Automatic detection and distribution prevention of incorrect BGP-4 routing information

Mansurov Alexandr Valerievich, Schetinin Daniil Sergeevich

Route leaks and route hijacking are the most known actions that cause severe problems for BGP-4 routing and affect the overall connectivity and reliable operation of the Internet. The proposed solution enables automatic identification of route leaks and hijacked routes relying on the information from the Internet routing registries. The solution does not require modification of current software of BGP-4 routers of a monitored telecom carrier. Routes being identified as suspicious or malicious are effectively blocked by the proposed solution thus preventing further distribution of such routes by the monitored telecom carrier and affecting its directly connected neighbors.
