One of the fundamental functions of governance is to provide security and social peace for its citizens. In this context, crime and, particularly, the fear it generates in contemporary cities are considered among the primary obstacles to achieving sustainable security and a desirable quality of life. The paradigm of penal governance regards crime prevention as a key strategy for confronting this phenomenon. Among preventive approaches, Crime Prevention Through Environmental Design (CPTED) has gained significant prominence in recent decades by emphasizing the physical and spatial design of urban environments to reduce opportunities for crime. However, the emergence of the novel "smart city" paradigm and transformations in urban governance methods have revealed the necessity to revise and evolve traditional CPTED principles. This article, employing a descriptive-analytical method and based on library resources, seeks to elucidate the theoretical framework of "Smart CPTED" within the context of smart urban governance. This framework expands the traditional concept by leveraging functions such as natural surveillance, access control, territoriality, and maintenance, elevating it from a merely reactive state to a predictive and proactive level. The research findings indicate that smart urban governance, through the integration of advanced analytical technologies like artificial intelligence and data networks within the city's cyber-physical infrastructure, opens a new chapter in crime prevention. This novel approach is not solely focused on the hardware and physical dimensions of the city but emphasizes social dynamics, enhancing the quality of life, and strengthening citizen participation in digital environments as fundamental pillars for ensuring sustainable security.
