Abstract
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.
