Introduction Critical infrastructure relies on industrial control systems (ICS/OT) to ensure continuous, safe, and reliable operation. In recent years, there has been a sharp increase in cyberattacks targeting these systems, exploiting unique characteristics such as legacy components, vendor connectivity, and complex supply chains. Many mistakenly believe that improving cyber resilience in OT environments is similar to the process of strengthening resilience in IT environments. This perception stems primarily from a lack of sufficient understanding of the OT domain and an adherence to historically rooted IT-centric assumptions. In this article, I will examine the fundamental gap between cybersecurity concepts originating in the IT domain and the unique requirements of industrial control systems, and present a practical security approach based on processes, safety, and operational continuity, not solely on technology.
