Query: Overrated book

I sympathise with the opinions of many of the more critical reviewers. The book is for non-technical people. It does introduce a number of areas of importance to security professionals, but far too superficially. The depth of coverage is admittedly deeper than a newspaper or newsmagazine piece on the subject, but it's not much deeper. The style is a bit too sensational. The organisation of the book could do with an overhaul - the author tends to drift off into examples of dubious relevance. The book in general could do with a tighter and more stream-lined organisation.The book isn't devoid of merit and people wishing to learn about the area could do worse than start here. For myself, I'm waiting for Ross Anderson's new book titled, "Security Engineering".
