Abstract
A detection apparatus extracts an account and a source address of the account from authentication information obtained from an authentication apparatus configured to perform user authentication, groups accounts for each of time slots at predetermined time intervals and each of source addresses in accordance with a timestamp and the source address of the account, and extracts an account group from which duplication of an identical account in an identical group has been excluded. Subsequently, the detection apparatus calculates the number of duplicate accounts among the extracted account groups. The detection apparatus determines that an identical source address is an address of an attacker in a case where the number of account groups of the identical source address in which the number of calculated accounts exceeds a first threshold exceeds a second threshold.
