Association Analysis Algorithm Based on Knowledge Graph for SPACE-Ground Integrated Network

The Space-Ground Integrated Network (SGIN) plays an important role for the future development of the country. The cyber-attacks against it are the focus of the research. In this paper, an association analysis algorithm based on knowledge graph of cyber security attack events is proposed to present the attack scenario for the Space-Ground Integrated Network. The construction of knowledge graph and association analysis can show the scene of cyber-attacks in the form of graphs. During the build process, the construction of an event ontology is an important part of it. Event ontology is used to represent various relationships in the network attack procedure. At last, we present a space-ground integration network security analysis system based on the knowledge graph of cyber security attack events, and uses the association analysis algorithm to analyze the attack scenario.
