I currently have a fully encrypted Windows System, and I'm looking at switching to Ubuntu. Is encrypting my home directory (with ecryptfs) sufficient?
On windows this would be problematic due to software leaking out some possibly critical details, but on Linux I usually wouldn't have write permission to many places outside of my home directory anyways.. right?
The other issue is that I currently have a strong password (for "offline" attacks) for the system-level encryption, but a weak login password for the Windows user account, since I log on/off often (while leaving the PC running). This isn't an issue considering that windows limits how many failed logins you can try out per time interval. With ecryptfs however my login-password would also have to be strong since the ecryptfs password is derived from it. Is there perhaps a way to mount the home directory once after boot up, indepentently of my login password (and subsequently, does Linux/Ubuntu limit failed login/su attempts)?
