The Border Gateway Protocol (BGP) controls much of Internet traffic, but is vulnerable to communications interruptions and failures; finding suitable improved security measures with acceptable costs is difficult. Recent high-profile outages and security analyses clearly indicate that the Internet routing infrastructure is highly vulnerable. Moreover, the design of BGP and the ubiquity of its deployment have frustrated past efforts at securing interdomain routing. This paper considers the current vulnerabilities of the interdomain routing system and surveys both research and standardization efforts relating to BGP security. We explore the limitations and advantages of proposed security extensions to BGP, and explain why no solution has yet struck an adequate balance between comprehensive security and deployment cost.
It has been well-known that the Internet routing is vulnerable to various misconfigurations and attacks REF .
