In addition to software and hardware components, media assets include physical and infrastructure assets and assets. Therefore, in order to deal with threats against these assets and reduce vulnerability, it is necessary to develop strategies to protect these infrastructures with a passive defense approach, which has been proposed as the main goal in this study. The present study is descriptive-analytical and data collection through Internet, library and field methods and the main method of data analysis is SWOT method and also Cronbach's alpha coefficient and statistical tests have been used to measure the questionnaires. In this study, after reviewing upstream documents and obtaining expert opinions, 92 environmental factors affecting the protection of this infrastructure have been identified and evaluated in SPSS software. Then 21 strategies were developed based on the strategy formulation model of the Higher National Defense University. According to experts, one of the priority strategies can be planned to increase the deterrent capability in cyber threats, scientific, research and training development of the required manpower using the existing capacities in the country to increase relevant specialized knowledge, hedge, strengthen national media infrastructure against severe threats. Using local experts, increasing material and moral support of knowledge-based companies active in the field of development projects in the field of satellites related to national media, localization and application of artificial intelligence knowledge to establish a monitoring system and cyber attacks and help protect national media infrastructure in Against threats, purchasing and reverse engineering, he cited examples of advanced software systems in the field of national media.

The purpose of this study was to investigate the role of the national media in managing the crisis and maintaining the peace of the citizens in the district 22 of Tehran. In this study, a descriptive survey method was used. The statistical population consisted of the citizens of Tehran in the district 22 in 2017 that was 129 thousand people. Based on the available sampling method, 384 people were selected as sample using the Cochran sampling formula. The data gathering tool was a questionnaire in this research. The questionnaire used was regulated by combining models on the role of national media in crisis management and maintaining peace between citizens. Reliability of the questionnaires was measured and confirmed by Cronbach's alpha test. The data were analyzed using descriptive and inferential statistical methods including Kolmogorov-Smirnov test and binomial test using SPSS software.The research results showed that national media included cultural-social conferences, films and television series, children's and adolescent's programs, television animations, news and training programs, has role on crisis management and maintaining the peace of the citizens.

One of the important goals in current wars is to disable information and communication systems, specifically enemy broadcast. Since the role of national broadcast in controlling public opinion is inevitable, the continuation of its work, during a crisis, is doubled. The most important issue in signal performance stabilization is to keep communication between receivers and transmitters, which is generally done through earth or satellite transmission. This study was conducted to answer how, by utilizing passive defense measures, we can stabilize the efficiency of national broadcast against the threats caused by a war and what procedures can help us to keep on earth and satellite transmission. The hypothesis was discussed by a group of 60 managers and technical experts for emergency caused by a war, utilizing modern signal transmission through a passive defense approach. That how we can stabilize the performance of the national broadcast, in a crises caused by a war, needs a survey on the factors of a stabilized broadcast in such a situation. Using modern transmission procedures such as SFN – STMI – IPTV, capabilities like RDS in radios, SNG, satellite signal transmission capability and passive defense measures were among the initial practical proposals. After analyzing the data, the following result was acquired: using different parallel signal transmission, mobile transmitters, dispersion, camouflage, concealment, STMI, information coding, applying balloons for transmission and mobile receivers are among appropriate ways in a crises caused by a war.
