Document Type and Number:
WIPO Patent Application WO/2020/170802
Kind Code:
A1
Abstract:
A feature quantity calculation unit (15b) calculates a feature quantity of header information of a packet. A classifying unit (15c) classifies the packet as being normal or abnormal, using the calculated feature quantity. An allocating unit (15d) allocates, to the header information of a packet that has been attacked using a known attack tool, a label indicating the tool name of the attack tool. A learning unit (15e) learns label allocation by using the label and the feature quantity calculated with respect to the labeled packet as teacher data.
