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

    No - If you are aware which programs open incoming ports. E.g. check with netstat -tulpe

    Yes - If you want to make sure e.g. TCP port 22 or a webserver on 443 etc is only available from IP/Adapter xy. Or if you want to mess with filtering outgoing connections.
