Ontology-based Vulnerability Knowledge Graph of Network Routing Mechanism

Knowledge graph is essentially a visual way to present knowledge, which can explore the relationship between knowledge, so as to reveal the dynamic development law of knowledge in specific fields, and realize the sharing and reuse of knowledge. Therefore, the establishment of vulnerability knowledge graph can provide comprehensive and in-depth information support for subsequent vulnerability analysis, which has important theoretical and practical application value. In this paper, by analyzing the vulnerability of the routing mechanism of the space-based network, we designed a fault injection experiment scheme for the typical routing program, realized the dynamic collection of the vulnerability feature information of the network routing mechanism, and constructed the vulnerability dataset of the network routing mechanism. After that, we designed the network routing mechanism vulnerability knowledge graph pattern layer, established the routing mechanism vulnerability ontology model, and finally formed the space-based network routing mechanism vulnerability knowledge graph. The vulnerability knowledge graph of space-based network routing mechanism proposed in this paper has the advantages of visualization and integrity.
