Abstract

 
In Industries, it’s always look forward to reducing their operational cost and their Critical infra structures. Therefore, companies search for solutions to reduce their cost and ensure the system efficiency. One of that solutions is the use of a Cloud computing system which offers the advantage of integrating CPSs such as SCADA systems. This paper proposed a cost effective, simple, reliable and secured Cloud SCADA system. The proposed Cloud SCADA System based on secured nodes was implemented, which connects each other through VPN channel “encrypted’’ to ensure the isolation of our system form external attacks. The remote terminal unit (RTU) also connected to master terminal unit (MTU) through unit encrypted VPN channel, so in our system, when the end user need to connect to MTU the firewall of our system protect on MTU from un-recognized end point users. Comparing the cost of our system with pervious work, it’s lower than Arduino + WI-FI method by five times and 13 times lower than Raspberry-PI method. Also comparing with other server options the proposed server is easy for using, available for adding new components and also has high security.
