If you wanted to use OWASP ModSecurity Ruleset instead of Comodo, you can use the following commands. You can set ModSecurity, ModSecurity Rules and OpenLitespeed Web Server options using the nf file directly located at /usr/local/directadmin/custombuild/nf or run the following commands. You can if you want install using the custombuild WebAdmin GUI in the DirectAdmin dashboard.įirst we need to ensure we have the all the necessary files updated in custombuild using the following command: cd /usr/local/directadmin/custombuild In order to install ModSecurity we will be using the command line custombuild scripts. However, if you didn’t want to use Comodo rules you can instead use the rules provided by OWASP. We have chosen to use the rules provided by Comodo as we have found they are most compatible with the majority of web applications. The Comodo ModSecurity rules will be configured to automatically fetch and install the new rules as soon as they become available.

In this guide we will show you how to install ModSecurity using Comodo Rules with OpenLitespeed. It provides protection from a range of attacks against web applications and allows for HTTP traffic monitoring, logging and real-time analysis.

ModSecurity is an open source, cross platform web application firewall (WAF) engine developed by Trustwave’s SpiderLabs.
