A Way to Access SCADA System via Satellite Channel and its relevant Security Trends

SCADA systems have been playing important roles for industrial automation and processing, as the results the productions can be produced in minimal time with more efficiency and profitability. Mainly, the whole industrial production is carried through various connected sensors or field devices, which may configured in local area network (LAN)/Wide area network (WAN). In previous two decades, wireless based communication gained popularity and the SCADA industries (such as oil, gas and water) also accepted and deployed their production through the use of wireless media. To be more advanced, the SCADA systems are also required to access the remote networked devices that may located at various places in the World over wireless links, thus the best solution is satellite communication. Satellite transmission will provide an easy, faster and efficient access to, monitor and control the geographical networked remote devices from the central location or central station, which also a main goal of this study. This study proposes a satellite based communication facility for SCADA water station, moreover security issues that mainly linked with satellite transmission are also considered and relevant protection mechanisms are suggested.
