defenses against data breaches due to cyber-attacks are a challenge, there are many information leakages caused by insider threats. In this paper, an insider is a user (employee) with legitimate access privileges and malicious intentions. Because they have legitimate access privileges, it is quite difficult to clearly detect their signs by existing security countermeasures. In this paper, we propose a method to narrow down insiders by dynamically placing decoy files for users who have abnormal behaviors and monitoring access tendencies of the decoy files. Using decoy files, we expect insider’s malicious intentions would be much more visible. By placing decoy files with content that would attract an insider near files with abnormal accesses, we expect that the method can detect insider threats effectively without hindering the normal operations of legitimate users.
