SCADA (Supervisory Control and Data Acquisition Systems) is an industrial control
system used to control infrastructure processes such as water treatment, power grids, gas
pipelines, airports, etc. Critical infrastructures face various vulnerabilities, such as Ransom
attacks on OT systems, physical attacks, supply chain attacks, and Legacy systems. (Cherian,
2025). Ransom attacks on OT systems involve encrypted files that disrupt physical industrial
processes, holding operations hostage until a ransom is paid. Physical attacks with cyber
motives: This method of attack is used to cause physical damage to systems and infrastructure.
Supply chain attacks: In these attacks, the attacker targets a company’s third-party vendors or
providers, such as software Developers and hardware manufacturers, to infiltrate a Target
organization’s Network and spread malware or gain access to sensitive data.(Lenaerts-Bergmans, 2023, p. 1). Legacy systems: hackers exploit outdated Hardware, software, and poor network segmentation, making them easy targets. (Cherian, 2025) .
SCADA applications mitigate these risks through real-time monitoring and automated
responses, enabling continuous monitoring of critical parameters and allowing adjustments and maintenance of every asset across the SCADA system. Segment Networks: The use of Network segmentation to create smaller subnets within the SCADA system. It helps enforce specialized access and isolate sensitive data, also adding layers of firewall and OT security checkpoints. (Security, 2025).
In conclusion, SCADA systems play a significant role in protecting critical
infrastructures from vulnerabilities. These vulnerabilities can lead to physical damage, public
safety, economic damage, National Security risks, and disruption to essential services. The role
of SCADA applications in mitigating these risks is to protect critical infrastructure.
