Crime prevention strategies are one of the topics in the field of criminology that are developed in order to control and manage crimes by using different governance and community capacities before, during and after the crime. Given the great influence of the mass media in this regard, the purpose of this study is to investigate the role of the media in crime prevention and security.

In terms of its objectives the present study is of an applied research type and in terms of its nature it is considered as descriptive-survey. The statistical population is 81 individuals in charge of crime prevention and the sample size is calculated as 67 individuals based on Cochran's formula with at least 5% error. The instrument used was a researcher-made questionnaire. The reliability of the questionnaire was 89% by measuring Cronbach's alpha coefficient. The validity of the questionnaire was evaluated and confirmed using expert opinion and face validity. The collected data were analyzed using SPSS software and t-test, Friedman and regression tests.

Findings indicate that mass media are directly and indirectly effective in crime prevention and public security by emphasizing public culture-making with a total of 0.498. According to Friedman test, to determine the priority of different functions of media influence in crime prevention and public security, the function of culture-making through the media with a rate of 2.94 compared to other functions, was prioritized.

Public culture building, modeling and providing inferential and informational needs of public culture are effective in preventing crime. As a result, those in charge of crime prevention in the society should take an interactive and participatory approach and use the negative and positive functions and capacities of the media in a specialized and correct way to generalize the culture of crime prevention and security in the society

The country's cyberspace is a space of communication networks in which useful content and services are provided within the framework of Islamic principles and values ​​and the country's laws and regulations, and despite the many benefits, creating a platform for cybercrime risks to security. Virtual and consequently the national interests of the country.Due to the lack of a clear strategic model in this regard, the present development-applied research aims to achieve a strategic model of international cooperation to improve cyberspace security based on the national interests of the Islamic Republic of Iran and with a case-by-case approach to cybercrime. Mixed), while collecting and studying the relevant theoretical foundations, noteworthy concepts (qualitative data) Draws and codifies (categorizes, categorizes, measures, and categorizes the research method by MaxiCode software software (methodology, components, and indicators) and then models the structural structural equations in Smart PLAS software by modeling. Extracting 4 main hypotheses and 10 sub-hypotheses for evaluation, model expertise by snowball method by questionnaire, from faculty members, operational managers and strategic managers familiar with the field of research (statistical community) and by analyzing and analyzing the obtained quantitative data, Kelly assessed the model as strong.The research results showed that 12 approved hypotheses, 2 rejection hypotheses and global indicators of cyberspace security (bilateral agreements, multilateral agreements, organizational partnerships, public and private partnerships, international partnerships) are also effective tools for improving cyberspace security.

Any abnormality in the environment, either stemming from nature or human, could have severe consequences for human life and national environmental security. Each one of environmental problems including air pollution, fossil fuels, municipal and industrial wastes, etc, could somehow affect environmental security. Meanwhile, this study aims to determine environmental constituents which affect environmental security. Doing so, it poses the question: what are environmental constituents in respect, and what impacts could each one of them have on others and on the environment's security. Following, it gathers data through questionnaire and calculates the reliability by means of Cronbach's method. To analyse the data, it applies one-variable T Test and to sequence the significance, it applies Friedman Test, and also to predict the participation of each one of the 9 factors, it exploits linear regression. Finally, the direct and indirect impact of independent variables is revealed through the analysis. The outcome of the study suggests that social problems, production of dangerous wastes, public ignorance, change in land use, unsuccessful strategies, weak performance of responsible institutions, air pollution, and inappropriate dispersion of urban and industrial engineering are the environmental constituents which affect the environment's security. In conclusion, it is revealed that social problems (increase of the population living under subsistence level, inequality of incomes, unemployment, nutritional requirements and public ignorance) affect environment's security more than other factors.
