I've recently build my own Fedora Core ISP VM and pulled every trick out of the hat to secure it. I'm talking about a firewalled-safesquid on a bootable cd (YOU TRY AND PUT A ROOTKIT ON THAT YOUNG LADDY!!) for my ISP machine, bastille, tripwire, chkrootkit, portsentry, avast, alot of encryption stuff, alot of digest stuff, etc... if you even knew what all the above meant, you wouldn't want to be a hacker, so go toddle off and play with your imaginary friend, i'm so sick and tired of Hollywood-Indoctrinated-wannab-hackers, get real, or get CAUGHT!!! Rather spend your time on becoming a good info sec expert, or digital investigator (if you really really want to "hack"), these jobs pay EXTREMELY well, so get your act together, finish school and learn to become a successfull contributor to society.
