I believe every Unix/Linux user wants his/her own computer free from key loggers. And I believe this cannot be done without some kind of OS-level support. The idea is that keypresses are only sent to the process who is actively accepting user input, and users should be aware of the process identity. Does Unix/Linux already have such (or other kinds of) security features against key loggers?
Does Unix/Linux have any security features against key loggers?
