Test your environment's security with BackTrack
In the field of penetration testing, BackTrack is today's premier Linux distribution. Designed for, created by, and used by security professionals around the globe, BackTrack is the result of a merger between two earlier, competing distributions -- WHAX and Auditor Security Collection. The most recent beta version was released on June 10.
BackTrack 3.0 beta (BT3) is showing up in a lot of places these days. There was a presentation in February at ShmooCon, an annual hacker convention. At this year's National Collegiate Cyber Defense Competition (NCCDC), it was the distro of choice for the Red Team -- the attackers -- made up of experienced security professionals.
BT3 live or installed
BT3 is distributed as an ISO image for a live CD or as a larger USB drive version in RAR format. You can grab the image online from any of several mirrors, then either burn a bootable CD or install it on a bootable USB drive.
