Technology has made it possible to remotely connect to control systems from anywhere in world with any device capable of Internet access. This capability provides many operational benefits such as being able to maintain and support systems with remote staff, to supply operational data to Enterprise Resource Planning (ERP) systems and regulators, and to enable vendors to provide support and updates to the system. These benefits notwithstanding, allowing remote access to a control system, especially remote access over public networks (e.g. the Internet), can be extremely risky. Since the risk varies with the application, the decision whether to allow remote access to an ICS should always be based on the results of an ICS Cybersecurity Risk Assessment
