This book is to ISO27002 what ISO27002 is to ISO27001 - it is the guidance to the standard's guidance. As such, it is the most impressively comprehensive guide to implementing ISO27001-level InfoSec in your organisation. It gives detailed understanding and insight about the motivation and purpose of the different controls that will help build a fit-for-purpose ISMS. Because of this, I chose it as the set book for the very popular Open University Introduction to InfoSec module.
