ecurity and state of peace are fundamental values and setting priorities of every individual, and also of every community said individual takes part in. In that sense, security can be considered a necessity of every live being, and also a precondition for the development of persons, societies and countries. Security of the state as a community is realized through political-military alliances and affiliating with collective safety systems, but also by counting on own forces and protection of property, systems and subsystems which are inevitable for maintaining vital social functions, health,IV security, protection, and economic and social wellbeing of the people. Such systems are collectively named critical infrastructure, because malfunction or destruction of such infrastructure, caused by natural or anthropogenic factors, can have major consequences on the overall national safety, and thereby affect the health and lives of people, assets, the environment, the economic stability and the constant function of authorities. The safety of critical infrastructures is the main priority of the national security, and it comprises of all accessible activities and initiatives which aim at the enhancement of protection of said factors. The collective approach is one of the functional ways of protecting critical infrastructures, and it includes the partnership between the holder of public and private security, since the fundamental task of both of them is above all the protection and safety of lives and assets, and prevention and elimination of hazards.
