Border Gateway Protocol (BGP), is the most important internet protocol. It defines the rules of communication and enables independent computer networks to connect with others and join the global network. In this paper, we introduce some of the basic BGP concepts, as well as some of the well-known flaws. Then we discuss the three most widespread solutions, developed to fix certain secutiry challenges: S-BGP, IVR and SoBGP. In the end, we simulate prefix hijacking attack using GNS3, aimed at a backbone network. Several scenario are demonstrated: an unprotected network is first attacked, then we repeat the attack after applying a filter, and in the end, after manipulating several BGP attributes.
