When running any online hosting service a software firewall is key to help protecting your server(s) from being attacked if the hardware firewall fails to stop the attack.

With all our Linux services we recommend ConfigServer Security & Firewall which is a free software based firewall program. It also has an integrated cPanel addon which gets automatically added to cPanel once the installer is complete.

How to install

Installation is pretty simple and easily done with any SSH program such as Putty or Mac terminal (with SSH connection). Just run each line below to install the software:

[highlight]rm -fv csf.tgz
wget http://www.configserver.com/free/csf.tgz
tar -xzf csf.tgz
cd csf
sh install.sh[/highlight]

Next, it is a good idea to test whether you have the required IPTables modules setup:

[highlight]perl /etc/csf/csftest.pl[/highlight]

That is it, very easy install and works great with cPanel. If you have cPanel installed on your server just login to your WHM control panel and scroll to the bottom of the left hand side navigation to see the Firewall control panel. Make sure to change the setting from TEST to LIVE within the configuration screen.
