PURPOSE: A system for preventing DDoS(Distributed Denial of Service) by using triangulation and a method thereof are provided to block abnormal access by applying a white list and a threshold value to a first node. CONSTITUTION: A triangle expectation server(200) determines an initial access node as an attacker. The triangle expectation server is digitalized in a triangulation algorithm. The triangulation server includes collecting, maintaining, and calculating modules. The collecting, maintaining, and calculating modules maintain connection information of nodes. [Reference numerals] (100) Collect, maintain, calculate; (500) Connection information
