This gig is about doing the forensics of digital data / raw image file or physical disk portion and then summarizing whats happening. I use different open source tools to perform the digital forensics such as : 1. Sleuth Kit's Autopsy 2. EnCase Forensic Imager 3. Access Data FTK IMAGER
So if you want to do forensics of your system, server for tracking some activity or whether you have got a Computer Forensics assignment/assessment etc. contact me and I'll hopefully guide you.
