A Survey on SCADA’s Security, Concerns and Attacks

The SCADA (Supervisory Control and Data Acquisition) system is an essential component for maintaining the smooth operation of critical infrastructure systems, including water supply, transportation, oil pipelines, and electricity. Its primary function is to monitor data from vital components such as pumps, valves, and transmitters. Over time, SCADA has evolved from a stand-alone system to a highly interconnected network, resulting in several advantages, including improved efficiency and reduced costs. But that has also made the SCADA system more vulnerable to cyberattacks. Currently, SCADA security relies primarily on IT systems, which may not be enough to counter the danger and hazard from field operations. Therefore, it is crucial to evaluate the potential cyber threats associated with SCADA. This survey aims to explore the security vulnerabilities of the SCADA system, categorize the relevant threats, attacks. Finally, the survey concludes by proposing a brief outlined hybrid IDPS (Intrusion Detection and Prevention System) to detect, prevent and mitigate cyberattacks on SCADA systems.
