SCADA (Supervisory Control and Data Acquisition) systems are critical for managing industrial processes, including energy production, manufacturing, and transportation. However, their reliance on protocols such as Modbus, which lack inherent security features, exposes them to sophisticated cyber threats. This paper explores vulnerabilities in the Modbus protocol to design advanced SCADA-specific attack scenarios—SCADA Hijacking and SCADA Blackout. These covert attacks exploit protocol weaknesses to manipulate process parameters or halt operations while evading detection by intrusion detection systems (IDS) and human operators, representing a significant escalation in the sophistication of cyber threats. To counter these threats, we propose a novel machine learning-based defense mechanism that incorporates heterogeneous graph embeddings, combining multimodal network data such as flow-level and packet-level features. The proposed attacks and defense mechanism were rigorously evaluated using precision, recall, F1 score, accuracy and false positive rate as key metrics, demonstrating the stealthiness of the attacks and the robustness of the defense. By exposing critical vulnerabilities and presenting an advanced intrusion detection framework, this research establishes a foundation for strengthening SCADA systems against evolving cyber threats, ensuring the security and reliability of industrial control systems.

This paper will discuss some of the key features that have been implemented in the user interface component of IPL Energy’s Pipeline Control System (PCS). IPL Energy operates the world’s largest crude oil and liquid pipeline system. In 1968, IPL Energy became one of the first pipeline companies in the world to implement computer based control of its pipeline systems, commonly referred to as SCADA (Supervisory Control And Data Acquisition). Since then, the SCADA system has been continually modified and improved in order to achieve high standards of reliability, safety, and operator functionality. Unlike other SCADA systems, PCS has been developed from the ground up drawing from a wide range of experience and expertise in pipeline design, control, and operation. A brief overview of the past generations of SCADA systems will show how the user interface has evolved into the present system. The focus of the discussion will be on the Line Display, a single screen that can be used to operate a particular pipeline. The Line Display is the main operating screen used to control the pipeline and provides the operator with the current operating conditions, including operating pressures, pump statuses, and important alarms.

Critical infrastructure such as power plants, oil refineries, and sewage are at the core of modern society. Supervisory Control and Data Acquisition (SCADA) systems were designed to allow human operators supervise, maintain, and control critical infrastructure. Recent years has seen an increase in connectivity of SCADA systems to the Internet. While this connectivity provides an increased level of convenience, it also increases their susceptibility to cyber-attacks. Given the potentially severe ramifications of exploiting SCADA systems, the purpose of this study is to utilize passive and active vulnerability assessment techniques to identify the vulnerabilities of Internet enabled SCADA systems. Specifically, we collect a large testbed of SCADA devices from Shodan, a search engine for the IoT, and assess their vulnerabilities with Nessus and against the National Vulnerability Database (NVD). Results of this study indicate that many SCADA systems from major vendors such as Rockwell Automation and Siemens are vulnerable to default credential, man-in-the-middle, and SSH exploit attacks.

The advanced connection requirements of industrial automation and control systems have sparked a new revolution in the Industrial Internet of Things (IIoT), and the Supervisory Control and Data Acquisition (SCADA) network has evolved into an open and highly interconnected network. In addition, the equipment of industrial electronic devices has experienced complete systemic integration by connecting with the SCADA network, and due to the control and monitoring advantages of SCADA, the interconnectivity and working efficiency among systems have been tremendously improved. However, it is inevitable that the SCADA system cannot be separated from the public network, which indicates that there are concerns over cyber-attacks and cyber-threats, as well as information security breaches, in the SCADA network system. According to this context, this paper proposes a module based on the token authentication service to deter attackers from performing distributed denial-of-service (DDoS) attacks. Moreover, a simulated experiment has been conducted in an energy management system in the actual field, and the experimental results have suggested that the security defense architecture proposed by this paper can effectively improve security and is compatible with real field systems.

As the revolution industry 4.0 was started as well as the productivity increases, the need for data analysis increases.

Recently, as a demand for connecting Supervisory Control and Data Acquisition (SCADA) systems to open networks increases, the study of SCADA system security becomes an issue. Many researchers have proposed key management schemes for SCADA systems. However, previous studies lack the proper considerations for availability. In this paper, we build up cryptographic security requirements for robust SCADA systems. In addition, we propose a hybrid key management architecture for robust SCADA systems which supports replace protocol for availability and reduces the number of keys to be stored in a master terminal unit.

Ransomware is a malware type whose purpose is to lock and deny access to vital resources and services in the system. Like any other system, ransomware targets Supervisory Control and Data Acquisition (SCADA) and denies access to many components and data these systems collect. This represents a major threat to the systems that rely on SCADA to control the operational process. Although several studies have been conducted to address the issue of ransomware and mitigate the effect of its attacks, they approach the problem from the traditional systems perspective. That is, these solutions treat the ransomware attack on SCADA systems similar to those attacking conventional systems. This is not realistic because of the unique characteristics of SCADA systems, which are reflected in the nature and capability of ransomware attacks. Not only are data stored in SCADA nodes vulnerable to the ransomware attack, but also the data collected and shared with the other nodes. As such, traditional measures for ransomware detection become unable to deal with the attack as they assume that ransomware attacks the data at rest only. In SCADA systems, the attack model, success factors, and infection vectors of ransomware attacks are different. As such it is important to explore and understand the unique characteristics of ransomware that target SCADA systems as a prerequisite to thwart it. Therefore, this study is devoted to investigating the unique characteristics and main factors for successful ransomware attacks.
