A novel approach in securing DDoS attack

The DDoS attack is one of the existing security problems of online service. The current defense mechanism is very weak, because of the inherent TCP/IP protocol problems. This paper focuses on the overload protection mechanism for Router. We use the physical topology to do the simulation and propose the Bypass Guardian System (BGS) that can prevent the Distributed Denial of Service (DDoS) attack. This system can detect attack traffic and then redirect the traffic to the system itself. At the same time, the BGS can also monitor the traffic, filtering redirection, and proxy server.
