Abstract:

Aiming at the problem of business continuity security management,a key business node identification model for the business process is proposed.First,the node set to be evaluated is obtained according to the business process,the node importance evaluation attributes are quantified according to the importance of the business nodes,and the business node importance decision matrix is constructed by combining with the business node set to be evaluated and the value of the business node evaluation attributes.Second,the evaluation attribute weight of business nodes is improved from the subjective and objective dimensions,the importance combination weight decision matrix of business nodes is constructed,the AE-VIKOR (Analytic hierarchy process and Entropy weighting VIKOR,AE-VIKOR) method is used to calculate the importance coefficient of business nodes,and the key node is identified.Finally,when a security event occurs in a system,the effectiveness and accuracy of the model are proved by comparing and analyzing the impact of the implementation of key businesses and the other businesses on business continuity.Experimental results show that the node importance coefficient is calculated by the AE-VIKOR method in the model,and that the key business node is identified according to the node importance coefficient.The experiment further compares and analyzes the impact of key business nodes and other business nodes on business continuity,and compares the identification results of the AE-VIKOR method and other methods and different decision coefficients,with the results showing that the model identification is efficient and accurate.

Key words: information security, key business node, AE-VIKOR, business continuity
