This book is a very interesting read and would recommend any CSO to read it. I've been to too many seminars where opions and products are the driving force of selling a product. This book gives an objective view and I have found it helpful in my own evaluations and have given me food for thought. The CD with the book gives some useful information and links to some very good articles, and tools.
I am designing one of the largest networks and security infrastructures in the world, and thought generating books even though they may not give you the complete answer wrangle your curiousity and indepth knowledge of others.
This will book can only expand on what you know or you don't know. Recommended
