Software development is the outcome of complex processes involving a large number of people. Bridging the gap from architecture and specifications to the final implementation is only one of the challenging tasks that developers have to face. In addition, the interaction and communication between the diverse players  has to be mastered throughout the engineering process. Languages, methods, and tools in the engineering process need to support the  variety of perspectives of the players involved. Fraunhofer SIT develops and optimizes standardized engineering methods that can guarantee a defined level of IT security. The focus is on support for stakeholders who are not experts in IT security, yet need to be equipped to take the right IT-security design decisions.
