局域网数据过滤设计方案

Local Network Data-filter

首先简要介绍防火墙技术和网络入侵检测技术,并针对目前常见蠕虫病毒对以太网类型的局域网所造成的危害进行分析,结合现有技术提出一种能阻止蠕虫病毒向外扩散的局域网数据过滤的设计方案.

The paper first introduces the firewall and NIDS（Network Intrusion Detection System）. After analysis the worm virus and its harm to the Ethemet type local network, we put forward a design of data-filter system to prevent worm virus spreading.
