20. A network security method comprising:
receiving a plurality of pieces of communication data from a network;
selecting one or more pieces of communication data from the plurality of pieces of communication data that have been received, using a selection filter;
accepting the one or more pieces of communication data that have been selected, and performing list-type detection on the one or more pieces of communication data that have been accepted so as to detect a fraudulent communication;
accepting each piece of communication data from which a fraudulent communication has not been detected by the list-type detection, and performing machine-learning-type detection on each piece of communication data that has been accepted so as to detect a fraudulent communication; and
