A Novel Approach to Determine Software Security Level using Bayes Classifier via Static Code Metrics

Technological developments are increasing day by day and software products are growing in an uncontrolled way. This leads to the development of applications which do not comply with principles of design. Software which has not passed security testing may put the end user into danger. During the processes of error detection and verification of developed software, static and dynamic analysis may be used. Static code analysis provides analysis in different categories while coding without code compile. Source code metrics are also within these categories. Code metrics evaluate software quality, level of risk, and interchangeability by analysing software based on those metrics. In this study, we will describe our web-based application which is developed to determine the level of security in software. In this scope, software's metric calculation method will be explained. The scoring system we used to determine the security level calculation will be explained, taking into account metric thresholds that are acceptable in the literature. Bayes Classifier Method, distinguishing risks in the project files with the analysis of uploaded sample software files, will be described. Finally, objectives of this analysis method and planned activities will be explained.
