Computer Forensics resources are provided on this page. I’m not currently on the forensics side, but I will post things as I run into them.
Forensics Wiki is a great free resource for computer forensics. If you need to know where a specific web browser stores it’s history data so you can parse it, or are looking for an open source forensic tool it is a great place to start.
SANS has a forensic Linux distribution call SIFT, which is a great resource of free forensic tools.
