The information in this article is related to VPS or Dedicated servers only.

CSF’s homepage describes it as ‘A Stateful Packet Inspection (SPI) firewall, Login/Intrusion Detection and Security application for Linux servers.’  That’s great, but what does that mean?  What that means is that CSF simplifies managing your server’s base firewall settings.  This includes blocking and permitting IP addresses, and restricting access by port number.  But CSF has extra security features, too.

Ok, What Are The Advantages of CSF?

Managing firewall settings ‘by hand’ with the iptables command in Linux can get complicated.  Also, the active rules for iptables are not persistent.  This makes it is easy to understand why there are several firewall ‘managers’ available.  So if CSF is not unique in providing basic iptables rule management, why use it?  What helps set it apart from similar applications are its additional built-in features.  Just a few of these are:

  • The ability to perform a basic security, stability, and settings check on your server
  • The Login Failure Daemon( LFD ) helps protect your server against brute-force login attempts
  • Watching, and searching various important system log files right from WHM
  • Viewing currently 'listening' ports, and the processes that listen on them
  • And lots more

Great!  How Do I Get It?

Our VPS, and dedicated servers start with Advanced Policy Firewall( APF ) installed.  If you wish to switch over to CSF instead, and you have root access you can install CSF yourself. If you don't have root access, feel free to contact our Support team.
