Through the Looking Glass: Classifying Anomalous BGP Communities
Abstract
The Border Gateway Protocol (BGP) community field is poorly defined and has no means of authentication. This BGP attribute has the power to reroute and black hole traffic across the internet. The BGP communities path attribute is normally prevalent and persistent. I hypothesize the persistence and prevalence of the path attribute can be used to develop a BGP community anomaly detector. This anomaly detector will allow for the discovery of and filtering out both malicious or misconfigured BGP community announcements. Future work could build upon the detection of anomaly and define the anomaly. In addition, an anomaly detector can be used to limit the spread and power of anomalous BGP communities.
