Problems solved by technology

Based on the data obtained from the evaluation of different systems in the same industry in the unified evaluation index system and the calculation of the risk level, it is found from the data which evaluation indicators provide a relatively large amount of information for the risk level, that is, which attributes are more important, and there is currently no relevant technology

Abstract

The invention provides a method and system for acquiring the importance levels of evaluation indexes. The method comprises the following steps of: saving evaluation results of n evaluation indexes X1, X2, ellipsis, Xi, ellipsis, and Xn obtained by using m systems respectively in a data set S, saving the risk level of each system in a data set R, and calculating entropy H (R) of the risk level in the data set R; and acquiring the information gain ratios of n evaluation indexes, and sequencing the acquired information gain ratio to obtain the importance levels of n evaluation indexes X1, X2, ellipsis, Xi, ellipsis, and Xn.

Description

technical field [0001] The present invention relates to the field of information processing, in particular to a method and system for acquiring importance levels of evaluation indicators. Background technique [0002] Information security risk assessment is to use scientific methods and means from the perspective of risk management to systematically analyze the threats and vulnerabilities faced by information systems, assess the degree of harm that may be caused by security incidents, and propose targeted defense measures. Threat protection countermeasures and corrective actions. In the evaluation process, according to the requirements of different industries, the evaluation index and evaluation content of the information system of the industry are put forward, and the final risk level of the system is calculated according to the evaluation index value. [0003] Different industries have different evaluation indicators and evaluation content. Based on the evaluation of diff...
