First off, I have read most chapters of this book, but skimmed the rest, best I could do really. I have been practicing information security architecture and implementation for 10 years. I really liked the in-depth coverage of information security in general. The mapping of the Zachman Framework cells to the so-called SABSA framework is also impressive, but is simple enough to not warrant a whole chapter to be honest. But what is evident to me might not be so to the novice so I take nothing away from the author here.
However, I am very disappointed with this book from an application of methods standpoint. I was expecting so much more.
At the very least I expected some 'real-world' scenarios to be covered in some detail so the practitioner can use material, techniques presented in the book on the job. In several places, this book comes close to revealing the application of methodology being propounded under the trade name of SABSA but then fails to do so. Time and again, I turned over to the next page in anticipation but was left disappointed and exasperated! The author simply refers the reader to contact him for further details- well that's the point of reading the book isn't it? I bought this book for the details but left with an imitation of the Zachman Framework, which by the way is still more directly applicable to information security than SABSA in my most humble opinion. If I am wrong in having said that, it is because I did not learn how or why based on my reading of this book.
