This 'official' book is a pretty sad piece of work. It is riddled with typographical errors, poor grammar, and ambiguous text. 70% of the book is dated, 20% is opinion masquerading as fact, and 10% is plain wrong. (Example; the section in Cryptography that starts "Differential Cryptanalysis: Also called a side channel attack..." is just embarrassingly bad rubbish).
The 'example questions' are largely pot luck; some of these are a challenge to an experienced native language speaker and would be very difficult for an ESL student. In any event, they break one of the core principles of good multiple choice assessment, to test the student's knowledge of the topic, rather than their skill at interpreting ambiguous sentence construction. (Fortunately the actual CISSP questions, while far from perfect, are significantly better than the dross in this book).
That said, there are some good, well written chapters in this book; I particularly liked the chapters on Telco and Network Security, the legal chapter, and the last chapter on Physical Security. The chapter on Physical Security in particular was well structured, well explained and well edited; it's a shame the other chapters couldn't be brought up to the same standard.
Given the price of this book, and the 'official' nature of it (is it actually official?) it's a disappointing effort. It's verbose, fragmented, poorly edited, and most of all dated. There's a lot of material in here about stuff which was trendy in the 80s and 90s, and not much of anything past that; there's no serious discussion of cloud computing for example, or mobile computing, or social media. (Hint to the authors - there's more to software security than buffer overflows. No, really.)
As a final note, while the book covers a wide range of stuff, it didn't actually cover all the material on the exam... which is something of a shortcoming given its great length.
