Abstract: The widely used P2P file share software has incurred a significant threat to the modern network security. A P2P file share monitor system is presented. The system employs the way of distributed protection, and security policy is set by managers collectively, but it performs at each network terminal, which avoids the problem of network performance bottlenecks and achieves fine-granularity access control.

Key words: peer-to-peer(P2P), file share, security monitor

摘要： 点对点(P2P)文件共享软件的广泛应用对现有的网络安全造成严重的影响。针对这些问题，该文设计了P2P文件共享监控系统。系统采用分布式防护的方法，安全策略由管理员集中定义，但安全策略的实施位于各个终端之上。与现有监控手段相比，避免了可能造成的性能瓶颈，具有更好的可扩展性，能实现更细的策略控制粒度。
