What Internet of things would be to consumers, SCADA and Industrial control systems would be to enterprises, the heavy machinery that we have been thinking of its intelligent management is going to be completely taken over by the technology. Although it looks like a great boon however if take over, we have seen in the past some of the national critical infrastructures of some very developed countries being compromised and the damages happening which are irreversible hence it becomes most important to understand the cyber risks that such technologies posses and to give the education of the best practices followed for securing such technologies.
