随着校园网络规模的不断扩大,用户数量也不断的增加,各种病毒与木马程序的泛滥,使得IP地址盗用十分普遍。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。本文以解决IP地址盗用问题为出发点,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。
With the continuous expansion of campus network size, the number of users is also increasing, the proliferation of viruses and Trojans, making IP address theft is very common. Not only negatively affects network charging but also disrupts normal network operation and application. Therefore, solving the problem of IP address misappropriation is the primary condition for ensuring the safe operation of campus network and tracing and preventing network attacks from campus network. In this paper, to solve the problem of IP address misappropriation, this paper proposes a new anti-theft technology based on SNMP, a four-element model combining user registration and switch control.
