In Ukraine there was a cyberattack, which resulted blackout for 1-6 hours to over 200,000 people. This attack targeted SCADA-system. SCADAsystems are one type of industrial control system and they are used, among other things, to control and monitor the intrinsic performance of electricity and water supply. They differ in part from the purpose and function of traditional information technology. The cyberattack targeted to SCADA-system can have significant damage to human health and safety and deal great damage to the environment, so it is important to examine cyber-security in this context. Statistics show that the number of cyberattacks targeted to SCADA-systems has increased over the years. This literature review explores the cybersecurity of SCADA-systems; its special features and requirements compared to traditional information technology, cyberattacks on systems, and potential improvements in cybersecurity of SCADA-systems. It was noticed during the examination that SCADA-systems have started to use the same technologies in part as in traditional information technology. This exposes SCADA-systems to new kinds of cyber threats and attacks. In addition, it was found that there are many practices and methods for improving cybersecurity. During the examination it was noticed that pivotal methods for improving cyber security of SCADA-systems are simulation and modeling techniques. When using and developing these methods, it must be considered that there are specific requirements in SCADAsystems functioning, such as the real-time operating, the limited computing resources, and the continuity and safety requirements for functioning.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted by Paivi Vuorio (paelvuor@jyu.fi) on 2019-05-10T11:48:23Z\nNo. of bitstreams: 0", "language": "en", "element": "description", "qualifier": "provenance", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Made available in DSpace on 2019-05-10T11:48:24Z (GMT).
