SCADA Systems Vulnerabilities and Blockchain Technology

SCADA systems are one of the most important part of industrial operations. Before SCADA, plant personnel had to monitor and control industrial process via selector switches, pushbuttons and dials for analog signals. As manufacturing grew and sites became more remote, relays and timers were used to assist supervision. With the onset of technology and advent of network based protocols, these systems became more reliable, fast and it became easy to troubleshoot problems. Indeed progress also brings vulnerabilities, which was no new for SCADA. The IP protocols brought threat to the security of these systems. The devastation that cyber predators on SCADA can inflict, could be illustrated by the Stuxnet virus attack. This paper discusses what SCADA systems are, their uses, protocols being used by these systems, vulnerabilities and ways to combat those vulnerabilities. It focusses on the use of Blockchain Technology as a step in security of such systems.
