Over the course of the summer of 2013, the ModSecurity team participated in Google's Summer of Code (GSoC) program through OWASP. We helped by mentoring Mihai Pitu who developed a port of ModSecurity for Java!
The main problem this project solves is that you will no longer have to front-end your Java app servers with a reverse proxy in order to gain ModSecurity protections! ModSecurity
standalone code uses JNI to hook into Java servers (Tomcat, Spring, Stuts, etc...) as a Servlet Filter. We need BETA testers to help us ensure that the code is working properly. Please see the steps below and send us feedback.
