It is a nice compilation of information about hacking. The first chapter is a definition and clarification of some different terms (hacker vs cracker etc.), and a look at the legal and moral issues. He then goes on to some laws of security in the second chapter. In the third he classifies the different attack methods. The next chapter deals with some methodologies. The next 4 chapters are about diffing, cryptography, unexpected input and buffer overflows. The third part (chapter 9 to 14) deals with remote attacks. These chapters deal with network sniffing, session hijacking, identity spoofing, server and client holes, viruses, trojan horses and worms. The last chapter is about reporting security problems and incident handling. It's a nice and not too technical book with some practical examples.   The TCP/IP Illustrated - Volume 1: The Protocols   The TCP/IP Illustrated - Volume 2: The Implementation Programming Perl The C Programming Language: ANSI C Version UNIX User's Handbook Essential System Administration Practical UNIX and Internet Security Java Network Programming Java Performance Tuning
