随着计算机网络技术的飞速发展,其应用范围也越来越广,为人们的生产生活提供了很大的方便。但同时也产生了很多网络安全问题,尤其是以ARP为主的攻击技术,其隐蔽性和破坏率是相当之高,经常有将重要的文件或数据造成丢失的现象发生。因此网络安全部门必须开发相应的防御系统,彻底将这种常见的网络攻击技术抵消在萌芽中。本文也会对计算机网络系统防ARP攻击的构建做进一步的探讨和阐述。 With the rapid development of computer network technology, its application is also more and more widely, which provides a great convenience for people’s production and life. However, many network security problems have also arisen at the same time. In particular, the ARP-based attack technology is quite high in concealment and destruction rate, and often causes the loss of important documents or data. Therefore, the network security department must develop the appropriate defense system, thoroughly offsetting this common network attack technology in its infancy. This article will also discuss and elaborate on the construction of anti-ARP attack on computer network system.
