Satellite network security analysis method, device, system and storage medium

Abstract

This application relates to satellite network security analysis methods, devices, systems and storage media. The method includes: obtaining satellite network equipment security data and completing the model construction of satellite network security ontology; according to the four-level model of satellite network security equipment, performing equipment security data After unified processing, the satellite network security hierarchical model and the satellite network security knowledge model are respectively formed; the entity name, attribute and mutual relationship are abstracted from the satellite network security hierarchical model and the satellite network security knowledge model, and are formally expressed by setting description language as The dynamic triples are used to obtain the dynamic graph model; then knowledge reasoning and graph dynamics analysis are carried out based on OWL+SWRL language, and the auxiliary construction of the satellite network equipment security knowledge map is completed; the security problem query statement is obtained and the knowledge reasoning and analysis are carried out through the constructed knowledge map. Query and analyze to obtain information on security weaknesses of the satellite network. The analysis efficiency of weak links in satellite network security has been greatly improved.

Description

technical field [0001] The present application relates to the technical field of satellite network security, in particular to a satellite network security analysis method, device, system and storage medium. Background technique [0002] With the development of satellite technology, satellite networks play a key role in almost every field, so the importance of satellite network security is particularly prominent, and even directly related to national security and social stability. Therefore, for units and departments that value satellite network security, how to identify and deal with space network weapon threats and further in-depth analysis and processing of satellite equipment security issues are problems that need to be solved urgently. Due to the current multi-source and heterogeneous information on satellite network security incidents and the loose organizational structure, it is difficult to efficiently use the information. Moreover, the current satellite network atta...

AI Technical Summary

Problems solved by technology

[0003] However, at the current legal level, there is a lack of international cybersecurity standards, regulations and treaties for satellites

At the technical level, there are many weak links in the complex manufacturing and operation and maintenance of satellites, making satellites extremely vulnerable to cyber attacks

From the opponent's point of view, unlike the use of laser anti-satellite weapons, which are easy to detect, cyber-attack anti-satellite weapons are more concealed, and the cost may be lower, which makes the risk of satellite destruction greater

To sum up, in the process of realizing the present invention, the inventor found that in the aforementioned traditional satellite network security technology, there is a technical problem of low analysis efficiency of network security weak links
