Security is an important quality aspect for modern information systems. Security properties may however be violated if the information system operates in an evolving environment. Environmental changes then trigger reactions which lead to co-evolution of the security design and the corresponding system model. However, updating the security design manually is time-consuming and error-prone. We present an approach to support semi-automatic system co-evolution which responds to environmental knowledge evolution, using the UML security extension UMLsec and graph transformation. The aim is to enable software engineers to react more reliably and effectively to environmental changes and to ensure lifelong compliance of information systems. To evaluate our approach, we conducted a case study on the open-source project iTrust.
