目前基于IPv4的校园通信网络显示出诸多弊端,如地址空间有限、安全性差等。IPv6的安全性同IPv4相比有了明显的提高,但存在应用层和协议本身的安全性,校园网本身也存在诸多应用安全问题。本文首先论述了IPv6协议及其安全性特点,详细分析了IPv6环境下的校园网络安全问题和技术漏洞,阐述了基于IPv6的校园网入侵检测系统的必要性,提出了一个IPv6入侵检测系统以及在IPv6校园网中的应用。
At present, IPv4-based campus communication network shows many disadvantages, such as limited address space and poor security. Compared with IPv4, the security of IPv6 has been obviously improved, but there are security of application layer and protocol itself. There are also many application security problems in campus network itself. This paper first discusses the IPv6 protocol and its security features, analyzes the campus network security issues and technical loopholes in IPv6 environment in detail, expounds the necessity of campus network intrusion detection system based on IPv6, and proposes an IPv6 intrusion detection system as well as IPv6 campus network applications.
