Security in Computing review

A review of the 4th edition of Security in Computing by Charels P. Pfleeger and Shari Lawrence Pfleeger can be found at http://www.unixreview.com/documents/s=10104/ur0611m/ur0611m.htm. There are two broad categories of security books: 1) those that focus on one small topic/solution and the implementation of it, and 2) those that provide an overview of all aspects of computer security. The fourth edition of Security in Computing falls into the latter category, and I must honestly say there isn't a more complete and up-to-date title filling this niche that I am aware of.
