I personally liked the chapter about physical security. I have not heard about some of the ideas described there and I must say its quite interesting. I am happy I kept on reading so far as this part was quite cool.

Authors describe what are the high level factors of physical security. They describe how different types of physical security elements work for example keys, magnetic cards, chip cards, as well as construction elements. Its even hard to describe but I really liked that chapter.

Network security on the other hand is very poor. There is no clear structure and methodology of describing the information. Book jumps from topic to topic. Again there are things described that every IT specialists should already know so you often feel like at second year of college.

Also I can not figure out who comes up with the order of sub chapters. Many parts of the book seem to be just randomly appearing one after another. I just do not like the chaos and notorious wordy-ness. Too little content, irrelevant information, anecdotes and silly comparisons.

This book has almost nothing to do with security. If you count how many pages are covered with the “generic high level computing science tutorial” and how many are just a filler you have almost nothing left. Who wrote this book? Why is it 1200 pages long when it has maybe 300 pages of real relevant content?

All in all at least one of the two chapters was interesting so I would give this part 7.5 out of 10 points.

Final score 7.5/10
