Thanks very much for the welcomes!
I've found that if you know where to look for information, ignorance doesn't matter as much.
Absolutely, I always find that if I don't know about something, then a web search can usually turn up some basic information which tends to be a good starting point to explore the subject further.
Are you currently pursuing anything in the forensics realm? Any ideas of what you may target?
Well, I'm looking at CHFI as a possibilty. I'm particularly interested in the incident response (breaches etc) side of forensics but data recovery is also appealing to me. I have just started playing around with Helix on a USB stick and getting a feel for whats possible with it.
I guess that as I gain more experience, I'll work out where in the security field I most want to be.
