From the site
"Knoppix-STD is a customized distribution of the Knoppix Live Linux CD. Boot to the CD and you have Knoppix-STD. That would include Linux kernel 2.4.20, KDE 3.1, incredible hardware detection and hundreds of applications. Boot without the CD and you return to your original operating system. Aside from borrowing power, peripherals and some RAM, Knoppix-STD doesn't touch the host computer.
STD focuses on information security and network management tools. It is meant to be used by both the novice looking to learn more about information security and the security professional looking for another swiss army knife for their tool kit.
The tools are divided into the following categories (see the STD Tools section for details):
authentication
encryption utilities
firewalls
penetration tools
vulnerability assessment
forensic tools
honeypots
intrusion detection
packet sniffers and assemblers
network utilities
wireless tools
password auditing (crackers)
servers"
Perfect for anyone not familiar with linux but would like to try it out while testing out their wireless network. Note that not all wireless cards will work with this
