PROBLEM TO BE SOLVED: To make it possible to reliably detect spoofing on a user.SOLUTION: A spoofing detection system 1 comprises: a storage device that stores a plurality of types of logs on a user of a cloud service; and a computation device that groups the plurality of types of logs on each user per session of the user in the cloud service, generates a first integrated log by aggregating a prescribed item of the respective logs per grouped session, creates a profile on the user applying the first integrated log to prescribed algorithm, generates a second integrated log by performing grouping and integrated log generation about logs obtained after that, collates the second integrated log with the profile to determine a spoofing risk, and outputs prescribed information on a prescribed device if the risk is higher than a prescribed threshold.SELECTED DRAWING: Figure 1 |
