The current understanding for effective security policy of the critical energy infrastructure focuses on the ability to systematically assess vulnerabilities, predict threats and neutralize the risks of cyber attacks on the interdependent elements of the complex, intelligent energy infrastructures. There are three major new developments in the security policy concerning the functioning of the critical energy infrastructure – cyber security, public-private partnership and international cooperation in the development and implementation of the policy for security of critical energy infrastructures. Various countries and international organizations offer their own policy models, while their efficiency is yet to be proven.
