Hi. I wanted to know if it’s needed to install a firewall on a linux desktop/laptop. Why yes or why no?

    Any vulnerabilities in any of your software that can talk to a network, ssh, browser, the operating system itsself could be exploited if your firewall is down

    If you’re using username and password and have ssh enabled, for example anyone on your network could attempt to log in to your machine

        My understanding is there can be a vulnerability in absolutely anything

        Browsers are unlikely to but don’t think it’s impossible

          A firewall protects open ports on your machine. A browser does not have any open ports.

          Of course they have vulnerabilities, but a firewall won’t protect you from them.
