I’m a little behind the curve here, as the final build was posted on the 11th of January. Oh well. For the security conscious administrator, the backtrack suite makes a great tool. If you don’t know what it is, or taken the time to at least check it out, cut some time out to do so soon. It will open your eyes a bit, I promise :)
The final build, available in either .ISO or VM-ware forms, can be downloaded from http://www.backtrack-linux.org/downloads/
If you can, use the torrent links. Your download will most likely be much faster.
