Strategies for Addressing Link State Routing Protocol Vulnerabilities: A Panoramic View

Executive Summary

The link state routing protocol is the most widely used intra-domain routing protocol, which is used to distribute and maintain routing information among various routers within a domain. Unfortunately, this protocol is vulnerable to several security attacks. These attacks may be as simple as packet sniffing or as sophisticated as the insider attack. Research has been done to enhance the security of the protocol, but either falls short of providing substantial security or suffers from practical implementation issues. In spite of all these efforts, the research world lacks a comprehensive threat model specific to the link state routing protocol.
