Series: Advanced Firewall Configuration in WHM/cPanel
Denial of Service (DoS) and Distributed Denial of Service (DDoS) attacks are common threats that every publicly accessible web server faces. The purpose of such attacks, in the simplest terms, is to flood a server with connections, overloading it and preventing from accepting legitimate traffic.
In addition to being able to manage traffic from a specific country or a list of countries, CSF allows you to manage access by country to specific ports. This can be useful if you need to ensure that a particular service is available globally (such as your web server on port 80) but want to restrict international access to services such as WHM/cPanel, SSH, or FTP.
One of the most-requested features on cPanel servers is the ability to manage and filter traffic at a country level. With the ConfigServer Firewall (CSF) plugin in WebHost Manager, you can do exactly that.
