SESSION MAINTENANCE SYSTEM IN DDOS ATTACK

摘要

A session maintenance system in a DDoS (Distributed Deny of Service) attack can include a user terminal, a control server, an origin server, and a plurality of proxy servers. A session maintenance method can include the steps of: generating a plurality of sessions by connecting a plurality of proxy servers with each other and connecting the plurality of proxy servers with the origin server; setting a communication session with the origin server through a first proxy server; and resetting the session through one of the second to n-th proxy servers according to a request of the control server. The plurality of proxy servers can include first to n-th proxy servers.
