Identification of Vulnerabilities in Web Services using Model-Based Security
Abstract
In a service-oriented architecture, business processes are executed as composition of services, which can suffer from vulnerabilities. These vulnerabilities in services and the underlying software applications put at risk computer systems in general and business processes in particular. Current vulnerability analysis approaches involve several manual tasks and, hence, are error-prone and costly. Service-oriented architectures impose additional analysis complexity as they provide much flexibility and frequent changes within orchestrated processes and services. Therefore, it is inevitable to provide tools and mechanisms that enable efficient and effective management of vulnerabilities within these complex systems. Model-based security engineering is a promising approach that can help to fill the gap between vulnerabilities on the one hand, and concrete protection mechanisms on the other. The authors present an approach that integrates model-based engineering and vulnerability analysis in order to cope with the security challenges of a service-oriented architecture.
