It is possible to explain, analyze and understand the international security in six levels:
• Individual level: Security for the individual.
• Societal level: Security for the social group, i.e. ethnic, national, religious, linguistic, or community groups.
• National level: Security for the state or nation.
• Regional level: Security for the region, that is, a coherent security region.
• International level: Security for the international society, the society of nations, and most states in the world.
• Global level: Security for the planet Earth and space (Heurlin and Kristensen, 2010: 69).
