I'm getting a chance to take the Security+ exam free of charge by my employer. Has anyone acquired this certification and have any insight on what to pay particular attention to to prepare for the exam? They kind of put me on the spot by giving me only a few days notice. I have 3 years in IT but my experience isn't focused mainly on securing systems...more on solving network/general hardware problems. Given my background, what subjects should I do some cramming on to prepare for the security+ exam? I'm thinking encryption techniques is a big one.....what others should I study up on?
