It is responsible for monitoring both incoming and outgoing traffic to ensure that everything is safe. When a computer is connected to the internet, it will have three different active ports. They are incoming port, outgoing port and an email port. In most case scenarios, all three of them will not be active which is when malicious codes and programs online will try to establish a connection with the server. If the access is granted they will instantly install themselves into the PC and try to exploit the registry or the operating system. The firewall security gets rid of such pesky malware and trojans by blocking them at an early stage.
