PROBLEM TO BE SOLVED: To provide an unauthorized access detection system and an unauthorized access detection method capable of discovering unauthorized access at an early stage without imposing much burden on a manager.SOLUTION: An unauthorized access detection system includes a storage section for storing an entrance exit log that records the entrance time or exit time of a user, a terminal operation log that records operation of a user to a terminal, and a server operation log that records operation to a server from a terminal, and a trail management section that merges each log to rearrange it in chronological order for each user and for each terminal to output a report that identifies a user who has illegally accessed or has performed illegal operation to the server by comparing the entrance time or exit time of the user with the terminal operation log and the server operation log.SELECTED DRAWING: Figure 2 |
