"PALADIN is a modified ?live? Linux distribution based on Ubuntu that simplifies various forensics tasks in a forensically sound manner via the PALADIN Toolbox. PALADIN is available in 64-bit and 32-bit versions." - www.sumuri.com
I've been teaching/issuing Paladin since it was released. It was good and now great. It is my go-to for acquisitions. Nothing is easier or faster. Ver 6 & 7 have a now user friendly triage tool that is super fast. I don't teach the bundled forensic tools included. They are all command line and not user friendly for entry level students. You can also use Paladin Edge, which has the same paladin toolbox for imaging and triage but does not have the bundled tools. Paladin also includes Autopsy which runs fine, but honestly, the Triage tool is much faster. There is no need for Autopsy on this distro. One of my fav features is the ability to convert full disk images to a .vmdk. It is very powerful in court to be able to launch the defendant's desktop in front of a jury.
