Abstract
In an organization, the interactions users have with software leaves patterns or traces of the parts of the systems accessed. These interactions can be associated with the underlying software architecture. The first step in detecting problems like insider threat is to detect those traces that are anomalous.
In this paper, we present a method to find anomalous users leveraging these interaction traces, categorized by user roles. We propose a model based approach to cluster user sequences and find outliers. Such a technique could be useful in finding potentially anomalous users, insiders, or compromised accounts.We show that the approach works on a simulation of a large scale system based on and Amazon Web application style. |
