The creation of a Common Body of Knowledge (CBK) on engineering secure Future Internet services. The goal is then to collect, extend and integrate knowledge, thus constituting an European common body of knowledge in the area. This CBK will be constituted having openness to all the interested stakeholders as a major objective. We integrate existing knowledge and complement this with new insights that emerge from interdisciplinary research. Ultimately, a handbook for a working secure software engineer will be produced, among many other results in this area.
