An Approach to Obtain Software Security Vulnerabilities Based on Vertical Search

we propose an effective approach to obtain software security vulnerabilities in web with vertical search technique in this paper. We use a keyword-trainer to get domain keywords in software security domain. Then the web page filter is designed after analyzing the obtained domain keywords and the structure of the URL topology. Finally, we design a vertical search crawler based on the webpage filter to search for the information of software security vulnerabilities in Web. This approach effectively discovers and digs out the information of software security vulnerabilities presenting in Web. It helps provides the primary knowledge and information for constructing security-knowledge database and analyze the vulnerabilities of software.
