Abstract:
In the present invention, a list-type detection unit (220) detects an illegal communication by performing list-type detection on communication data. A machine learning-type detection unit (230) detects an illegal communication by performing machine learning-type detection on communication data. A communication reception unit (210) receives communication data from a network, and uses an allocation filter to allocate the received communication data to at least one of the list-type detection unit and the machine learning-type detection unit. A filter setting unit (250) determines a parameter value on the basis of the load status of the list-type detection unit and that of the machine learning-type detection unit, and sets the determined parameter value to the allocation filter.
