Ubuntu uses UFW (Uncomplicated Firewall) as its default firewall management tool. It is a user-friendly front-end for iptables and makes it easier to configure the firewall by providing a set of predefined rules. UFW can be used to allow or deny incoming and outgoing traffic based on IP address, port, and protocol.

UFW provides a simple command-line interface for managing iptables firewall rules. With UFW, you can configure your firewall rules to allow or deny traffic based on specific criteria such as IP addresses, ports, or protocols. The UFW commands are straightforward and easy to use, making it ideal for both novice and experienced users.

To get started, you first need to enable the firewall by typing “ufw enable” in the terminal.
