Abstract

The invention discloses an information system security situation assessment method based on a correction matrix-entropy weight membership cloud. The information system security situation assessment method comprises the following steps: S1, establishing an evaluation index system; S2, standardizing the multi-source data; S3, determining an index weight vector; S4, quantifying and grading the security situation of the information system; and S5, grading the security situation of the information system. Compared with the prior art, according to the information system security situation assessmentmethod based on the correction matrix-entropy weight membership cloud provided by the invention, the optimal deterministic matrix can be found by correcting the interval judgment matrix on the premise of reserving subjective evaluation of experts, so that the weight vector of the index layer is determined, and the security situation is quantified and graded in combination with the entropy weightmembership cloud. Through comparative analysis with an evaluation result based on an entropy weight coefficient method and a traditional AHP method, it is shown that the information system security situation assessment method has good stability, feasibility and effectiveness, and enables the safety situation quantitative evaluation result to be more reasonable.

Description

technical field

[0001] The invention belongs to the technical field of network information security, in particular to an information system security situation assessment method based on a correction matrix-entropy weight subordinate cloud. Background technique

[0002] The development of information technology has promoted the application of information systems to many fields of society, such as finance, military, and industry and commerce. However, the main factors restricting the function of information systems have changed from the technical level to the security supervision level. Because information systems involve many aspects such as software / hardware systems, network systems, and management systems, and because of the complexity of the application environment, they face threats such as physical security risks, software / hardware security risks, and confidentiality security risks. This shows that information system security is facing a severe test. In order to facilit...
