Now-Closed KDE Vulnerabilities Remind Us X11 Screen Locks / Screensavers Are Insecure

[TheBlackCat]

You should have a lock on the door. Computers can't be trusted. If someone has access to your room, he can also physically disassemble your computer and read data.

It is a lot easier to do a few mouse clicks without getting caught than disassembling a computer.

Instead of lock screens log out. It's a standard feature since novel netware etc.

That is great, I will just cancel my 8-hour simulation runs whenever I go to the bathroom. Brilliant plan there.

I like how this handled on Windows: Hibernate and in addition to screen lock your disk encryption also locks up so you have to enter two passwords to access the machine. User data is typically encrypted behind a second layer of encryption which uses user password

If someone has physical access to your machine, he can install a a cheap *physical* USB key logger on between your keyboard and your computer and he owns your ass.

Mind you, I do agree that a working (Ugh) screen saver lock, hibernation and disk encryption go a long way to improve the security of your machine, but even this is far from being enough.
