During the turn of the second millennium, in the world around us, there are many political, economic and social crises, mass migration, 4th industrial revolution, asymmetric warfare, a new type of terrorism phenomenon which became increasingly known to larger masses, making a virtual development into their rooms. Most of these events have developed in line with accelerated changes and have spread through globalisation and data transfer developments. In my study, I examine whether a direct link between migration and terrorism can be detected between the subjects of their own citizenship, regular and irregular migration and registered terrorist attacks. If it is a verifiably existing phenomenon, what kind of law enforcement options can reduce the risk of terrorism and reduce the risk of migration.
