Tourism is a phenomenon that has different dimensions and types and in a way, one can say that the entire political, cultural, social and economic system of a country is involved. Given that a systemic attitude towards the security and sustainable development of tourism is becoming increasingly important. The purpose of this article is to examine the necessity of planning and systemic attitude of the government towards the security and sustainable development of tourism in metropolises of Iran with an emphasis on the metropolis of Tehran. The main question of the article is that the reasons for the planning and attitude of the system of governance regarding the security and sustainable development of tourism in the metropolis of the Iranian cities? The hypothesis we are trying to investigate and analyze is to answer this question the sovereignty of phenomena should, in principle, be a system and tourism, in addition to necessity, also has an inner necessity which is due to the nature of this phenomenon. This article is an analytical descriptive where will try using library resources as well as scientific and research papers to analyze and explain the subject. The results of this article also show that tourism and sustainable development in Iran require management and planning, especially in the field of security promotion and the two in the group have a systemic attitude from the government. Metropolitan evidence of Iranian cities, and in particular Tehran, suggests the separation and insularity of the areas of security and sustainable development of tourism and the non-systemic attitude in these areas
