by reading you posts i get it that you really are someone who is looking for the right thing and unlike most others you are looking for it at the right place

you get what i mean
any ways from what i have read and what i know u need to know and think like a cracker if u are up to securing your network. you need to know how cracking softwares work, how they work on your network what results they display. As by thinking how a cracker thinks you get to know a lot vulnarabilties in you network than you think like the network admin. but the difference between us and the crackers is that we do it the legal and ethical way.
