Abstract

The invention relates to a network security monitoring method and device for an electric power plant station, computer equipment and a computer storage medium. The network security monitoring method of the electric power plant station comprises the steps of determining each network behavior feature vector of the electric power plant station in a training time period according to network flow dataand host log data of the electric power plant station, Wherein the network behavior feature vector records a behavior identification parameter and a time parameter of a network behavior, and the training time period comprises a plurality of unit time periods; Determining behavior parameters of each network behavior in each unit time period in the training time period according to the behavior identification parameters and the time parameters; Determining a confidence interval of the network behavior in a unit time period according to the behavior parameter of each network behavior; And obtaining current parameters of each network behavior in the current unit time period, and carrying out security monitoring according to the current parameters of the network behaviors and the confidence intervals of the network behaviors. The method can improve the safety monitoring effect of the electric power plant station.

Description

technical field [0001] The invention relates to the field of network technology, in particular to a method and device for network security monitoring of electric power plants, computer equipment, and computer storage media. Background technique [0002] With the introduction of strategies such as the Industrial Internet and Industry 4.0, the digitization of industrial production has become an irresistible future trend. With the wide application of computer technology and network communication technology in power industry control systems, traditional power industry control systems have gradually broken the previous closedness and proprietary nature, and standard and general communication protocols as well as software and hardware systems have become more and more widely used. The Stuxnet virus incident in Iran in 2010 pushed the information security of the industrial control system to the forefront, and the information security vulnerabilities and hidden dangers of the indust...
