Abstract
An analysis apparatus analyzes access logs including authentication results and authentication information of users, and includes: a calculation unit that calculates a similarity between pieces of authentication information in two consecutive access logs when access logs of the same access source, from the access logs, are chronologically arranged, and presumes that a piece of authentication information of the access logs of the user has been input by a human if the calculated similarity is equal to or greater than a predetermined value; and a risk determination unit that determines that there is a possibility that the access source in the access logs is being an attack source if an authentication result of any of the two access logs is authentication failure and the calculation unit presumes that any piece of authentication information of the two access logs has not been input by a human.
