Recent massive data breaches or major security incidents show that threats posed by insiders have greatly increased over time. Especially, authorized insiders can cause more serious problems than external hackers can. Therefore there is a growing need to introduce a system that can monitor the insider threats in real time and prevent data breaches or security incidents in early-stage. In this paper, we propose a EITMS(Enterprise Insider-Threats Management System). EITMS detects the abnormal behaviors of authorized insiders based on the normal patterns made from their roles, duties and private activities. And, in order to prevent breaches and incidents in early-stage, a scoring system that can visualize the insider threats is also included.
