SCADA stands for Supervisory Control & Data Acquisition. It’s a behind the scene scenario of the security system. It is used in all most every hardware device such as factory machines, HMIs, end devices and sensors. SCADA system works behind the devices and it displays the data, processes the information and routes the information for the employees who use devices and take important decisions. The operator pauses the operation and views SCADA by HMI and analyses the cause of the vulnerability.
