Abstract

This detection device (10) acquires a network log and a host log of an apparatus. The detection device (10) converts the network log into network feature values that are in a format enabling the values to be input into a multi-modal generative model, which generates output data on the basis of a plurality of latent variables that are expressed as random variables. The detection device (10) converts the host log into host feature values that are in a format such that the values can be input into the generative model. The detection device (10) inputs at least one from among the network feature values and the host feature values into the generative model, and calculates output data. The detection device (10) uses anomaly scores calculated on the basis of the output data to detect anomalies inthe apparatus.

Description

technical field [0001] The invention relates to a detection device and a detection method. Background technique [0002] In recent years, the IoT has become widespread, and all devices have been coordinating operations through the network to generate various values. On the other hand, there is a vulnerability that various devices are not considered to be connected via the network. Also, at the earliest stage of IoT popularization, a large number of devices with insufficient security measures are connected to the network. [0003] Due to this situation, anomaly detection technology for IoT becomes important. Anomaly detectors can be classified into list-type detectors and learning-type detectors. The list type detector is a type in which human beings design detection conditions according to each IoT device. Also, a learning type detector is a type of detector that learns detection conditions from data. [0004] Since there are many types of IoT devices, the learning type...
