Terrorism as a contemporary security challenge

Terrorism is one of the greatest challenges to modern security. In this paper, we try to explain how terrorism is regulated in the legislation of the Republic of Serbia and how and in what way it affects the security of the Republic of Serbia and surrounding countries. Starting with the AP of Kosovo and Metohija, where terrorism appears in the 1990s in the idea of creating a "Greater Albania". Terrorism as a phenomenon is based on the use of violence and an ideology that is religiously, racially or ethnically firmly determined. Terrorism as a crime in our legislation is one of the most serious crimes classified in the category of crimes against humanity and other goods protected internationally. What is considered a problem in the fight against terrorism is that even today there is no generally accepted understanding of what terrorism really is? This phenomenon, which is already gaining momentum today, is constantly advancing in every sense, and it is necessary to start finding a path that leads to controlling this phenomenon. By violating human rights and other material goods, terrorism threatens the global order.
