These attacks are most often made against the weakest points of the systems. Malware infection and other types of attacks of ICS resources can have serious implications including intel gathering, invalid data displayed to operations, and invalid programming sent to controllers. With increasing connectivity between control systems and enterprise networks, the risks of cyber attack on ICS endpoints are increasing. Following best practices for n
