ConfigServer Security and Firewall
This software suite is a popular and user friendly security add-on for your Linux server. You can use it with WHM to monitor and manage firewall rules and detect malicious activity.
To install it, run the following commands on your server (*as root)
cd /usr/srcrm -fv csf.tgzwget https://download.configserver.com/csf.tgztar -xzf csf.tgzcd csfsh install.sh
Test for the required iptables modules:
perl /usr/local/csf/bin/csftest.pl
Now to configure CSF, log in to the WHM interface and navigate to Home / Plugins / ConfigServer Security & Firewall.
We recommend you follow the instructions and read the documentation on their page here.
ConfigServer ModSecurity Control
ModSecurity is a web application firewall (WAF) that you can deploy to detect and prevent attacks before they reach your application. It is based on OWASP CRS, the dominant WAF rule set, that brings protection against various attacks.
You can control the policies either globally or per cPanel user, which is useful in situations with multiple accounts per server with different application requirements.
It's easy to install it as a free add-on to your server by following the specific documentation on the provider's page here.
Munin
This open-source network and infrastructure monitoring tool is a great addition to WHM. It can help you monitor your server's overall performance by allowing you to analyze resource usage.
It is easy to set up quickly by navigating to WHM / cPanel / Manage Plugins, find "Munin for cPanel", and click "Install Munin for cPanel".
These just a few examples of useful WHM add-ons that you can install within your WHM/cPanel account, to enhance the capabilities of this software and allow for even more control of the applications.
