路由协议安全是网络安全的重要组成部分。本文深入分析了OSPF的安全特性,讨论了OSPF当前版本提供的安全机制中存在的安全漏洞及可能遭受的攻击,介绍了目前针对这些漏洞所提出的防范策略,文章的最后提出了基于报文分析的OSPF路由协议攻击检测系统。 关键词:OSPF路由协议;安全性;报文分析;攻击 Abstract: The security of routing protocol is the most important partition of the network security. This article analysises the secure characteristics of OSPF and discusses the vulnerabilities in security mechanism provided by the current version of OSPF, and point out the possible threat. The article then introduces the existing solutions that address some of the current threats. Lastly, we present the system of detecting attacks against OSPF routing protocol based protocol packet analysis. Key words: OSPF routing protocol; security; packet analysis; attack
