I've come across a friend's setup where he has secured his boot/system hard drive using Windows 7 Bitlocker using a key stored on a USB drive that he always leaves in the computer (with no startup PIN). If his PC was stolen how secure would it actually be?
We've discussed it at length as I'm pretty sure that it is the equivalent of locking your house but leaving the keys in the door. Do any of you know for a fact how secure this actually is? I'd also appreciate any articles or references that state the facts about this?
Any help greatly appreciated!
