“It uses a heavily modified GNOME 3 desktop, and though it is
based on Ubuntu, a new installation of Linux Deepin 11.12.1 does
not have any of the network security applications that you find on
Ubuntu enabled: A default installation of Linux Deepin 11.12.1, the
latest edition, will leave your computer wide open for the bad guys
to mess with.“This tutorial shows how you can install IPTables, the Linux
firewall application, ufw, a command line frontend to IPTables, and
Gufw, a graphical interface for managing ufw, the Uncomplicated
Firewall, on Linux Deepin 11.12.1. The idea is to enhance the
network security profile of your Linux Deepin installation. Before
continuing, you might want to read why your computer needs a
firewall enabled.”
