exposure to bootable Linux distros

[Chris Halverson <chris.halverson () encana com>]

Has anyone had exposure to Operator (built from Knoppix) or PHLAX?  I haven't been able to download and try them but it 
was brought up in one of my classes that I am taking.

What purposes do you pentest with these?  
External perimeter security, DMZ or internal?  
How would you block non-authorized users from utilizing these? (with the exception of BIOS password protection and 
disabling the floppy, usb and cdrom boot capabilities)
