Multidimensional network security measurement method based on TOPSIS

Abstract

The invention provides a multidimensional network security measurement method based on a TOPSIS. The method measures the network security from three dimensions, namely environmental security, vulnerability security and reliability security, selects a relevant metric index under each dimension and quantizes the index, and then evaluates the metric indexes under different dimensions in combination with a TOPSIS comprehensive evaluation method to obtain a network security measurement result, so as to find the defects in the network and improve the network security.

Description

technical field [0001] The invention relates to a TOPSIS-based multi-dimensional network security measuring method, which belongs to the technical field of network security. Background technique [0002] Among the research methods of network security measurement, there are many methods that can be used to measure and evaluate network security. Among them, the most widely used and practical methods are network security measurement methods based on graphs and network security measurement methods divided into dimensions. [0003] The advantage of the graph-based network security measurement method is that it can visually display the connection between the hosts in the network in a graphical way, and calculate it in combination with the theoretical knowledge of graph theory, such as using theoretical knowledge such as graph theory Construct an attack graph, Bayesian network or artificial neural network, so as to perform a series of operations according to the nodes and edges in ...
