1 stars (not a good reference manual..or book on computer security) - In a course, this book was used as teaching material in a class for computer security. The read, reminded me of speaking software to a hardware engineer. Since the hardware engineer is coming from another level, the experience was like talking DOWN to the reader. The author seemed to want to "impress" us with his "knowledge". Luckily, we were fortunate to have an instructor that could translate for the class. Had to use other manuals to replace what the author, may have tried to relay. 1 stars (La la la la) - Unless you are already an expert at security and are looking for a strictly abstract approach, save your money!! Ramachandran's ramblings go on forever, with little imparted to the reader. The best comparison I can come up with for the experience of reading this book is that it's the same as trying to learn a foreign language from a mime. If Ramachandran spent less time trying to impress us with a bibliography that goes on for pages [I don't really CARE if he has read every security book in the world, if he can't distill this information down and pass it on the text is worthless] and more time on organizing his book [for heaven's sake, is a decent index at the back too much to ask?] then it may be usable, as it is, the only thing to do with it is level a table. 5 stars (Layered approach to multi-level security) - This is one of the most pragmatic, thorough books on security architectures I've read. The approach the author takes represents best practices in a number of disciplines, including architecture, software engineering, and infrastructure management. This holistic view of security architecture is not provided in total in any of the hundreds of security books I've read. Among the reasons I like and recommend this book are: the approach starts with architectural principles and a survey of approaches based on well known models, as well as development life cycles in the real world. ...
