Secured cloud SCADA system implementation for industrial applications

Abstract

The proposed Remote SCADA System (RSS) is a smarter, faster and more reliable way to control high power machines and monitor their sensors, data, and failures. The proposed system focuses mainly on building our own complete SCADA software and not using open-source SCADA software. The proposed RSS can use unlimited number of added Remote Terminal Units (RTU) nodes and each of them can handling unlimited number of input/output and can be used under different operating systems like Windows and Android. Using RSS all machines can be monitored and controlled by a single click from anywhere at any time. By doing this a real-time response from RSS system can be achieved. It’s mainly based on standard communication techniques between remote nodes and single server-side application that talk to each node with its own ID and modify its instant database. So that every time accessing this web application, a real-time access to these nodes data and a virtual control room controls each General Purpose Input/Output (GPIO) in the selected node can be gotten. When a new event is happened in server-side program, it will be broadcasted to all related. On RSS there are two main points to deal with, the request latency and security of the system. This paper studied how the system latency and security are improved to obtain the needed values. The proposed RSS is a very secure program which have 4 security levels; authentication, authorization, RSA and CBC encryption system. Also, the encryption algorithms used in RSS are RSA and CBC block cipher encryption system. It is mixed way to prevent any attacker from breaking the cipher. First of all, RSA generates the public and private keys, and then CBC generates its Initialization vector and a random encryption key. Then a special function sends all of these keys encrypted with a pre-stored token in the data base and node memory which varied from node to another. Finally, node generates its private key from loaded public key. With this combination the speed of symmetric encryption system and the security of asymmetric encryption system can be achieved. On the other hand, the level of security firewalls needed to be Brocken by the attacker to brock the cipher is increased. The proposed system achieved low cost comparing with reported work; it is lower than Arduino + WIFI method by five times and 13 times lower than Raspberry-PI method. The proposed system is applied in educational systems, where it is used for teaching unlimited number of students Online.

Development of an IoT-Based SCADA System for Monitoring of Plant Leaf Temperature and Air and Soil Parameters

“…The recent applications of IoT-based SCADA cover many areas, such as plant monitoring [17], electricity [33,34], electric power plants [35][36][37][38], industrial applications [39], wastewater treatment plant [40], telecommunication system [41], traffic control [42], education [43], oil production [44], and Smarthome [45]. The literature survey of the IoT-based SCADA systems is summarized in Table 2, where the field of application, RTU hardware, protocol, and MTU software and hardware are shown.…”

SCADA Systems With Focus on Continuous Manufacturing and Steel Industry: A Survey on Architectures, Standards, Challenges and Industry 5.0

“…The Better domain knowledge, which resulted from aforementioned research, provided a strong basis for building simulation environments that are proposed in form of various SCADA testbeds [57], [177] able to visualize the stages of a cyber attack [178], and a toolbox for attack simulation to train and test the security mechanisms [179] These simulation environments and tools have provided methods for analyzing various types of threats such as stealthy attack [180], or new family attacks such as Heuristic Inference Attacks [181], related system vulnerabilities as well as exploring new ways to protect critical infrastructures such as Blockchain [182] and implementation of AI algorithms for intrusion detection systems (IDS) such as Support vector machine (SVM) access to Modbus TCP protocol [183] Furthermore, numerous solutions have been proposed, enhancing SCADA security within various domain of implementation, such as cyber attacks on cloud SCADA systems [184], end-to-end encryption between SCADA and Open PLC [185], fuzzing SCADA protocols in smart grids [186],…”

Integrating Industrial Appliances for Security Enhancement in Data Point Using SCADA Networks with Learning Algorithm

“…An integration process of cloud security using SCADA is carried out for industrial application where a greater number of remote units are installed in communication path. Since more units are installed, if any SCADA network fails, then other networks will carry out the entire operation with high security features [19]. However, a bigger number of remote units increase the cost of a communication unit inside the infrastructure medium.…”
