I have to say I'm not so familiar with Linux security, but how about this scenario:Fred wrote:Decemberdoom has a good suggestion. I have used TrueCrypt before and have been happy with it. In Linux you can't currently encrypt the system partition however. This isn't a big problem with Linux as it would be in Windows. Data is scattered all over the Windows partition. In Linux you should have no data in the OS proper anyway, so it is easy to encrypt the data partition or partitions and still be safe. There is nothing in the OS itself worth protecting. OSs are a dime-a-dozen.
If someone has physical access to your computer when you're away, isn't it possible he could install a keylogger to your Linux OS and grab the passwords to your encypted partions/containers when you open them? Then next time when you're away, copy the encypted files or grab the whole computer..
I think the lack of easy(-on-install) full disk/OS encryption in Linux distributions has kept many chronic Windows users from migrating to Linux. Some bigger distributions are already offering this option on install, so why not Mint?
