Supervisory Control and Data Acquisition, otherwise known as SCADA, is a control system that is designed and used to collect data from industrial equipment. Some industries such as large oil and gas operations or even public utilities use SCADA systems. When it comes to vulnerabilities within the critical infrastructure systems, SCADA is able to provide modern connections of direct and radio to further communication requirements, the monitoring system used is telemetry. Communication between software and hardware has also developed. SCADA protocols are also compact and are able to send information to master stations. SCADA vendors can use applications such as a Human Machine Interface (HMI), that is linked to SCADA systems databases to provide intricate diagnostic data, trending information, and detailed schematics for certain machines or sensors to have an overall view for system maintenance and operations. Most commonly, SCADA systems are used in alarm systems, whenever a vehicle needs gas for example, messages and emails are sent to the SCADA clients. Cities that are wanting to become more ‘smart’, can use SCADA for control over heating and cooling systems, power grid management and light traffic patterns. City managers are able to have more control over their operations with the use of SCADA. The use of SCADA ensures the mitigation of risk in vulnerabilities of infrastructure systems. It allows venders to have more control and information over system management and modern smart manufacturing for hardware and software.
