Why are these issues relevant now? Because earlier this month, there were reports that the blackouts in Mumbai last year happened because of cyberattacks from China. Unfortunately, in India, it is believed that much of the power systems have embedded Chinese systems, thereby making them potentially compromised. However, one need not connect these power systems to the internet. There can be, what is technically referred to as an “air-gap” between the power systems and the internet, thereby foiling any cyberattack through the internet. An “air-gap” implies that there is no connectivity between the internet and the said systems. However, as was demonstrated in the cyberbombing of the Iranian nuclear facilities in 2010, and subsequent cyberattacks on the Iranian power plants in 2012, demonstrated that a cyberattack can be launched even if the systems are not connected to the internet, by compromising people involved with the systems.
