Re: Laptop Security DeepFreeze

[Gavin S <s7726 () yahoo com>]

My school uses deepfreeze to keep the students from
screwing up the machines. At every reboot the whole
system is reset, with the exception of the thaw drive.
Any update aplied to the system are lost. the only way
to install an update would be to turn off deepfreeze
temporarily, install the update and then turn it back
on. You could even allow the user to do this, assuming
you trust them that much, because the system uses One
Time Passwords using a combination of tokens to
generate a password that is good for one use. The
system works pret well and i can tell you from some
time spent it is difficult is not impossible to get
dissabled without the use of some other sort of boot
media such as a linux live disk with NTFS ebabled. 

Hope this helps

Gavin S.
