Statistics on Botnet-Assisted DDoS Attacks in Q1 2015. In Proceedings of the 6th ACM SIGCOMM Conference on Internet Measurement, Rio de Janeiro, Brazil, 25–27 October 2006 pp. A multifaceted approach to understanding the botnet phenomenon. The authors declare no conflict of interest. Additionally, because the only job TRAP needs to do is to complete three way handshakes with clients, TRAP can handle a request quickly and can recover quickly after it crashes. Since the target of the attacked host is our TRAP, not the service server, the service server will not crash. Then the user connects to the service server directly through IP translation without the need to connect to the service server through TRAP. First, only after a normal user completes a three-way handshake with our TRAP server, our TRAP server will dynamically notify the user of the IP of the service server. TRAP wants to solve the first problem and mitigate the second problem.

Second, the attacked service server may no longer be able to provide service to any client. First, the attacked service server may crash. When a DoS/DDoS attack occurs, the following results usually appear on the attached system. In this paper, we propose a TCP three-way handshaking server, called TRAP hereafter, which utilizes the options field in the TCP headers to redirect legitimate client traffic to the real service server to handle the DoS/DDoS attacks.
