The skills results of a cyberattack on ICS infrastructure at an aluminium plant could be particularly disastrous. Aluminium smelting comes to an electrolysis course of that requires gigantic amounts of electrical energy. This is why aluminium smelters are commonly found close to hydroelectric power plants. The gigantic amount of electrical energy is needed because of the amount of warmth that’s needed to smelt aluminium. Aluminium smelters have many cells—every now and then called pots— wherein electrolysis happens, these pots are required to be kept hot during operation.
