摘要：The Distributed Denial of Service (DDoS) attacks have not been around with any significance for very long over the history of ICT. However, this problem is evolving quickly, and it is becoming increasingly hard to grasp a global view of the problem. Particularly for Next Generation Network (NGN), that will provide advanced services, such as Quality of Service (QoS) guarantees to users and their applications. In this paper, we focus to analysis challenges DDoS prevention in NGN and propose a defense method using private security policy. The efficiency of our proposed method was also proved in the experiment with NS2. DDoS attack is controlled effectively by the private security policy the bandwidth of the regular traffic would be maintained
