“…The connection between the control center and field sites is performed using a communication subsystem that allows remote access to field sites for the purpose of diagnostic and failure repair. Furthermore, the communication subsystem connects the control center with SCADA partner plants [1]. Layer 2 also contains a supervisory network that connects the SCADA master terminal unit (MTU) server, historian server, engineering workstations, HMI server and consoles, as well as communication devices such as routers, switches, and modems.…”

“…S UPERVISORY control and data acquisition (SCADA) systems are considered a type of industrial control systems that allows users to monitor and control industrial processes locally or remotely through sensors and actuators [1]. SCADA systems allow industrial organizations to operate critical infrastructure by controlling and monitoring real-time data and processes of various sectors, such as electric generation, oil, gas, and manufacturing plant systems.…”

“…Cloud-based SCADA systems can improve the performance of traditional SCADA systems by enhancing features such as quality of service (QoS) for computing environments, reliability, flexibility, availability, efficiency, and proper configuration, maintenance, and reduction of technical and industrial costs. Mirjana, S. et al [1] provided an overview of the main scenarios regarding the migration of SCADA systems to the cloud, with a special attention paid to the cyber security factors such as authentication, access control, intrusion detection, and privacy. However, real-time data transmission over the Internet, and remote access features of the new SCADA systems have made these systems more susceptible to various cyberattacks and have initiated many security holes for potential attackers, who can exploit the systems vulnerabilities to inject worms, spyware, and viruses.…”

<p>Supervisory control and data acquisition (SCADA) systems allow industrial organizations to control and monitor real-time data and industrial processes. Moving SCADA systems to the cloud environments can improve the performance of traditional SCADA systems by enhancing features such as storage capacity, reliability and availability, security measures, as well as reducing technical and industrial costs. However, cloud cyberattacks are rapidly increasing, posing a major challenge to such type of systems. In addition, these cyberattacks still remains scattered across many research, and much of published research on cloud-based SCADA systems has been focused on narrow sets of attacks. Thus, this research provides a survey and an analysis of the most common cybersecurity attacks and challenges that cloud-based SCADA systems might experience. It also conducts a security risk assessment of the analyzed attacks. Finally, it proposes the existing suitable detection and prevention techniques to mitigate the impact of cyberattacks on such critical control systems.</p>

Specific intrusion detection systems (IDSs) are needed to secure modern supervisory control and data acquisition (SCADA) systems due to their architecture, stringent real-time requirements, network traffic features and specific application layer protocols. This article aims to contribute to assess the state-ofthe-art, identify the open issues and provide an insight for future study areas. To achieve these objectives, we start from the factors that impact the design of dedicated intrusion detection systems in SCADA networks and focus on network-based IDS solutions. We propose a structured evaluation methodology that encompasses detection techniques, protected protocols, implementation tools, test environments and IDS performance. Special attention is focused on assessing implementation maturity as well as the applicability of each surveyed solution in the Future Internet environment. Based on that, we provide a brief description and evaluation of 26 selected research papers, published in the period 2015-2019. Results of our analysis indicate considerable progress regarding the development of machine learning-based detection methods, implementation platforms, and to some extent, sophisticated testbeds. We also identify research gaps and conclude the analysis with a list of the most important directions for further research.

Məqalədə neft-qaz sənayesinin monitorinqi və idarə edilməsində geniş istifadə olunan buludəsaslı SCADA (ing. Supervisory Control and Data Acquisition) sistemlərinin təhlükəsizlik məsələlərinə baxılmışdır. Ənənəvi SCADA sistemləri çox bahalı, qeyri-çevik, miqyaslanması çətin olduğundan məlumatların toplanması, ötürülməsi və emalında çoxsaylı problemlər yaranır. SCADA sisteminin tətbiqlərinin bulud mühitinə köçürülməsi xərclərin azaldılmasına, miqyaslanma imkanlarının yaxşılaşdırılmasına, sistemin səmərəli idarə olunmasına, etibarlılığın yüksəlməsinə və resurslarla bağlı problemlərin həllinə imkanlar yaradır. Məqalədə buludəsaslı SCADA sistemlərinin təhlükəsizliyinə mane ola biləcək mövcud boşluqlar göstərilmişdir. Buludəsaslı SCADA sistemlərində təhlükəsizlik tədbirlərinin görülməsi və risklərin qiymətləndirilməsi aktual məsələlərdəndir. Bu məqsədlə buludəsaslı SCADA sistemlərinin istifadəsində meydana çıxan təhlükəsizlik problemləri və risklər analiz edilmiş və bunların müəyyən qədər həllinə komək edən təkliflər verilmişdir.
