“The advantage of BackTrack 5 (BT5) is that it offers a slew of
security and forensic tools on a live DVD, ready to use. It’s based
on Ubuntu Lucid (10.04 LTS) with Linux kernel 2.6.38 and some
patched WiFi drivers to allow injection attacks. You can download
the distribution in a GNOME or a KDE version, for 32-bit or 64-bit
x86 machines. It’s a live DVD ISO file, which you can burn to a DVD
or write to a USB stick. On the desktop of the live session,
there’s an installer icon if you want to install BackTrack
permanently. For the first time, the project also has an image for
ARM, which you can run on your smartphone or tablet to test the
security of a wireless network.”
