Perhaps one of the most overly wordy text books I have ever had the misfortune to read. Considering that this is a set book for my university course, I suppose that it must have intrinsic value, and admittedly after trudging through it for hours on end, one does feel that their knowledge on security issues has increased. This is particularly in regards to key definitions, and the kind of specific, technical knowledge that essay markers love. This, however, comes at the cost of the text book being incredibly boring, and thus nigh on impossible to read while high. Therefore, this book is probably of use when cramming for exams, but is too dull to read for pleasure.
