Abstract
An analysis server accumulates an alert of communication determined not to be normal communication on the basis of a model indicating a feature of normal communication in a storage unit. Then, the analysis server performs clustering of alerts obtained by excluding an alert having a different category variable from communication data used for learning of the model from the accumulated alerts by using a feature amount of communication included in the alert. Thereafter, the analysis server determines, for each cluster generated by clustering, whether or not the cluster includes the same type of alert. Then, the analysis server outputs a result of clustering and a determination result as to whether or not each cluster includes the same type of alert.
