P2P系统中非扫描型蠕虫研究

数以百万计的网络用户使用P2P网络来共享文件。但在P2P网络中,蠕虫则感染了大量的漏洞主机,并对信息设施和终端系统带来巨大的破坏。该文分析了P2P体系结构内在的风险,阐明了P2P蠕虫所带来的威胁,并且列举了威胁P2P网络的3种非扫描类型的螭虫:被动式蠕虫,反应式蠕虫和主动式蠕虫。鉴于这种情况,该文提出了一种能够减轻P2P蠕虫威胁的对策。

The Research of No-Scanning Worms in P2P System

Millions of Internet users are using peer-to-peer networks to share content files.But in Peer-to-Peer networks,worms can infect a large vulnerable population and inflict tremendous damages to information infrastructure and end systems.The paper analyzes inborn security risks in peer-to-peer model,and describes the dangers posed by P2P worms,then identifies three types of non-scanning worms that could leverage P2P network:passive worm,reactive worm and proactive worm.In view of this situation,we suggest one countermeasure which mitigates threats of P2P worms.
