Abstract:

Based on the analysis of the factors that affect information security risks,a hierarchical information security assessment model is established. A risk analysis method based on fuzzy AHP is proposed to evaluate risks. This method adopts the triangular fuzzy number to represent the experts＇ judgment m matrix of risk factors based on group decision, and uses AHP to handle these risk factors, thus provides reasonable data for decision-making.
