OSPF 路由项欺骗攻击研究与防御策略：原理、实施与演示平台

摘要

OSPF (Open Shortest Path First) 是一种常用的内部网关协议 (IGP)，用于在企业网络中的路由器之间交换路由信息。然而，OSPF 协议存在漏洞，可以被攻击者用于实施路由项欺骗攻击。在这种攻击中，攻击者发送虚假的路由信息，使得路由器将流量发送到错误的目的地。本文分析了 OSPF 协议的路由项欺骗攻击原理和实施方法，并介绍了 OSPF 协议的防御策略。本文还介绍了一种基于开源软件 Quagga 的 OSPF 路由项欺骗攻击演示平台，以便于学生和研究人员了解和研究该攻击。

Abstract

OSPF (Open Shortest Path First) is a commonly used Interior Gateway Protocol (IGP) used to exchange routing information between routers in enterprise networks. However, the OSPF protocol has vulnerabilities that can be exploited by attackers to implement routing item deception attacks. In this attack, the attacker sends false routing information, causing the router to send traffic to the wrong destination. This paper analyzes the principles and implementation methods of the OSPF protocol's routing item deception attacks and introduces the defense strategies of the OSPF protocol. This paper also introduces an OSPF routing item deception attack demonstration platform based on the open source software Quagga, which facilitates students and researchers to understand and study the attack.
