Modern concept of security

Abstract

It is obvious that understanding of security in the past was not the same as it is today, nor will be such in the future. While security once meant only the preservation of lives, today it is the preservation of the society, community, nature and technical systems that serve the man. Security is a complex concept whose definition has not been reached by general consensus of the society. The reasons for the above mentioned status of the concept of security are numerous. The main reason can be found in different perceptions of the term, which have different causes. The most common issue is the determination of the scope of the concept of security, but there are also reasons that result from different understanding of security. The paper points to problems of defining and understanding the security, and presents also new security concepts through the ideas of the Copenhagen School of Security Studies. Challenges, risks and threats have been observed and classified as well.
