Requirements-driven runtime reconfiguration for security

Abstract

The boundary between development time and run time of eternal software intensive applications is fading. In particular, these systems are characterized by the necessity to evolve requirements continuously, even after the deployment. In this paper we focus on the evolution of security requirements and introduce an integrated process to drive runtime reconfiguration from requirements changes. This process relies on two key proposals: systematic strategies to evolve architecture models according to security requirements evolution and the combination of reflective middleware and models@runtime for runtime reconfiguration. © 2012 Springer-Verlag.
