You may wish to install a firewall to protect your computer against unauthorized access by people on the Internet or your network. Firewalls block connections to your computer from unknown sources, which helps to prevent security breaches. If you use a router to connect to the Internet, the router may already have a firewall configured which regulates connections from the Internet to your network. This section deals with setting up a firewall on Ubuntu to regulate connections to your computer.
