusted to them. ISO/IEC 27018 is a code of practice for protecting personal information in cloud storage. The term for the personal data it covers is Personally Identifiable Information or PII. ISO/IEC 27018 is an addendum to ISO/IEC 27001, the first international code of practice for cloud privacy. It helps cloud service providers who process PII to assess risk and implement controls for protecting PII. ISO/IEC 27018 was created in 2014 and updated in 2019. It has the following objectives:

Help the public cloud service provider to comply with applicable obligations when acting as a PII processor, whether such obligations fall on the PII processor directly or through contract.

Enable the public cloud PII processor to be transparent in relevant matters so that cloud service customers can select well-governed cloud-based PII processing services.

Assist the cloud service customer and the public cloud PII processor in entering into a contractual agreement.

Provide cloud service customers with a mechanism for exercising audit and compliance rights and responsibilities in cases where individual cloud service customer audits of data hosted in a multiparty, virtualized server (cloud) environment can be impractical technically and can increase risks to those physical and logical network security controls in place123.

27001 is good, but 27018 is specifically for cloud privacy.

I’m a bit confused about ISO/IEC 27011 and 27007. I think 27011 relates to telecommunications, but I can't recall what 27007 covers.

I practiced a similar question, and I believe ISO/IEC 27001 is more about general information security management, not specifically for cloud services.
