Abstract

The evolution of architecture of contemporary SCADA systems follows trends in industry sector. Today, SCADA systems imply the application of smart grid and artificial intelligence concepts, the use of IP-based technologies, new mobile devices, as well as the use of private and public cloud computing services. Security risk assessment of contemporary SCADA systems needs to include new security aspects. This chapter analyzes information security in contemporary SCADA systems. Focus is then directed to SCADA network architecture and recommended security mechanisms for mitigating the security risk that assumes the use of Defense in Depth concept. Special attention is paid to SCADA-specific intrusion detection and intrusion prevention technologies. A case study outlines recommendations for security risk mitigation of SCADA system in a hydropower plant.
