Embodiment 1
[0051] figure 1 It is a flowchart of an industrial control system information security attack risk assessment method according to an embodiment of the present invention, figure 2 It is a structural diagram of an industrial control system information security attack risk simulation device according to an embodiment of the present invention.
[0052] see figure 1 and figure 2 , the method for assessing the risk of an attack on an industrial control system information security in this embodiment is applied to a simulation device for simulating the risk of an attack on an industrial control system information security.
[0053] Industrial control system information security attack risk simulation environment is an important part of the industrial control system information security laboratory. The simulation environment is the liquid level control system, among which the liquid level control system is a highly versatile industrial control system, which can easily realize the ...
Embodiment 2
[0072] This embodiment provides a more detailed implementation manner.
[0073] The risk assessment method for information security attacks on industrial control systems provided in this example divides industrial systems into five risk warning levels: red, orange, yellow, blue, and green, extracts four categories and eighteen risk assessment indicators, and establishes a risk assessment Model. This method is applied to the information security attack risk simulation device of industrial control system. The simulation device also takes the water tank liquid level control system as the object, and helps the research by simulating information security attack, industrial control system damage evolution and damage risk level early warning. Researchers have a comprehensive understanding of the situation of information security attacks on industrial control systems, and formulate appropriate countermeasures. The invention can effectively reduce disaster loss and improve the securit...
Embodiment 3
[0112] This embodiment provides an industrial control system information security attack risk assessment system, image 3 It is a structural diagram of an industrial control system information security attack risk assessment system according to Embodiment 3 of the present invention. see image 3 , the system includes:
[0113] The indicator data acquisition module 301 is used to acquire risk assessment indicator data; the risk assessment indicator data includes four types of data, which are respectively control object state data, control algorithm parameters, attack type data and control environment state data; each type of data includes A plurality of parameter values; the control object state data includes six parameter values, which are respectively the liquid level of the first water tank, the liquid level of the second water tank, the opening degree of the first overflow valve, and the opening degree of the second overflow valve , the opening degree of the communication...
