ConfigServer Firewall (or CSF) is a free and advanced firewall available for most Linux distributions. In addition to the basic functionality of a firewall – filtering packets – CSF includes other security features, such as login/intrusion/flood detections. CSF also includes UI integration for cPanel, DirectAdmin, and Webmin.
Installing ConfigServer Firewall (CSF)
To install CSF onto your Linux distribution, just follow these 5 easy steps:
First, in order to install CSF, you must log in to your server with root user

The downloaded file is a compressed form of a tar package, and has to be uncompressed and extracted before it can be used. To extract the file, use the following command and hit enter.
tar -xzf csf.tgz
Now it is time to execute the CSF’s installer script. Move to the csf directory (by using: cd csf) and execute the following installation script:
