Power plant control system information security risk assessment system

Abstract

The invention relates to a power plant control system information security risk assessment system. The system comprises an index assignment module used for performing data input for a preset risk assessment index system model to obtain an index assignment sample; a first weight module used for solving an index influence weight vector of the index assignment sample through a D-AHP method; a second weight module used for solving an accuracy weight vector of the index assignment sample through a TOPSIS method; and a grade output module used for integrating the index influence weight vector, the accuracy weight vector and the index assignment sample to obtain the information security risk grade of the evaluation object. Compared with the prior art, risk assessment can be accurately and effectively carried out through a few sample values, a large amount of manpower and material resources are saved, meanwhile, the problem that a few samples are high in subjectivity and inaccurate is solved, uncertain sample data can be reasonably processed, and the accuracy of an assessment result is improved.

Description

Technical field [0001] The invention relates to the technical field of information security, in particular to an information security risk assessment system for a power plant control system. Background technique [0002] With the continuous development of industry and the Internet, the information security of industrial control systems has attracted widespread attention at home and abroad. Research on industrial control systems is a major need in the current society. Since the electrical equipment and control information of the entire power plant are interconnected, the potential safety hazards caused by illegal intrusion are very large, so the risk assessment of the information security of the power plant control system is very important. [0003] Commonly used control systems in power plants are mainly distributed control system (DCS), programmable control system (PLC) and field bus system (FCS). However, power plant control systems generally use dedicated software and hardware,...

Problems solved by technology

However, most of the existing evaluation methods use large-scale questionnaires for sample collection, and then obtain the safety risk level through mean value analysis. Such evaluation methods require a lot of manpower and material resources, and there are problems of strong subjectivity and uncertainty. , it is impossible to obtain an objective and accurate risk assessment
