Network security threat analysis is an important component of network security assessment. Traditional threat analysis methods cannot effectively integrate multi-source information and adapt to the rapidly changing network attack and defense situation. To address the above issues, a network security threat analysis method based on knowledge graph is proposed. Firstly, this article constructs a network security ontology model, which models the concepts and relationships in the field of network security, and then associates and integrates multi-source network security information. Next, this article constructs a network security knowledge graph based on ontology. Then, a network security threat path prediction, traceability, and analysis method based on knowledge graph is proposed to accurately perceive cyberspace security threat. Finally, by comparing with traditional threat detection methods, it is verified that the network security threat analysis method based on knowledge graph proposed in this article is more suitable for perceiving high-strength security threat.
