Abstract:

Vulnerability database is an important part of information security infrastructure used for storing
vulnerability information. This paper introduced topic Web crawler into the vulnerability database maintenance
system, in which the webpages that are related to vulnerabilities can be accessed through topic Web crawler and
the vulnerability information can be abstracted so as to update the vulnerability database. This technology
reduced the workload of maintenance and resolved the problems of coverage incompletion and lack of information in
the existing vulnerability database. By analyzing the structure of the existing vulnerability database at home and
abroad, studying the association of vulnerability attributes, and implementing group classification description
method, this paper built a vulnerability database syntactic model. It also came up with a dynamic topic
construction scheme for vulnerability topic, introducing design and implementation of vulnerability database
maintenance system.

Key words: topic Web crawler, dynamic topic, vulnerability model, vulnerability database
