OpenSnitch is a Linux application firewall. It lets you create rules for which apps are granted access to the internet and which applications are blocked. Each time an application that does not have a rule in place tries to access the internet, a dialog box appears. This dialog box gives you the option to allow or block the connection.
It’s inspired by Little Snitch.
This is free and open source software.
