Document Type and Number:

WIPO Patent Application WO/2021/171526

Kind Code:

A1

Abstract:

A detection device (10) has: a statistic unit (131) for acquiring the statistical value data of a 5-tuple flow in a fixed period; a degree centrality calculation unit (132) for calculating, on the basis of the statistical value data of the 5-tuple flow in the fixed period, the degree centrality of a node that includes an in degree that is the sum total of weights of edges flowing into the node and an out degree that is the sum total of weights of edges flowing out of the node; and a degree centrality addition unit (133) for adding the degree centrality, as a feature quantity, to the statistical value data of the 5-tuple flow in the fixed period.
