AHP and grey correlation-based multidimensional network security evaluation method

Abstract

Aiming at the problem that network security evaluation indexes are one-sided and difficult to strictly quantify, an AHP (Analytic Hierarchy Process) and grey correlation-based multidimensional network security evaluation method is proposed. The method includes the steps of 1. establishing a multidimensional network security evaluation model; 2. determining weights of factors contained in each model of the multidimensional network security evaluation model established in Step 1 based on the AHP; and 3. quantifying network security based on a grey correlation theory: representing security of a network to be evaluated through quantification of a similar degree.

Description

technical field [0001] The invention relates to a multi-dimensional network security assessment method based on AHP and gray correlation, and belongs to the technical field of network security. Background technique [0002] With the implementation of the "Internet +" action plan, network security attacks will intensify, and network security threats have become one of the serious challenges affecting national security and economic development. For example, due to the recent ransomware attacks that broke out in many countries around the world, China’s campus network has also become a hard-hit area. Many colleges and universities across the country have been infected by viruses. A large number of students’ graduation thesis and other important materials have been encrypted and tampered with by viruses. Only by paying a ransom can they recover , which has brought a huge negative effect to people who are in the college graduation season. [0003] In order to deal with the increa...

Problems solved by technology

Most of the existing network security assessment methods start from the static security attributes of information systems, focus on descriptive and isolated assessment system security, and lack comprehensive analysis of different dimensions

At the same time, although some studies have quantified the risk value for certain methods, because they did not consider the interaction of various factors, the factors evaluated are not systematic enough to accurately quantify and reflect the security status of the network
