I have a high passion for network security and I am currently beginning college for network communications managment. Anyway, I would like to know where should I begin! I've been looking over the AO website and there seems to be so much info I feel overwhelmed. I would like to get my feet wet into the security of networks but I do not know where to start...other than "on my own network" (of course) but what can i start doing to secure it.

Thank You
