Abstract

Access control systems are nowadays the first line of defence of modernIT systems. However, their effectiveness is often compromised by policymiscofigurations that can be exploited by insider threats. In this paper, we presentan approach based on machine learning to refine attribute-based access controlpolicies in order to reduce the risks of users abusing their privileges. Our approachexploits behavioral patterns representing how users typically access resourcesto narrow the permissions granted to users when anomalous behaviors are detected. The proposed solution has been implemented and its effectiveness has been experimentally evaluated using a synthetic dataset.
