A firewall is a network security system that monitors and controls incoming and outgoing network traffic. It examines each packet and determines whether to allow or block it based on a set of predefined rules. Meanwhile, Simplewall is a free and open-source software that serves as a lightweight personal firewall.

Benefits of Having a Firewall

• Protection against unauthorized access to your network.

• Increased privacy by blocking unnecessary traffic.
