Yixian Yang · Beijing Youdian Xueyuan xuebao · 2008
According to the characteristic of uncertainty information in the information system risk analysis process,and information system risk measurement using entropy theory,a risk analysis algorithm using entropy-weight coefficient is presented.When combining qualitative analysis and quantitative calculation,a model of information system risk analysis is constructed.Finally,an instance of the risk analysis approach based on the model is analyzed and validated,which demonstrates the rationality and feasibility of the model.So it provides a new method for information system risk analysis.
