A firewall protects a computer system from unauthorized access. It is not normally necessary to install a firewall on a Kubuntu system, because by default, access to the system is closed. However, if you run any services which you allow other computers to access (for example, the Apache web server), it is advisable to install a firewall. Guarddog is a program which allows you to control Linux's firewall through a graphical interface.
