Abstract
The Border Gateway Protocol (SGP") is an interautonomous system routing protocol.BGP IS used to exchange routing information for the Internet and is fhe protocol usedbetween Internet service providers (ISPV Customer networks, such as universities andcorporations, usually employ an Interior Gateway Protocol (IGP) such as RIP or OSPFfor the exchange of routing information within their networks. Customers connect toISPs, and ISPs use BGP to exchange customer and ISP routes. When BGP is usedbetween autonomous systems (AS), the protocol is referred to as External BGP (EBGP).If a service provider is using BGP to exchange routes vsdthin an AS, then the protocol isreferred to as Interior BGP (IBGP).A current trend of network security issues is for attackers to target routers to disruptnternet traffic. Due to the lack of a scalable means of verifying the authenticity andlegitimacy of the Border Gateway Protocol (BGP) control traffic, BGP is highlyvulnerable to a variety of malicious attacks both in theory and in practice. Whiletremendous effort has been devoted to network security, and a number of effective attackcountermeasures have been developed and implemented, little attention has been paid tothe inter-domain routing protocol attacks and network devices' security features. Ourproject identifies the BGP security issues, the BGP protocol vulnerabilities andweaknesses, and the possibilities that BGP traffic may be affected.
