| Research Abstract |
We have developed a method for security requirements analysis. In the method, vulnerabilities and their countermeasures are systematically predicted on the basis of the dependencies among assets and a system architecture in a system to be developed. We can re-examine vulnerabilities and their countermeasures when the architecture is changed but system functionalities are not changed. We have also developed a supporting tool for enacting the method. The tool consists of three components: a modeling editor, a model checker and a visualizer. With the help of the tool, stakeholders including security experts can validate the predicted results of the method because the tool can automatically derive the candidates of vulnerabilities on the basis of our original model checking engine and visualize the derived results.
