Hacker's Challenge 2: the second volume in a series of books that present a series of real-world security scenarios and their solutions. For each scenario, information is given, clues are presented and questions are asked of the reader. Turning to the back of the book reveals what really happened along with suggestions and tips for how to respond to and possibly even prevent each presented attack... The solutions are well presented and thorough, covering not just what happened in the attack and how to put the course of events together from the clues, but also ways to prevent and mitigate the attacks. Highly recommended.
