A Scada system takes data from various sensors connected to various instruments in a factory or any location. It collects and analyzes the data with a central computer on which the scada software is installed.
The SCADA systems are being used even in nuclear facilities worldwide. These are in use in very large plants that depend entirely upon these for efficient control and working. These can handle hundreds of thousands of input output channels.
There are many additional devices essential to make a scada system work. HMI Interfaces, controllers and various hardware are required. Various sensors analyze the data that is then sent to the central computer via communication channels.
The main computer that controls everything and has scada software installed on it is called the MTU or master terminal unit. For remotely located equipments, there are several remote terminal units that work in coordination with MTU.
Scada systems are in use in various industrial plants where these are called Distributed Control Systems. Closed loop control is more popular here and the communication is handled within local area networks.
In SCADA systems, open loop control is more prevalent though there may be some elements of closed loop control. The communications are also not just confined over LAN. The operations and controls are spread over a larger geographical area.
There are often windows in software code that are often exploited by hackers propelled by various objectives. Power infrastructure is one such vulnerable place that has to be protected from Chinese or Russian hackers. Penetration testing can minimize these problems to a big extent.
Various hardware and software equipment is used for penetration testing and all systems are monitored to find out any problem or leaks as they occur. Various equipments used in communication are also monitored for security windows. - 29939
