Orchestrating security and system engineering for evolving systems

How to design a security engineering process that can cope with the dynamic evolution of Future Internet scenarios and the rigidity of existing system engineering processes? The SecureChange approach is to orchestrate (as opposed to integrate) security and system engineering concerns by two types of relations between engineering processes: (i) vertical relations between successive security-related processes; and (ii) horizontal relations between mainstream system engineering processes and concurrent security-related processes. This approach can be extended to cover the complete system/ software lifecycle, from early security requirement elicitation to runtime configuration and monitoring, via high-level architecting, detailed design, development, integration and design-time testing. In thi s paper we illustrate the high-level scientific principles of the approach
