ITC system security in the context of contemporary challenges for electric power industry

In recent years, electric power systems, in order to improve their efficiency, are increasingly using the latest innovations in the field of information and communication technologies (ICT) starting from wireless communication and fiber optics systems. Both used for industrial automation purposes and complex data analysis. Those systems, year by year, have made use of more and more sophisticated communication algorithms leading to automatic management of energy distribution process as well as undertaking the system resuscitation tasks as a result of failure. The use of ICT communication equipment in electric power systems is certainly a big advantage, but it also entails some safety issues. The traditional understanding of smart grid cyber security involves the general requirements (placed on existing systems) as well as specific solutions for detection and intrusion prevention (for individual parts of the system infrastructure). Implementation of security policy in management process of the power system, with means of modern technical of digital information transmission, will increase efficiency and reliability of those systems.
