The huge diffusion of computational capabilities in embedded systems, cars, smart houses, smartphones, critical infrastructures, e-health, and the penetration of computers and software in enterprises of every dimension have led to an enormous number of victims of cyber attacks. Formal methods are techniques used to mathematically model systems in order to verify properties in a thorough fashion. Thus, formal methods offer the potential to develop secure systems. However, the communities of formal methods and security were not closely collaborating together in the past on solving such important research problems. The aim of the ForSE workshop is to encourage the integration between these two communities towards development of secure and malware resistant systems, thus bridging the existing gap.
