Knowledge Graph Construction Research From Multi-source Vulnerability Intelligence

Abstract There is a huge Internet user group in China, and many enterprises and institutions are deeply affected by the threat of Cybersecurity vulnerabilities. At present, according to the needs of different business scenarios, relevant business personnel often need to search for different vulnerability information separately, relying on manpower, and the vulnerability intelligence distributed on the Internet has the characteristics of multi-source heterogeneity, which is difficult to ensure the effectiveness and reliability of vulnerability knowledge. In view of the above background, with vulnerabilities as the core, knowledge extraction of vulnerability intelligence is carried out according to existing standards, corresponding entities and relationships are established, and related and visualized knowledge graphs are studied and constructed to provide support for the discovery and traceability of vulnerability threats by information workers.
