Cyber Security Provision for Industrial Control Systems

The paper gives an overview of the infrastructure of the electric power control system. It describes the basic threats caused by unauthorized actions and provides examples of the energy management system infrastructure vulnerabilities and their possible consequences. An architecture of a system that offers an effective protection of the Industrial Control Systems from cyber threats is described in some details. The test scenarios used for the system verification and the results of experiments performed both in Supervisory Control and Data Acquisition testbeds and in a operational power control substation are also presented.
