Introduction

Critical infrastructure systems are the physical and virtual components to society. They are the backbone of society and are so important that if they are taken out it would destroy society as a whole. That is where SCADA systems come in. SCADA is short for Supervisory Control and Data Acquisition, and it is what controls the infrastructure systems and projects them from threats.

Infrastructure systems and their vulnerabilities

Since infrastructure systems are so important to society and are physical assets, they have big targets on their backs. These systems are divided into different sectors like energy, transportation, communications, water, healthcare, and finance. According to the CISA, they state that the reason why infrastructure systems are so important is because of their “Societal Function, Economic Stability, Public Health and Safety, and National Security”. That is why their vulnerabilities need to be protected and managed. For one, physical vulnerabilities like direct attacks to the infrastructure or like a natural disaster is a big vulnerability because it has something to do with the physical infrastructure. There are also cyber-attacks that could interfere with the infrastructure’s systems with malware or ransomware. Tom Horyn also stated that supply chain attacks can also occur that compromises the systems of electrical sectors.

How SCADA systems mitigate the risks to infrastructure systems

Supervisory Control and Data Acquisition or SCADA for short is a system that is used to help mitigate the risks infrastructure systems have. One way SCADA can help mitigate risks is by giving real time monitoring and anomaly detection. With real time monitoring operators can react to potential threats as soon as possible. SCADA can also data log which is useful because it can help with the investigation of incidents after they happen. SCADA applications often include security features like firewalls along with intrusion detection/prevention systems to protect the network. Which can be helpful to stop and detect cyber-attacks.

Conclusion

In conclusion infrastructure systems are responsible for how society is operated now and without them society would crumble. That is why SCADA was created so that said infrastructure systems can be protected from their vulnerabilities.
