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

      It’s not.

      If you have a house, it has a door which you can use to access everything inside.

      If you have a linux install with no services running on it, it has no doors, and thus doesn’t need any door locks. And if it does have services running on there (which run publicly), it now has doors, sure, but getting one of those doors open doesn’t guarantee access to the whole house - usually it’s gonna be an empty room

        Linux with no services? That’s not a usable system for anyone who would ask “do I need a firewall”

        Systemd is a service that runs logind. What are you doing without them?
