Industrial Control System(ICS) is the generic term for industrial control systems with an infrastructure ofhardware, software and networking components. ICS technology includes SCADA, the network control technology used to collect and analyze data in real time. SCADA technology is used to monitor, control and optimize utilities and industrial plants.
Other industrial control systems include distributed or automatic control systems; Distributed Control System( DCS) and Industrial Automation and Control System (IACS). An important aspect of control systems is networking. These include Programmable Logic Controllers( PLC) and Programmable Automation Controllers( PAC), which are computer units used to automate, monitor and control industrial manufacturing equipment.
Furthermore, we are talking about operator consoles and remote control terminals, which are used wherever an operator terminal cannot be accommodated for space or safety reasons. In addition to the above-mentioned components, there are also intelligent components such as Intelligent Electronic Devices( IED) as well as control servers for automation technology and a wide range of different sensors.
Safety requirements for ICS systems.
The earlier machines and technical components used in the various production and manufacturing areas, in power plants and in transportation were not computerized and functionally aligned with the company's production infrastructure. The networks they were part of had no connection to other networks and were therefore safe from outside interference. In the modern manufacturing world, as these networks and their components are connected to the Internet og Things( IoT), security requirements have changed accordingly.
The security requirements are focused on multi-factor authentication( MFA) and on the principle of least privilege (POLP). The protection of the infrastructure against malware. Segmentation of networks to limit the possibilities of attack. Monitoring of traffic and analysis of threats.
