When it comes to securing the data I have on my computers, I take the task seriously. I use Ubuntu and Windows on my laptop. The Ubuntu installation is fully encrypted. There’s a performance hit but I feel pretty sure that if my laptop is ever stolen or lost or needs service by a third party, I won’t be at risk of getting sensitive information stolen. The Windows side is not (yet) encrypted but I do not use Windows intensively or for sensitive tasks so I’m not very worried about that.
Now, when I talk to other people about this, I’m told that I’m paranoid. If I’m not keeping porn on my laptop, I have nothing to worry about. If my laptop is stolen, no one will take time to look for banking information. The techs who perform service are interested searching for porn, not financial details. Basically, I’m told I’m worrying for nothing. (Now, logically-minded readers will have figured out that the flip side of this bad reasoning is that if I do worry about people snooping through my hard disk, then it means I must have porn on there.)
Well, well, it turns out that a Sky News undercover investigation that technicians do indeed look for financial information on the laptop they service and they try to use it to break into banking accounts. OMG! Who would have thunk?
The solution against unscrupulous technicians is to give them a clean drive: a drive which contains no sensitive information. My point here is not that encryption is the solution but that unscrupulous people are indeed after your financial information. Encryption is part of the arsenal of tools to protect against that.
