At school I am a computer technician and we may have a problem with certain student bypassing our security. There are several methods which we are aware of however due to other circumstances and evidence we had to rule them out. What other methods are the of cracking/bypassing foolproof. I am not asking how to only what methods can be used (ie: startup disks etc.) I will look into it and see what may have happened. Also over the summer we may be changing to another system as foolproof has been giving us compatibility problems, any suggestion, deepfreeze?
