PROBLEM TO BE SOLVED: To make it possible to determine the details of abnormality detected on a network.;SOLUTION: The present invention relates to a communication analysis device that detects abnormality on a network. The communication analysis device of the present invention comprises: a plurality of abnormality detection means that detect the degree of abnormality from information generated in a network device arranged on the network; feature amount generation means that extracts information corresponding to condition information from the information generated in the network device to generate as a feature amount and supplies the feature amount to the respective abnormality detection means; output vector generation means that accumulates results of detection output from the respective abnormality detection means by the condition information and generates a result of accumulation as an output vector; and final determination means that performs final determination processing for finally determining the details of the abnormality generated on the network on the basis of the output vector.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2019,JPO&INPIT
