Traffic anomaly analysis for the detection of aberrant network code

摘要

A method for detecting nodes in an enterprise network infected with aberrant code is presented in which traffic conversation information representative of traffic conversation in the enterprise network over an analysis period is obtained. Analysis of the obtained traffic conversation information identifies suspected infected nodes in the enterprise network that exhibit behavior outside of the normal behavior associated with the one or more traffic conversation factors. Anomaly analysis may be performed on traffic conversation information associated with the suspected infected nodes to identify any existing infected nodes in the enterprise network.
