A Supervisory Control and Data Acquisition (SCADA) system is a type of industrial control system (ICS) that monitors and controls industrial processes and infrastructure. SCADA systems are used in a variety of industries, such as oil and gas, water and wastewater, electric power, and transportation. SCADA systems typically include three main components: a controller, a communications infrastructure, and sensors. The controller is responsible for managing the system and controlling its operations (SCADA Systems, 2018). The communications infrastructure enables the system to exchange data with other devices in the network, and the sensors provide information about the environment around the system.
Vulnerabilities associated with critical infrastructure of SCADA systems
There are many potential vulnerabilities associated with the critical infrastructure of SCADA systems. One significant vulnerability is the potential for cyber-attacks. Cyber-attacks could allow an attacker to gain control of critical infrastructure components, such as industrial control systems, and manipulate them for malicious purposes. Other potential vulnerabilities include physical attacks, such as sabotage, and natural disasters. SCADA systems are also vulnerable to insider threats, such as employees with malicious intent or employees who inadvertently introduce vulnerabilities (SCADA Systems, 2018). In order to protect against these vulnerabilities, organizations should have a comprehensive security policy and deploy robust

security measures, such as firewalls, intrusion detection systems, and cyber security professionals. Additionally, organizations should regularly audit their SCADA systems for vulnerabilities and deploy patches to address any identified issues. Finally, they should train employees on how to use SCADA systems safely and troubleshoot any issues that may arise. The role SCADA application plays in mitigating infrastructure systems risk
The role of a SCADA system is to provide a centralized interface for monitoring and controlling various infrastructure systems. By consolidating all data into a single platform, SCADA systems help reduce the risk of human error and provide a clear picture of the system’s overall performance. In the event of a system malfunction, SCADA systems can be used to quickly identify and isolate the problem, minimizing the impact on the rest of the system. In some cases, SCADA systems can even be used to automatically take corrective action in the event of a problem (Upadhayay et al., 2018). By providing detailed information about system performance, SCADA systems can help maintain infrastructure systems in peak condition and prevent potential disasters from occurring. Overall, SCADA systems play an important role in mitigating infrastructure system risk. by consolidating data and providing clear feedback on system status, SCADA systems help protect the reliability of critical infrastructure systems.
Conclusion
The vulnerabilities and roles of SCADA systems are vast and varied. They play a critical role in the infrastructure of our society, and as such, their security is of utmost importance. Unfortunately, SCADA systems are often not given the attention they deserve in terms of security, and as a result, they are often left vulnerable to attack. It is important to understand the vulnerabilities of SCADA systems so that we can better protect them from attack. Additionally, it

is important to understand the role that SCADA systems play in our society, and to ensure that they are used properly so that they can fulfill their intended function. By taking these steps, it can be ensured that SCADA systems remain secure and critical components of our infrastructure.
