Abstract

The possibility of dynamic routes change between nodes that are not physically connected is a key feature of the Internet routing. The exterior gateway protocol BGP‑4 has been developed to deliver this feature, along with policies and procedures of inter-domain routing. Developed for the network of hundreds nodes that rely on information from each other, after decades BGP-4 is still the same with tens thousands nodes and its crucial lack of routing data integrity. One of the most significant problems deriving from its weaknesses is route leaks and route hijacks. None of the proposed and partially implemented upgrades and add-ons like MANRS and RPKI can not deliver reliable defense against those types of attacks. In this paper, the approach of risk assessment via internetworking links analysis is developed. Although modern information security is based on risk management, in this paper it is proposed to mitigate route hijack risks by enhancing links topology. Estimating the risks of route hijack requires quantitative measurement of the impact of an attack on the routing distortion, and therefore, the loss of information security breach. For this assessment, this paper proposes to use knowledge of the features of the Internet topology at the layer of global routing, which is determined by the interaction of autonomous systems - groups of subnets under common control - according to the routing protocol BGP-4. Based on our formal representation of IP routing, the relationship between topology and the risk of route hijack is shown. A new approach to quantifying information risk using a new risk-oriented model of global routing, which will reflect the properties of Internet nodes in terms of the risk of routes hijack.
