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

Abstract

The invention relates to a satellite network safety analysis method, a device, a system and a storage medium. The method comprises the steps of obtaining equipment safety data of a satellite network and completing model construction of a satellite network safety ontology; uniformly processing the equipment safety data according to the satellite network safety equipment four-level model, and respectively forming a satellite network safety level model and a satellite network safety knowledge model; abstracting entity names, attributes and interrelationships from the satellite network safety hierarchy model and the satellite network safety knowledge model, and formally expressing the entity names, attributes and interrelationships as dynamic triples by adopting a set description language to obtain a dynamic graph model; carrying out knowledge reasoning and graph dynamics analysis based on an OWL + SWRL language, and completing auxiliary construction of the satellite network equipment safety knowledge graph; and obtaining a safety problem query statement, and performing knowledge reasoning and query analysis through the constructed knowledge graph to obtain safety weak link information of the satellite network. The analysis efficiency of the satellite network safety weak link is 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
