Really good advices, Thanks...
Also I' going to read "Counter Hack: A Step-by-Step Guide to Computer Attacks and Effective Defenses", It seems good.
Real-Life examples are really great but most of them is not so exiting

Sessions will be long, I've enough time to do all of them.
Students are very good in programming area and they want to learn security. But I hope that they're good.
I'm planing to some scenarios;1. Man in the Middle Attack (sniffing SSL and Proxy)
2. Compiling a well known exploit and entering a Win / Linux box, Also after enter how they can go out, transferring files basic usage of netcat etc.
3. SQL Injections and Web Security (Small demonstration of exploiting complicated login forms, switching users), May after this session I can show them how can they manipulate queries dump all data, Union samples
4. Sniffing in switched enviroments, Filtering data that you want
I know that most of them is pretty generic, so I'm lo oking for more.
Thanks and replys are welcome
