Supervisory Control and Data Acquisition

Supervisory Control and Data Acquisition (SCADA) is an automated control system for large-scale, geographically dispersed industrial processes. Its core function involves collecting field data via Remote Terminal Units (RTUs) and Programmable Logic Controllers (PLCs) and enabling monitoring and control via a Human-Machine Interface (HMI). As a critical component of Operational Technology (OT), SCADA is extensively used in critical infrastructures. In risk management, SCADA security risks directly impact physical safety and operational continuity. International standards such as NIST SP 800-82 Rev. 2 and the IEC 62443 series provide comprehensive security frameworks to prevent cyberattacks that could lead to major industrial accidents.

Applying SCADA in risk management focuses on establishing a security architecture aligned with international standards. Key steps include: 1) Asset Inventory and Risk Assessment, guided by IEC 62443-3-2, to define security zones and conduits. 2) Defense-in-Depth Control Implementation, following NIST SP 800-82, which includes strict network segmentation to isolate OT from IT networks. 3) Continuous Monitoring and Incident Response, using industrial protocol-aware Intrusion Detection Systems (IDS). A major utility implementing these measures can increase its compliance rate to over 95% and reduce potential network intrusion incidents by approximately 30%.

Taiwan enterprises face three primary challenges in securing SCADA systems. First, Legacy Systems: Many systems are outdated and cannot be patched. The solution is implementing compensating controls like network segmentation (priority: within 90 days). Second, the IT/OT Cultural Clash: IT prioritizes confidentiality, while OT prioritizes availability. This can be overcome by forming a converged IT/OT governance committee (priority: within 60 days). Third, a Talent Shortage. Enterprises should engage expert consultants for assessments and training, initiating this process within 30 days to build internal capabilities systematically.
