Information Security Risk Assessment In Power Plant

The article analyze the importance and feasibility of information security risk assessment in power plant. According to the GB draft <>, and refer to the assessment process and computation thought of it, take Datang Taiyuan second thermal power plant as the object, study out a set of operational quantification model of information security risk assessment. Regarding to macroscopic of risk computation model and refinement of implement in the GB graft<>,The article take the quantification method to analyse main factors as far as possible, construct a judgment matrix according to the judgment criterion quantification rule which is usually used in AHP ,calculate out characteristic vector and consistency index of the matrix, realize the quantification analysis of risk influence value. The article give out some benefit suggestions and reference of information security in power plant through the researching of the risk quantification model and developing of assessment software .
