Volatility is one of the most characteristic features of contemporary security. The level of threats increases or decreases, completely new phenomena appear and quickly disturb the global balance and threaten the durability of security systems. This dynamic nature of security verifies both the state and process, as well as their understanding by researchers. The monograph refers to key aspects of the contemporary understanding of security, in its military, political, social, and informational context, as well as other dimensions. It presents and analyzes the identification criteria and determinants of security and characterizes the nature of contemporary threats and the dynamics of their changes. Armed conflicts, terrorism, migration, digital threats, loss of national identity, and populist use of security categories to justify the use of extraordinary measures to combat threats are among the selected areas discussed by the authors. The monograph also raises the issues of cooperation for security, its management and education for security as a key activity to ensure it.weiterlesen
