OpenSnitch is a GNU/Linux port of the Little Snitch application firewall.

How Does It Work:
OpenSnitch is an application level firewall, meaning then while running, it will detect and alert the user for every outgoing connection applications he’s running are creating. This can be extremely effective to detect and block unwanted connections on your system that might be caused by a security breach, causing data exfiltration to be much harder for an attacker.
