【摘要】 IP 地址盗用是网络管理中常见且危害极大的因素。IP 地址盗用不仅给网络计费带来了负面影响,而且破坏了正常的网络运行和应用,因此解决IP 地址盗用问题是保证校园网安全运行、追查和防止来自校园网内部的网络攻击事件的首要条件。本论文以解决IP 地址盗用问题为出发点,在掌握了IP 地址盗用原理的基础上,仔细分析了现有的IP 防盗二元模型和三元模型的缺陷,以及基于ARP 的防盗方案的缺陷;在深入研究SNMP 协议之后,针对我校校园网的网络结构,提出了用户注册和交换机控制相结合的一种基于SNMP 的四元模型的新防盗技术,并在WINDOWS环境下采用语言编程实现了基于B/S 结构的、具有监测、定位、报警、阻断网络通信功能的防盗系统。从而非常有效的防止了校园网上的IP 地址盗用。更多还原

【Abstract】 IP address embezzlement is a common and very harmful factor in network management .It not only brings the negative effects to the network charging but also destroys normal network operation and application. Consequently the solution of IP address embezzlement is the most important condition to guarantee the safe operation of campus network and trace or prevent attacks which stem from campus network. This paper regards the solution of IP address embezzlement as the starting point. On the basis of grasping the principle of IP address embezzlement, the paper analyses carefully the limitation of dualistic and ternary theft-proof model, along with the limitation of theft-proof model based on ARP protocol. After further investigating SNMP protocol, and aiming at the structure of our campus network, the author finally proposed a kind of new theft-proof scheme of four-layer model based on SNMP and user login and switch control. At the same time the theft-proof system is realized with a B/S structure and the functions of monitor, localization, warning, block network communication. Accordingly it defends effectively IP Address embezzlement.更多还原
