PXE Booting

[one2 () onetwo com]

Hey pennies,

I performed an onsite pen test for a client who had network booting first in their BIOS boot order for their 
workstations. This was used to check for any updates that needed installing.

Therefore, as a demo, I setup a PXE server using CHAOS .. supercomputer for your wallet ;o) ... to force any system 
booting up to boot CHAOS and join my cluster - showing from there I theoretically had complete control of the 
underlying system.

My question is, what recommendations should I make to this client in relation to securing PXE booting? ... or any other 
useful suggestions that people feel like they have to make, like "Dont use PXE booting"! ;o)

Thanks,
One2
