Abstract
An extraction unit-extracts a specific request from among requests that do not match with a profile on the basis of a similarity to a request to a server, where the profile determines whether the request is an attack. Further, a determination unit determines whether the specific request extracted by the extraction unit meets a predetermined condition indicating that the specific request is continuously transmitted from a certain number or more of transmission sources. Furthermore, a control unit relearns the profile if the determination unit determines that the specific request meets the predetermined condition.
