In the past two decades, urbanization and industrialization in developed countries have led to the emergence of complex cities that are vulnerable to both natural and human-induced disasters. The advancement of information technology and the transition toward smart cities have played a significant role in improving urban management. However, achieving this goal requires meticulous planning to reduce vulnerabilities and enhance security in urban infrastructure. Urban planning must be aligned with the principles of passive defense to ensure the resilience of city infrastructure against potential threats. This research focuses on District 4 of Tehran Municipality to examine safety and smart infrastructure in greater depth. The primary objectives of this study are to identify and interconnect essential urban infrastructure for resilience, analyze the factors influencing the resilience of smart city infrastructure, and propose planning solutions to enhance infrastructure resilience in smart cities based on a passive defense approach. The research adopts an exploratory-analytical methodology. Data collection was conducted through observation, interviews, literature review, and questionnaires. Data analysis involved content analysis, Cronbach's alpha calculation, and various statistical tests, including the Likert scale, Kolmogorov-Smirnov test, t-test, and Friedman test. The SPSS software was used for scoring and statistical eva‎luation. The research findings indicate a significant correlation, with a score of 4.16, between the physical-environmental aspects of urban planning and passive urban defense. The physical-environmental component was identified as the most influential factor in risk reduction during crises in District 4 of Tehran Municipality. Consequently, the greatest impact on smart city infrastructure resilience, following a passive defense approach, is attributed to the physical aspects of this region. Strengthening these infrastructures can significantly reduce vulnerabilities and enhance urban resilience.
