OpenRASP is a free and open-source Runtime Application Self-Protection (RASP) solution developed by Baidu Security, designed to safeguard web applications from increasingly sophisticated attacks. Unlike traditional protection methods that rely on request characteristics, OpenRASP integrates the protection engine directly within the application, ensuring accurate detection of vulnerabilities such as code injection and deserialization attacks without external dependencies.

OpenRASP offers deep monitoring by hooking critical functions and observing application execution flows across multiple layers, including databases and network systems. Its unique zero-rule detection capabilities allow for real-time identification of threats based on user input semantics and application context.

This solution supports a variety of application servers, including Tomcat, JBoss, and WebSphere, with plans to extend compatibility to languages like C#, Node.js, and Python. OpenRASP is customizable, thanks to its JavaScript plugin architecture, which enables developers to create tailored security rules and integrate seamlessly with existing SIEM systems. Through its community-driven approach, OpenRASP continuously evolves, providing robust security solutions for businesses worldwide.
