小型局域网安全防护研究

Research on Small Local Area Network Security Protection

局域网是指在一定区域之内通过路由设备将区域内的计算机连接起来,可以相互访问的计算机群组。在局域网中,由于网络具有共享性,局域网中只要一台计算机感染病毒或者木马就会迅速传播到局域网中的其他电脑之中。局域网安全已成为各企事业单位不容忽视的一个问题。

A LAN is a computer group that connects computers in a region through a routing device and can access each other.In the local area network(LAN),as a result of the existence of a network share,once one of computers in the LAN infected virus or Trojan,it will soon spread to other computers in the LAN.LAN security has become an issue of all enterprises and institutions that should not be ignored.
