Hi there. I'm soon to be receiving my BS in computer science, and I'm hoping to launch an interesting (and maybe even well-paying) career in InfoSec/network security.

So I have a question for the pros out there: how many jobs exist in which a security admin does not need to deal with Windoze? I really do not enjoy using Microsoft products (I've managed to rid my personal computing life of them,) and I'd like to stay as far away from Windows security as possible.

Is this going to put me at a disadvantage in the field? Can I specialize in UNIX-based OSes and still find jobs?
