Large-scale network security situation evaluation method based on index system

Abstract

The invention provides a large-scale network security situation evaluation method based on an index system. The method comprises the following steps: step one, determining dimensions that are needed to be analyzed for a network security situation; step two, determining network security factors according all the dimensions; step three, determining concrete indexes according to all the network security factors, wherein the dimensions, the security factors, and the concrete indexes are all-level nodes of a hierarchical evaluation model; and the step four, carrying out security situation evaluation on the hierarchical evaluation model to obtain a network security value. According to the method provided in the invention, efficiency of large-scale network security situation evaluation can be improved.

Description

technical field [0001] The invention relates to the field of computer network security, in particular to a large-scale network security situation assessment method based on an index system. Background technique [0002] With the development of human society, the network has been integrated into all aspects of people's lives. While the network brings great convenience to people, it is also accompanied by security issues that cannot be ignored. The security of information systems is seriously threatened. At the same time, after my country's network informatization level has developed to a certain stage, various network security incidents have increased, such as network economic crimes, large-scale network attacks, network stealing, etc., which have become restrictions on the development of my country's national economy, and even endanger social stability and national security. safety factor. [0003] In view of the increasingly severe network security situation, how to compre...

Problems solved by technology

[0005] This method is mainly aimed at the threats caused by network attacks in the LAN environment, and is not suitable for the security threat assessment of large-scale network systems; hosts and services in large-scale network environments present a large-scale distribution characteristic. If aggregated according to the above model, There are disadvantages such as slow calculation speed
