Explanation
Air Gap: The concept of an air gap (physical isolation) was the cornerstone of security for many legacy OT systems. These systems were not connected to the internet or corporate networks, making them less susceptible to remote attacks. Legacy Protocols: Older OT systems often used proprietary or serial communication protocols, not designed for internet connectivity. Implicit Trust: Within the isolated environment, there was often an assumption of trust among the connected components.
