The command "ufw enable" is used to enable the Uncomplicated Firewall (UFW) on a Linux system. UFW is a user-friendly front-end for managing firewall rules in Linux.

When you run the "ufw enable" command, it activates the firewall and starts enforcing the rules you have configured. This means that incoming and outgoing network traffic will be filtered according to the defined firewall rules.

Enabling UFW is important for ensuring the security of your system as it helps protect against unauthorized access and prevents certain types of network attacks. It allows you to control which network services are accessible from your system and which should be blocked.
