• How to Install ModSecurity 3 with Nginx on AlmaLinux 9

  ModSecurity, often referred to as Modsec, is a free, open-source web application firewall (WAF). ModSecurity was created as a module for the Apache HTTP Server. However, since its early days, the WAF has grown and now covers an array of HyperText Transfer Protocol request and response filtering capabilities for various platforms such as Microsoft IIS, Nginx, and Apache. ModSecurity’s primary role is to provide protection for web applications by filtering incoming traffic and blocking malicious requests. The WAF can also be configured to monitor traffic for certain types of activity, such as SQL injection attacks, and generate alerts when such activity is detected. In addition to its security benefits, ModSecurity can improve web performance by caching rules and eliminating the need to process the same request repeatedly.

  Along with Modsecurity installation, OWASP Core Rule Set (CRS) is commonly used in conjunction with an open-source set of rules written in ModSecurity’s SecRules language. The CRS is highly regarded in the security industry, and ModSecurity is considered one of the most effective ways to protect web applications from attack. While ModSecurity is not a silver bullet, it is an essential tool in the arsenal of any organization that takes web security seriously.
