Security science in Czech Republic only postulate its scientific terminology. Difficulties in communication within and outside the newly created and evolving multidisciplinary scientific field is also reflected in the development and application of new concepts.

Examples are the concepts of “security”, “interest”, “threat”, “risk”, “conflict” and others. Described unsatisfactory state of interdisciplinary shared a few overarching security terminology has led to the emergence of Czech security terminology.
