ARP攻击源的快速定位与过滤策略研究

ARP Attack Source Rapid Positioning and Filtering Policy Research

目前局域网内充斥着各种网络攻击，其中ARP攻击对局域网的安全稳定影响最为严重。若局域网中存在该类型的网络攻击，将导致局域网内的主机出现大面积掉线、个人重要信息被窃取等严重安全事故。本文对ARP协议及ARP攻击原理进行了详细分析，实现了在不借助任何网络分析工具的前提下快速定位ARP攻击源的方法，大大节省了定位与过滤ARP攻击源所需的时间，具有较强的实用性。

Nowadays the LAN is full of various network attacks,which ARP attack effects the security and stability most seriously.In case that there is ARP attack in the LAN,it could result in severe safety accidents such as large area network disconnect and the stealing of the user＇s important information.This article makes a detailed analysis of ARP protocol and attacking principle,finding a way of locating attack source promptly without any network analysis instruments.This method saves much time spent in locating and filtering ARP attack source to a great extent and has a strong practicability.
