A Model-Driven Approach for Securing Software Architectures


Current IT systems consist usually of several components and services that communicate and exchange data over the Internet. They have security requirements that aim at avoiding information disclosure and at showing compliance with government regulations. In order to effectively handle the security management of complex IT systems, techniques are needed to help the security administrator in the design and configuration of the security architecture. We propose a model-driven security approach for the design and generation of concrete security configurations for software architectures. In our approach the system architect models the architecture of the system by means of UML class diagrams, and then the security administrator adds security requirements to the model by means of Security4UML, a UML profile. From the model enriched with security requirements, the concrete security configuration is derived in a semi-automated way. We present a tool that supports this model-driven approach, and a case study that involves a distributed multi-user meeting scheduler application.
