I am currently working on systems like IDS (Intrusion Detection Systems). The first thing we want to do is to create an architecture capable of capturing data packets accurately on big networks (at least 1Gbps) to : - test IDS with real traffic
- analyze the data captures with statistical tools Currently, most Security systems are tested in an artificial environment but real traffic imply noise traffic which can be considered as attacks by the security systems. Our main goal is to be able to create real datasets to improve Security systems by understanding the dynamic of normal networks traffic. Basically, I try to realize that but high speed networks can't be accurately captured, a lot of timestamp collisions happened or we want to be as precise as possible.
