SCADA configuration system will dominate the new network security Domain

In the era of automation, SCADA systems play an important role, making automated production more efficient through remote monitoring and alerting of alarm systems. However, because of the historical reasons of SCADA system, the network security factor is less considered, so the SCADA system becomes a trend in the field of network security as more and more important equipment is improved automatically.

SCADA system becomes a trend in the field of network security

With the rapid development of computer technology, the increase of technical precision, people for industrial safety and modern automation management requirements more and more high, automation industry will need to use remote monitoring equipment, the plant in the production line of sensors collected data, back to the central system for monitoring, The data collection and monitoring System (SUPERVISORYCONTROLANDDATAACQUISITION;SCADA) is used.

SCADA Software has a wide range of applications, including petrochemical industry, wastewater treatment, power systems, food industry and other applications. Because of the different requirements of SCADA in various application areas, the development of SCADA systems in different applications is not exactly the same.

National key projects in the Water conservancy and municipal projects such as the south-to-North transfer route, a number of rail traffic SCADA is also based on foreign products, municipal industries, SCADA early scheduling market major integrators have the safety control, Tsinghua Violet, Tsinghua Tongfang, etc. The SCADA platform products which they choose in the project integration are mainly low-end configuration software, with the development of the convergence trend of the two, higher requirements for large SCADA dispatching software platform are put forward.

West gas east and Sichuan gas pipeline upstream oil and gas pipelines in the field of SCADA equipment to import brand-oriented, the major cities gas companies due to the expansion and control of the needs of the SCADA platform for the higher requirements, since 2007 public information began to believe that China's overall market growth of SCADA is about. Among them, municipal and distribution automation may be the fastest growing SCADA industry sector.

The SCADA system in power system is the most widely used, and the technology development is the most mature. With RTU, microcomputer protection device as the core, the substation control, signal, measurement, billing and other circuits into the computer system, substation Automation has been in the large-scale application in China. Power system in the field of the main suppliers of South Rui Group, Beijing Quartet, Guodian South, Xu Relay, etc., the development of products are also specific in the field of power, of which 220kV and above the scheduling system, due to the high technical threshold, currently only South Rui Technology, south Swiss relay, Beijing Quartet, Guo Dian south from, Xu Relays a few domestic suppliers can provide the corresponding products.

In the high-risk plant, the priority is to ensure the safety of plant personnel, if the plant temperature is too high or toxic gas leakage, the need for personnel to evacuate in real time, you must rely on SCADA remote monitoring, to minimize the loss. The development of SCADA system now, is not only to collect the temperature, humidity, pressure and other quantitative data, but also through the machine vision and other technologies for sound and image collection and transmission, so that monitoring personnel can better grasp the field information.

For the petrochemical industry, petrochemical in the production process has flammable, toxic, harmful characteristics, so for the pipeline monitoring system, waste water treatment monitoring system will be applied to the SCADA system, although the use of various systems of hardware and sensor modules differ, But the structure of SCADA system is to allow a variety of PLC through the communication network to upload data to the central monitoring system. The SCADA system can monitor and control the plant's problems in real-time, and can notify the managers immediately by the alarm system when there is any change in the production line environment.

In addition, with the development of China's national economy, has entered the urban mass transit development period, 2015 China has built a subway nearly 3000 kilometers, 2020 total mileage will reach 6200 kilometers. As the application of General SCADA (supervisorycontrolanddataacquisition, data acquisition and monitoring control system) system in urban rail transit industry, urban rail transit Integrated Monitoring system The Integrated Monitoring system uses the systematic method to connect the dispersed automation system into an organic whole, realizes the information exchange and the resource sharing between each professional system of the rail transportation, and also drives the SCADA comprehensive dispatching market extensively.

SCADA architecture is divided into three parts, the first part of the upper control core, that is, the central monitoring system, the second is the Programmable Logic controller (PROGRAMMABLELOGICCONTROLLER;PLC), the controller is usually located in the work site, and finally the actual execution of the equipment in the field, Including the operation of equipment, resources (including liquids, gases and electricity, etc.) and the carrying resources of the pipe and wire.

In the era of automation, SCADA systems play an important role, making automated production more efficient through remote monitoring and alerting of alarm systems. However, because of the historical reasons of SCADA system, the network security factor is less considered, so the SCADA system becomes a trend in the field of network security as more and more important equipment is improved automatically. In the future, whether it is an existing SCADA system or a vendor that is about to be introduced to a SCADA system, a holistic security solution is needed to improve productivity while protecting data and equipment.
