I remember looking into vendor specific forensic certs such as Encase's EnCe and FTK's ACE but both had some prerequisites. I'm not sure when FTK's changed but apparently it's free and no prerequisites. On there website (/www.accessdata.com/aceProcess.html) It says "No Prerequisites, No Cost..." The process used to say (6) months of forensic work, a valid copy of FTK's products (which now you could just use demo's) and taken one of their prerequisite courses to receive your ACE. Of course, the catch is that you have to keep up the certification with taking a class after a year but for that first year you can still say you're ACE... just a heads up for anyone looking.
