Well, I first got interested when I was DoS'd after banning someone out of an IRC channel (many moons ago). The curiosity remained somewhat dormant until I began looking into network administration and discovered a book by Stephen Northcutt, Network Intrusion Detection: An Analyst's Handbook. I was in awe and intrigued about how much you can learn about a network and security by using something as simple as tcpdump. Around the same time I found AO and the school I was an admin at was introducing a security course. This meant I had to develop the necessary lab so the students could do the work they needed to do as well as learn some of the "toys".

After being an admin for a few years, it was suggested I get into teaching. I decided I wanted to specialize in security because it was just so cool (or so it seems to me). Every time I teach something or learn something that I can in turn pass on to students or friends in IT I feel like I've been part of an exploration or adventure.
