Readers generally appreciate this book for serving as a great introduction to information security concepts. It is noted for its overall quality in presenting these foundational ideas, making it a valuable starting point for those new to the subject.

However, some readers felt the book did not significantly expand their existing knowledge, offering little new information to those seeking deeper insights or comprehensive coverage. Additionally, a specific criticism points to the content being somewhat heavy on physical security aspects, which might not align with every reader's expectations for a general infosec overview.

In conclusion, the book appears to be a valuable resource for individuals new to the field of information security, providing an accessible starting point for key concepts. It would likely appeal most to beginners or those specifically interested in the physical dimensions of security, rather than experienced professionals or readers looking for comprehensive, in-depth coverage across all infosec domains.
