Security and privacy issues have developed critically important with the fast expansion of multi-agent systems. Most network submissions such as pervasive computing, grid computing and P2P networks can be viewed as multi-agent systems which are open, anonymous and dynamic in nature. Such characteristics of multi-agent systems introduce vulnerabilities and threats to providing secured announcement. Industrial systems always prefer to reduce their operational expenses. To support such reductions, they need solutions that are capable of providing stability, fault tolerance, and flexibility. One such solution for industrial systems is cyber physical system (CPS) integration with the Internet of Things (IoT) utilizing cloud computing services. These CPSs can be well-thought-out as smart industrial systems, with their most prevalent applications in smart transportation, smart grids, smart medical and eHealthcare systems, and many more. These manufacturing CPSs mostly utilize supervisory control and data acquisition (SCADA) systems to control and monitor their critical infrastructure (CI). For example, WebSCADA is asubmission used for smart medical technologies, making improved patient monitoring and more timely decisions possible. The concentration of the study obtainable in this paper is to highpoint the security challenges that the industrial SCADA systems face in an IoT-cloud environment. Conventional SCADA organizations are already lacking in proper security measures; however, with the integration of complex new constructions for the future Internet based on the concepts of IoT, cloud computing, mobile wireless sensor networks, and so on, there are large issues at stakes in the security and deployment of these classical systems. Therefore, the incorporation of these future Internet perceptions needs more research effort.
