Cities are rapidly becoming smarter, using advanced technology to gather, process, and utilize data about residents and infrastructure. However, there's limited guidance on deploying these systems. This research assumes that Smart Cities are inevitable, Information Systems are their backbone, and cities are new to this cyber reality. Therefore, focusing on Smart Cities Cyber Security (SCCS) is vital for their safety, functionality, democracy, and livability. The challenge is to leverage Big Data's benefits while avoiding privacy and security risks. Key questions include: what are the cyber aspects and vulnerabilities of Smart Cities, what tools can municipalities use to address SCCS challenges, how might the transition affect legal and political structures, and how can cities prevent cyber-attacks and protect data and privacy? This project explores SCCS across planning, technology, social policy, local law, and privacy law, using diverse methods to create a multi-faceted toolkit for designing SCCS. Based on theoretical and empirical studies, especially in Israeli cities leading in smart city development, the focus is on four core dimensions: planning, technology, governance, and privacy. The research will develop policy tools for decision-makers and an integrative model to guide comprehensive policies, tailored to each city's needs, and support technologies that ensure privacy and security.
