Abstract
A feature calculation unit calculates a feature of header information of a packet. A classification unit classifies the packet as a normal packet or an abnormal packet by using the calculated feature. An adding unit adds a label indicating a tool name of a known attack tool to header information of a packet attacked using the attack tool. A learning unit learns the addition of the label by using the label and the feature calculated for the packet to which the label has been added as teacher data.
