The world globalisation processes have inevitably been accompanied by the development of new forms of crime and the occurrence of crisis incidents (acts of terrorism, major transportation accidents, construction accidents, or natural disasters). The above phenomena increase the demand for knowledge, the use of which may directly or indirectly influence the effectiveness of agencies responsible for internal security. With its basic goal of spreading the knowledge of the protection of public safety and order, the scientific journal Internal Security is one of the many ventures aimed at meeting the demand. The journal is oriented towards security aspects of universal scope. It is a forum where views and opinions are exchanged by specialists of various branches (both scientists and practitioners) from different countries, and in particular European ones. Entrepreneurs of non-public sector are welcome to exchange their opinions in the journal, as well. In many cases methods and mechanisms which are used to ensure safety are of universal nature and they can be applied by both, public and non-public sectors.
