ModSecurity represents an open source firewall that can effectively help you guard your web applications against a range of different attacks, including SQL injection vulnerabilities and cross site scripting. The easiest route to installing this application is to contact your Dedicated Experts, but we’ll walk you through the process of how it works. First, there are a few things you should know about ModSecurity prior to installing it on your systems.

What You Should Know about ModSecurity

ModSecurity allows you to add and remove different security features that relate to the Apache server. By adding and removing different lines to the httpd.conf file, you can easily adjust the modules that correspond to various security functions. The most important thing to understand about this application is the fact that it helps you to increase or decrease the security level of any of your applications.

How to Install ModSecurity in CentOS

If you elect to independently install ModSecurity, the easiest way to install it yourself in CentOS is provided by Yellowdog Updater, Modified (YUM). However, in cases where YUM is not available in standard repositories, you can also find different tutorials that offer directions to install this program directly from the source. After adding the repository of your choice, you must accept the dependencies for your specific system. This is important if you wish to successfully complete the installation process. As soon as all of these applications are installed, ModSecurity is ready to run on the Apache server.

Basic Configurations That You Should Know

In some cases, you are not able to see any output of the file httpd.conf. However, you can add the output into the directory by simply introducing the particular configuration for ModSecurity. It is also essential to know that one of the most difficult aspects that relate to using ModSecurity leads users towards the IfModule section. This actually means that a part of the httpd.conf file presents some very complex features. The application delivers hundreds of options which are almost impossible to study. In order to get more information about these options, you can take a look at the available Configuration Directives on the ModSecurity website.

After checking the Configuration Directives, it should become clear that the complex features are some basic things of what ModSecurity actually does. Usually, these features are completing different functions, such as starting the system, setting default actions, scanning Payloads, checking valid values and more.
