The purpose of the study is to identify the role of informal social control in achieving community security in the South Sinai Governorate by recognizing the role of customs, customs and traditions in achieving community security and recognizing the extent to which Bedouins respect tribal leaders and obey their orders. The descriptive study was based on a number of research methods, namely the social survey method in the sample, including a representative sample of all the nine governorates and villages, valleys and Bedouin communities. The study used the appropriate tool. The questionnaire contains 77 closed questions, including two open questions. A sample of 300 persons was easy for the respondents. The illiteracy rate was 28%, and the study used social control theory. The study reached several results, including a statistically significant role for informal social control in achieving community security. The results also indicate that the Bedouins like to live in groups, and that their social relations are distinct in their interdependence and compliment each other in joy and joy and enjoy and enjoy security, where they have no incidents of killing or theft or cutting roads. The results also indicated their keenness to participate in the elections. Informal social control mechanisms were not an impediment to women's participation in elections. They respect the elders and obey their orders, although the degree of respect among young people now and the elderly has declined. They also prefer customary justice to the formal elimination of the speed of adjudication in disputes and their sense that customary law is a preventive security, despite their knowledge of official security rules. In view of the results, it is possible to recommend the following: • Strengthening community security in the governorate by establishing industrial projects to attract the largest number of Bedouin residents to work in it, since tourism often needs specializations that are not available in the Bedouin. • Construction of factories next to the quarries instead of manufacturing them outside the Sinai and thus will not deprive Badawi from working. • The need to codify informal social control rules and incorporate them through scientific studies because they are all oral, and technological advances in communications can expose them to extinction.
