OpenRASP is a runtime application self-protection (RASP) solution that integrates directly into application servers through instrumentation to provide real-time security monitoring and protection. The tool monitors various application events including database queries, file operations, and network requests by hooking into sensitive functions within the application runtime environment. This approach allows OpenRASP to examine inputs with full application context, enabling more accurate threat detection with reduced false positives. When suspicious activity is detected, OpenRASP can block malicious requests in real-time while logging detailed stack traces for forensic analysis. The context-aware monitoring approach makes it resistant to protocol manipulation attacks that might bypass traditional perimeter security solutions. OpenRASP supports multiple web application servers and is designed for deployment on Linux platforms. The instrumentation-based architecture provides visibility into application behavior that external security tools cannot achieve, making it suitable for protecting web applications against runtime attacks including injection attempts and other application-layer threats.
