A mining approach for component abnormal information based on monitor log

A software component is an assembly unit that can be deployed independently in any software system. Since the source code and development documents of software components cannot be obtained, the vulnerability testing for software components is a challenge for component users. Explicit and implicit vulnerabilities are two common security vulnerabilities in the components. In this paper, in order to detect security vulnerabilities in the component under test effectively, a mining approach for component abnormal information based on monitor log is proposed. For explicit vulnerability, the monitor log is mined with the improved apriori algorithm, and the risk coefficient of each method in component is calculated with the frequent item sets algorithm based on the mining results. For implicit vulnerability, all the method execution sequences in monitor log should be extracted and stored into a database to establish the method sequence database. The vulnerability testing report will be obtained by mining the met...
