Abstract

The invention provides an industrial control system information security attack risk assessment method and system, and relates to the technical field of industrial control system risk assessment. Physical entity information and operation information of an industrial control system are obtained and a control system model is established according to the information; constructing a digital twinborn model according to the control system model; determining digital twin data according to the operation information of the industrial control system; training a digital twinning model according to the digital twinning data to obtain an industrial control simulation system; then acquiring and respectively operating the industrial control simulation system according to various attack information to obtain various attack simulation results; then, according to the multiple attack simulation results, a simulation risk value is obtained through calculation according to a preset information security attack risk calculation formula; and finally determining a risk assessment level according to the simulated risk value. The risk assessment is obtained by integrating various attacks and then performing assessment, so that the accuracy of the risk assessment is improved.

Description

technical field [0001] The invention relates to the technical field of risk assessment of industrial control systems, in particular to a method and system for assessing risk of information security attacks in industrial control systems. Background technique [0002] The functional safety and information security of the industrial control system play an important role in the smooth operation of the production of the enterprise. However, the information security of industrial control systems has been neglected. The control commands and status data in the industrial control system face the great danger of being tampered with by criminals in the network, and a series of serious control system attacks may occur, resulting in greater losses. Therefore, how to ensure the information security of the industrial control system has become a key problem that the industry must solve, and it is a research hotspot at present. [0003] As an information security technology that can make i...
