However, the deployment of the RPKI authentication mechanism is not high at present, and the number of protected prefixes only accounts for one-fifth of the total number of prefixes. Therefore, the scope of existing BGP hijacking detection is relatively limited, and there are still malicious attackers impersonating Possibility of a prefix owner

The present disclosure provides a method, device, device and medium for detecting BGP hijacking based on MOAS conflict events. The method includes: acquiring real-time routing data, and detecting MOAS conflict events based on the real-time routing data; and based on timestamps of the MOAS conflict events and observation points to obtain a MOAS matrix; determine whether the MOAS conflict event is an abnormal MOAS conflict event based on the behavior characteristics of the MOAS matrix; in response to the MOAS conflict event being an abnormal MOAS conflict event, determine that BGP prefix hijacking occurs. According to the present disclosure, it is judged whether the MOAS conflict event is abnormal through the behavioral features shown in the MOAS conflict event, and then the occurrence of BGP prefix hijacking is detected. There is no need to rely on third-party authentication mechanisms, which reduces deployment costs.
Description
technical field [0001] The present disclosure relates to the field of communication technologies, and in particular, to a BGP hijacking detection technology. Background technique [0002] Border Gateway Protocol (Border Gateway Protocol, BGP) is a routing protocol that realizes the reachability of routes between autonomous systems (Autonomous Systems, AS) and selects the distance vector of the best route. However, the BGP protocol lacks security considerations at the beginning of its design, and there are many security loopholes. For example, there is no authorization and authentication mechanism, the received BGP routing information is not authenticated, and the routing information cannot be guaranteed in the process of routing propagation. In other words, the AS completely trusts the routing reachability information from neighbors, including false routing information due to misconfiguration or malicious forgery. As a result, the BGP protocol has become the target of many ...
