SCADA (supervisory control and data acquisition) SCADA (supervisory control and data acquisition) is a category of software application program for process control, the gathering of data in real time from remote locations in order to control equipment and conditions. SCADA is used in power plants as well as in oil and gas refining, telecommunications, transportation, and water and waste control. SCADA systems include hardware and software components. The hardware gathers and feeds data into a computer that has SCADA software installed.
In Figure 1, we depict an example SCADA system configuration used to monitor and. control wind power electric generation. The six items in Figure 1 instrumental to SCADA security are (1) the use of wireless bridges to. communicate with wind turbines, (2) the connection of a wireless bridge to Ethernet hub/switch, (3) the connection between the SCADA control center Ethernet switch/router and 3rd party and. administrative networks through a firewall, (4) modems attached to the main SCADA control.
