基于P2P网络捕包与过滤的实现

Implementation of packet-capturing and filtering based on P2P network

P2P网络的出现使得计算机网络的安全性更加脆弱,使计算机更易受到外界不明用户的攻击,因此在网络中实现主动防御显得十分重要。网络中的主动防御是通过网络捕包及过滤来实现,这是一种有效的管理手段,可以进行流量监控、故障诊断以及观察到网络所受到的攻击。本文主要是在P2P网络模式中利用混杂模式具体编程实现底层数据捕包。

The emergence of peer-to-peer networks makes computer network security more vulnerable and it makes computers more vulnerable to outside-attacking from unknown users. In the network it is very important for us to take initiative defense. The active network defense is realized through the network packet-capturing and filter, which is an effective management tool. It can monitor flow, do fault diagnosis and observe attacks against the network. This paper mainly uses mixed mode programming to realize arresting bottom data packets in the P2P network model.
