PLC
Programmable Logic Controller — A ruggedized industrial computer that directly controls physical machinery and processes, such as opening a valve or starting a motor, based on sensor input, forming the lowest-level control layer in most ICS environments. PLCs often run on decades-old firmware with limited built-in security, making them a persistent soft target in OT attacks.
