METHOD TO PROTECT DDOS ATTACKS USING NETWORK INFORMATION

摘要

PURPOSE: A method for protecting a network from a DDoS attack is provided to efficiently and stably use national communication network resources. CONSTITUTION: A local server gets DDoS(Distributed Denial of Service) attacker information from an agent or other local servers(700). If the acquired DDoS attacker information exists within the access allowable information, the local server refuses the internet access of the corresponding node(710,720). The local server registers the DDoS attacker information in the access allowable information(730). The local server spreads the DDoS attacker information to other local servers(740).
