Research on security vulnerabilities information collection system

The research on the design of network vulnerability database is of great significance to network security.In order to use the information of vulnerability databases and provide more flexible application interfaces,a security vulnerabilities information collection system model based on several mature vulnerability databases is proposed.The system model consists of two parts: information collection sub-system and information integration sub-system.The information collection sub-system makes the information collection and updating strategies according to sources of the database.The information integration sub-system makes integrates of the databases based on CVE name of vulnerability.The implementation mechanisms of information collection and integration are studied,so that the extensibility,information comprehensiveness and flexibility of application interface are guaranteed.
