I have a Ubuntu desktop. I want to protect my installation from software which can steal passwords I enter by logging keystokes or capturing the screen in case of a graphical on screen keyboard. I am following the following steps:
1) Making sure I only install new software using the 'apt' command.
2) Enabling the ufw firewall to block incoming.
Are these steps enough? Can I be assured that there is no keylogger or screen capture software on my system? Or do I need to take additional precautions?
