Our daily lifes support by electricity, water and natural gas. In order to maintain the stability and quality of those resources of supply. A analogue to digital (electronics) conversion was done, Thereby those facilities are under governance and control by PLC and SCADA today. However a design limitation was found since the components embedded Microsoft operation system and Linux opensource. So we heard power facilities encountered cyber attacks.
