Urban spaces, streets, squares, and parks in a city are among places where public activities are occurring. Some other spaces, where due to the lack of visual outlook, are unprotected and more capable of committing crime. The current research was conducted in unprotected urban spaces in the Navab street of Tehran. It aims to study the origins of criminal activities in this district and to provide solutions to increase security based on women participation in society. This qualitative study was conducted via grounded theory approach, emphasizing on Durkheim’s anomie theory, Wilson and Kling’s theory of broken windows. The participants included 40 individuals who resided in Navab Street and neighborhood of Salamat Park in District 11 of Tehran. Social and cultural conditions of residents, the degree of satisfaction of families living in this area, disruptions have been occurred in the functioning of residents were under examination in the survey. The findings indicated three major categories of social security including threat to family health (physical and psychological), and disruption in socio-cultural constructive actions. According to the results, local women considered participation in solving district’s problems to be inconclusive. Dominance of this view in the families had adverse effects on the quality of their life. The study encourages women to occupy these spaces for selling their hand works, trying to put an end on the dominance of criminals and offenders in these spaces.
