DDoS Attack Against Router with Border Gateway Protocol and Precaution

This paper uses Finite State Machine(FSM) to analyze Border Gateway Protocol(BGP),whose results show that the update mechanism of BGP routers has safe defects.A Distributed Denial of Service(DDoS) attack method is proposed for routers with BGP.According to the communication data of BGP routers,a test software named RouterTest is designed and implemented to simulate DDoS attacks on routers.Experimental results demonstrate the effectiveness of the attack.Corresponding precautions against the attacks are also proposed.
