Contemporary perceptions of security

Security is perceived by various groups of theorists and practitioners in different ways, and at the turn of the 20th and 21st century, security theory research gained momentum. The concept of security has become important not only in the social, natural or technical sciences, but also in social life, in international relations, and in many research programmes and applications. The term security has systematically expanded as a result of civilization progress to include hitherto unknown challenges and threats and new means and ways of eliminating them. In the past, security was based mainly on the preservation of the military capacity to defend the vital interests of a given social group. The multitude of definitions of security has led to the creation of a separate field of study in the literature, known as securitology. It represents an individual field of human-centred research and assumes that all actions of the human individual are directed towards maintaining security. Security is a separate field of research focusing on the human being and assumming that all actions of the human individual are directed towards ensuring a sense of security. The issue is multifaceted, and the discipline indicated is new, and has only begun to be of interest since 2010.
