计算机局域网ARP病毒攻击机理及防护方法

ARP病毒是一种特殊病毒,它利用了网络缺陷实施对网络的攻击,一般的杀毒软件和防火墙很难起到防护作用。防止ARP病毒攻击,应以预防为主,迅速查杀为辅。IP/MAC地址静态绑定、软件硬件结合防护是预防ARP病毒攻击的主要手段;一旦发生ARP病毒攻击,通过查找在网络中重复出现的MAC地址,可迅速发现攻击源,及时用专杀工具进行查杀可达到迅速处理ARP病毒攻击的目的。

Attack Mechanism and Protection Method of ARP Virus in Computer LAN

ARP virus is one kind of special viruses. It attacks the network by taking advantage of the network defects. Normal anti--virus software and firewalls can hardly play a role in defending this attack. We should mainly take precautions to prevent the ARP virus attack, assisting by virus scanning. IP/MAC--address static binding and the defense combined with software and hardware defending are the chief means of preventing ARP virus attack. So once there is ARP virus attack, we can find its source through searching the MAC addresses continually recurring in the network and use the specific virus removal tools to scan and clean the viruses, thus dealing with ARP virus attack instantly.
