Abstract: The present invention relates to a system and a method for managing harmful traffic filtering information. More specifically, if an edge router of a second autonomous system (AS), which is positioned at the rear end, detects harmful traffic and sets up traffic filtering information, the edge router transmits the traffic filtering information to a first AS at the front end, from which the harmful traffic was transmitted, through a border gateway protocol (BGP), and then the corresponding first AS applies the received traffic filtering information to a related router. Therefore, harmful traffic can be blocked in advance at the front end from which the harmful traffic is transmitted.
