The Smart Spaces Safety and Security for All Cities (S4AllCities) project focuses on systems that ensure the safety and security of city residents. Smart cities have a responsibility to provide a safe physical and digital environment that supports cohesion and sustainable development in relation to citizens. S4AllCities integrates technology and organisational solutions in a market-driven unified Cyber-physical security management framework, aimed at increasing the resilience of urban infrastructure, services, ICT systems, IoT and promoting information sharing and awareness between urban agglomeration components in the fields of safety and security.
