SCADA stands for Supervisory Control and Data Acquisition. It's a computer-based system that monitors and controls industrial processes and equipment by gathering and analyzing data in real-time.Supervisory Control and Data Acquisition (SCADA) systems are used for controlling, monitoring, and analyzing industrial devices and processes. The system consists of both software and hardware components and enables remote and on-site gathering of data from the industrial equipment.
The networked SCADA systems are also known as third-generation systems. The networking and communication of present SCADA systems can be done using the WAN system through data lines or phones. The data transmission among two nodes can be done with the help of Ethernet or Fiber-optic connections.
Distributed SCADA systems are called second-generation systems. The distribution of the control functions can be done across numerous systems by connecting with a local area network. The control operations can be performed by sharing real-time data & command processing.
IoT SCADA systems are fourth-generation systems. In these systems, the system’s infrastructural cost is reduced by implementing IoT through cloud computing. Maintaining as well as integrating these systems is easy as compared with others.
At present, SCADA networks are used extensively in current industries to check & examine real-time data, industrial processes can be controlled, communicate with devices. So SCADA systems are essential for industrial organizations because these systems include hardware & software. So, SCADA security is also essential in industries.
