Abstract
The concept of “secure by design” is based on preventive software security and aims at avoiding vulnerabilities as soon as possible. However, finding vulnerabilities manually is a time-consuming and error-prone process. Thus, the use of code scanner tools becomes a good practice for developers. Unfortunately, existing code scanner tools produce too many false positives, which complicates the cycle development task.
In this paper, we present an approach to construct a code vulnerability scanner upon existing scanner tools. The aim of such a scanner, called code vulnerability meta-scanner (CVMS), is to be more efficient and reduce the number of false positives. Our experimental results show that none of the scanners strictly subsumes another, and none of them is better than all the others for all the vulnerabilities. So, we propose a method that combines their results with respect to their performances. We experimented our approach using three existing scanner tools (Fortify, Yag Suite and SpotBug). Then, we used the resulted CVMS to annotate a well-known Java application corpus, namely Qualitas Corpus. These experiment results demonstrated that the CVMS performs better than the scanners on which it is constructed.
