Enhancing security and risk control in SCADA systems

The definition of SCADA is ‘Supervisory Control and Data Acquisition’. The major function of SCADA is for acquiring data from remote devices such as valves, pumps, transmitters etc. and providing overall control remotely from a SCADA Host software platform. This provides process control locally so that these devices turn on and off at the right time, supporting your control strategy and a remote method of capturing data and events (alarms) for monitoring these processes. SCADA Host platforms also provide functions for graphical displays, alarming, trending and historical storage of data. The relationship between the customer and the focus of SCADA systems by different environment such as radio links and satellite communications, fiber optic communications networks LAN, PSTN phone lines and GSM and GPRS. In this paper we introduce a new idea in the field of better control and a more secure connection to the core of each of the bases under review. In the proposed system we allocate specified address between the lines of communication and Data from each section connected to the network (client) codes. At the core in the event of non-compliance with the default code system generate alarms. SCADA systems are used to control and monitor control processes in each of the customers used these models. The advantage of the proposed method is preventing and minimize eavesdropping and sabotage and manipulation of the data to the main server. The security factor in these systems dramatically increases.
