Hi
Every server owner or site owner knows the attacks on the servers. Server protections are a tiring defense as well as a serious cost.
You can install the CSF Firewall Plugin plugin, which will allow you to increase your security and make optimization easier on your server with Directadmin installed, by applying the following command lines.
Remember to optimize after installing CSF.
Just follow the commands below in order.
cd /usr/src
wget https://download.configserver.com/csf.tgz
tar -xzf csf.tgz
cd csf
sh install.sh
