Design and Implementation of Vulnerability Platform Based on Knowledge Graph

Security vulnerabilities are an important part of the cybersecurity field. These vulnerabilities are dispersed across numerous websites and forums, exhibiting multi-source heterogeneity and data redundancy, and showing a significant growth trend. This presents a challenge for the collection, sharing, and analysis of vulnerability information. To address this issue, this paper presents a novel knowledge graph-based vulnerability platform. The platform fuses the vulnerability data collected by crawlers through a knowledge graph, obtaining 1.72 times more vulnerability data than NVD, 2.05 times more than CNVD, and 4.69 times more than NSFocus. This reflects the effectiveness of knowledge graph in fusing heterogeneous vulnerability data. Furthermore, the vulnerability platform provides data services that are easily queryable and retrievable, thus facilitating the early warning and repair of security vulnerabilities.
