通过对Gnutella协议内容的概述、存在的安全问题的分析,对传统基于网络层的DDoS攻击的原理、类型和检测的分析描述,对Gnutella网络中的DDoS攻击和基于网络层的DDoS攻击的分析比较,针对基于Gnutella网络的DDoS攻击特性提出防范的研究方法。
This paper presented an investigation on DDoS attack in Gnutella by summarizing Gnutella protocol, analyzed subsistent security problem in it and describing principle, category and detection of the traditional DDoS attack on network layer. On the basis of comparison between DDoS attack in Gnutella network and DDoS attack on network laye, this paper proposed methods on resilience to the former one.
