Recent reports show that the loss from the malicious intrusion by insiders is more serious than by outsiders. Despite that the various attacks are occurred by insiders and outsiders, most work has been focused on the intrusion detection against outsider attacks. In this paper, the authors improve the Wang et al.'s insider prediction model and propose the combined model with access control for the efficient insider intrusion detection. The authors delegate the role of insider intrusion detection to users that reduces the malicious trial of insiders and the overhead on the centralized intrusion detection system.
