A couple of the forensics applications are bash scripts that must be run from a shell terminal, while the rest have graphical interfaces. There is, for example, AIR (Automated Image & Rescue), which is actually a graphical frontend for dd and dc3dd. dd id a file converter and copier, while dc3dd is dd enhanced with features for digital forensics – on-the-fly hashing, split output files, pattern writing, progress meter, and file verification. The main interface of AIR is shown below.

Another interesting application in CAINE 3 is Autopsy, a browser interface to the command-line tools available in The Sleuth Kit (TSK). TSK, designed for investigative analysis of disk images, is powerful stuff, and there is a version called Sleuth Kit Hadoop, which integrates TSK into a Hadoop cluster. It was initially funded by the US Army Intelligence Center of Excellence (USAICoE).

These applications may be accessed individually, or you can use a graphical application called Caine interface, which provides a single-hop interface for using the installed forensic applications. The next five screen shots show the windows of the Caine interface:

This is the main interface. Pressing Create Report prompts you for authentication.

Aside from the Caine interface, all the other applications are already in the repository of your favorite distribution, but the Caine interface just makes the distribution a lot easier to use for what it is designed for. So like BackTrack, CAINE is one of those distributions you might want to dual-boot with your regular distribution on an external drive or install in a virtual environment, if you are interested in digital forensics.
