BackTrack
BackTrack is the result of merging the two innovative penetration testing live linux distributions Auditor and Whax. Backtrack provides a thorough pentesting environment which is bootable via CD, USB or the network (PXE). The tools are arranged in an intuitive manner, and cover most of the attack vectors. Complex environments are simplified, such as automatic Kismet configuration, one click Snort setup, precompiled Metasploit lorcon modules, etc. BackTrack has been dubbed the #1 Security Live CD by Insecure.org, and #36 overall.
New exciting features in BackTrack 2, to mention a few:
* Updated Kernel-Running 2.6.20, with several patches.
* Broadcom based wireless card support
* Most wireless drivers are built to support raw packet injection
* Metasploit2 and Metasploit3 framework integration
* Alignment to open standards and frameworks like ISSAF and OSSTMM
* Redesigned menu structure to assist the novice as well as the pro
* Japanese input support-reading and writing in Hiragana / Katakana / Kanji.
