UFW is a user-friendly firewall solution that is easy to configure and manage. It is a terminal-based application that relies on the iptables firewall to provide a secure environment. UFW is pre-installed on Ubuntu systems but can also be installed on other Linux distributions. It has a simple syntax that makes it easy for beginners to use. UFW also has a graphical interface, gufw, which makes it even easier to manage.
