Network management apparatus and method thereof, user terminal for managing network and recoding medium thereof

The present invention relates to a network management apparatus and method. The network management device of the present invention harmful traffic information from a plurality of user terminals - of the storage to receive, respectively, and harmful traffic information stored - where harmful traffic information comprises a source IP address and destination IP address of the malicious traffic claim detects malicious traffic information having a first destination IP address. And harmful having a exceeds the number of the judgment to the detected malicious traffic information whether or not set if the detected malicious traffic information exceeds a predetermined number, the first destination IP address as the transmitting the detected malicious traffic information user terminal and it transmits the generated control message for traffic transmission block. According to the invention, which may block the inherently a plurality of transmission terminals attack on a target device such as a DDOS, to delete the program for generating the traffic and reduce the load on the user terminal, a user terminal used in a malicious attack the effect to prevent that can be expected. Traffic, attacks, hacking, cracking, DDOS, management, network
