H3C ARP攻击防御解决方案
当计算机连接正常，却无法打开页面；或许计算机网络呈现频频断线，同时网速变得十分慢，这些都可能是网络中存在ARP欺骗攻击所表现出来的网络景象。ARP欺骗攻击不仅会形成联网不稳定，引起用户无法上网，或许企业断网致使严重生产事故，并且使用ARP欺骗攻击可进一步施行中间人攻击，以此不合法获取到游戏、网银、文件服务等系统的帐号和口令，对被攻击者形成利益上的严重损失。因此ARP欺骗攻击是一种十分恶劣的网络攻击行为。ARP攻击现已对各行各业网络形成了无穷威胁，但一直没有得到有效的管理。连我们熟知的杀毒软件、防火墙都挡不住ARP欺骗攻击。主要因为ARP欺骗攻击的木马程序，通常会伪装成常用软件的一部分被下载并被激活，或许作为页面的一部分自动传送到浏览者的电脑上并被激活，或许通过U盘、移动硬盘等方法进入网络。因为木马程序的形状特征都在不断改变和升级，杀毒软件常常会失掉效果。(When the computer is connected normally, but the page cannot be opened; perhaps the computer network is frequently disconnected, and the network speed becomes very slow. These may be the network scene shown by the existence of ARP spoofing attacks in the network. ARP spoofing attacks will not only cause instability in the network, causing users to be unable to access the Internet, or may cause serious production accidents due to enterprise network disconnection, and using ARP spoofing attacks can further implement man-in-the-middle attacks, thereby illegally obtaining games, online banking, file services and other systems. The account number and password will cause serious loss of interests to the victim. Therefore, ARP spoofing attack is a very bad network attack behavior. ARP attacks now pose an infinite threat to networks of all walks of life, but they have not been effectively managed. Even the well-known antivirus software and firewalls cannot stop ARP spoofing attacks. Trojans mainly due to ARP spoofing attacks are usually downloaded and activated by disguising as part of common software, or automatically transmitted to the browser's computer as part of the page and activated, or entered through U disk, mobile hard disk, etc. network. Because the shape and characteristics of Trojan programs are constantly changing and upgrading, antivirus software often loses its effectiveness.)
