Example Embodiment

[0046] In order to solve the technical problem of high false positive rate in the multi-type attack detection system applied to the physical level existing in the prior art, in the embodiment of the present application, a stacked denoising autoencoder (Stacked DenoiseAutoEncoder, SDA) is used to The level of traffic is used for feature learning and dimensionality reduction. After expanding the dependency between features, it is input into a model that combines 1D_CNN with a residual module and GRU. After obtaining the predicted features, it calculates the statistical deviation from the actual features, and judges according to the size of the deviation value. Whether the system is abnormal. The problem of high false positive rate of the multi-type attack detection system currently applied on the physical level is solved. Among them, the false positive rate: in the set of actual observed traffic is normal traffic, the probability that the model predicts that it is abnormal. Hig...

Abstract

The invention relates to the technical field of computers, in particular to an industrial control system anomaly detection method and device, a server and a storage medium. The method comprises the steps of obtaining a historical traffic data set, and performing noise reduction processing on any historical traffic data in the historical traffic data set to obtain a feature vector of any historicaltraffic data; inputting the feature vector into a data traffic prediction model, and outputting a prediction feature vector of subsequent data traffic; and adjusting parameters of the data traffic prediction model according to the prediction feature vector of the subsequent data traffic and the real feature vector of the subsequent data traffic, so that the updated subsequent prediction feature vector meets a preset requirement. According to the invention, the technical problem of low detection accuracy of an industrial control system anomaly detection method in the prior art is solved.

Description

technical field [0001] The present application relates to the field of computer technology, and in particular to an abnormality detection method, equipment, server, and storage medium of an industrial control system. Background technique [0002] Industrial Control System (Industrial Control System, ICS) refers to a collection of equipment, systems, networks and controllers used to operate, control, and assist automated industrial production processes, including data acquisition and monitoring systems (SCADA, Supervisory control and data acquisition) , Distributed Control System (DCS, DistributedControl System) and other systems that perform control functions. Industrial control systems are widely used in all walks of life, including energy, electric power, petroleum, transportation, chemical industry, etc. They play a vital role in national infrastructure and are related to the national economy and people's livelihood. Therefore, once it is successfully attacked, it will b...
