How To Use Firewall GUI In Ubuntu Linux

Published May 19, 2021

Firewall GUI

Linux is the best-known and most-used open-source operating system. As an operating system,

Linux is software that sits underneath all of the other software on a computer, receiving requests

from those programs and relaying these requests to the computer’s hardware.

A Linux distribution is a selection of coordinated software around the Linux kernel, which in some

cases is also a more or less adapted distribution kernel that is usually maintained in close

coordination with Upstream itself.

In computing, a firewall is a network security system that monitors and controls the incoming and

outgoing network traffic based on predetermined security rules. A firewall typically establishes a

barrier between a trusted network and an untrusted network, such as the Internet.
