GTA/UFRJ has developed the RAT system, a new IP traceback system against denial-of-service (DoS) attacks. The RAT system uses a new technique based on a data structure called Generalized Bloom Filter in order to trace IP packets back to its true source [
1]. The system was deployed in the Linux kernel and installed in personal computers working as routers. Experimental results show that the RAT system can trace in less than one second the real source of a single IP packet without any storage in the network infrastructure [
2]. This guide shows how to install, configure and use the RAT system.
