Cloud platform safety quantitative evaluation method based on improved VIKOR method

Abstract

The invention discloses a cloud platform safety quantitative evaluation method based on an improved VIKOR method. The cloud platform safety quantitative evaluation method comprises the following steps of S1, determining the index system and attribute of cloud platform safety quantitative evaluation; S2, preprocessing index attribute data, and establishing an evaluation basis matrix; S3, converting the evaluation basis matrix into a standardized decision matrix; and S4, establishing a cloud platform safety evaluation model, and obtaining the evaluation result ranking index of each evaluation scheme in dependence on the evaluation model. Aiming the characteristic, of the cloud platform, that each evaluation factor has dynamic nature and relevance, a new decision matrix establishing method is provided, and therefore defects and deviations of a conventional VIKOR decision matrix processing method in the evaluation information set aspect can be overcome, scientificity, objectivity and comprehensiveness of safety evaluation can be obtained at the same time, and the accuracy of the cloud platform safety evaluation result can be improved.

Description

technical field [0001] The invention relates to a cloud platform security quantitative evaluation method based on the improved VIKOR method, and belongs to the technical field of cloud platform security evaluation. Background technique [0002] With the rapid development of global computer technology, cloud computing technology has become the core of a new generation of technological revolution, and has been widely used in government affairs, commerce, education, data centers and other fields. The cloud platform provides users with convenient and fast services, including rapidly expanding storage space, computing power and lower deployment costs, but at the same time, adopting cloud computing technology means putting the core data and business of tenants under their own control Therefore, the security issues of cloud platforms have attracted more and more attention. Cloud computing platforms usually use shared IT infrastructure, breaking the boundaries of traditional inform...
