The present article aims to monitor the level of women's security in urban parks first and then identify the parameters affecting women's sense of security and its priorities. The research methodology is quantitative one and its method is a descriptive-analytic study with a specific application of environmental design approach (CPTED), among 400 women from the age 15 to 65 years in Bojnord, according to the cluster sampling method, a proportional and random systematic classification has been made. The results of the study, by verifying and validating the 360 questionnaires, showed that among all the indicators for the CPTED approach, only the social activity support indicator has no role in women's security. But readability, oversight and public perception of space among other indicators of lighting, maintenance management, isolation and population density, signs and overall design of space, which confirmed their significant relationship with women's sense of security, had the highest impact on Women's feelings of security. The isolation and population density also have an inverse relationship with the sense of security. Hence, the sense of women's security can be seen as the result of management and overall design of space that should not be neglected in the policies and urban development process; In other words, if women's presence in some of the city's public spaces is low, this is the result of management structures and its semantic systems in particular regarding the role of women in the development of the city and the physical formulation of it and, therefore, inducing low security feeling for them in these spaces
