Abstract
A detection device includes: a statistic unit that acquires statistical value data on 5-tuple flows in a certain time period; a degree centrality calculation unit that calculates a degree centrality of a node including an indegree, which is a total sum of a weight of each edge flowing into the node, and an outdegree, which is a total sum of a weight of each edge flowing out of the node, based on the statistical value data on the 5-tuple flows in the certain time period; and a degree centrality impartation unit that imparts the degree centrality, as a feature, to the statistical value data on the 5-tuple flows in the certain time period.
