A Programmable Logic Controller PLC is a ruggedized industrial computer running control logic, a key and vulnerable target in OT and ICS networks.
Programmable Logic Controller (PLC) Definition: A Programmable Logic Controller PLC is a ruggedized industrial computer running control logic, a key and vulnerable target in OT and ICS networks.
A Programmable Logic Controller PLC is a ruggedized industrial computer that automates electromechanical processes by reading sensor inputs and driving actuators based on programmed control logic. PLCs are core components of industrial control systems and operational technology environments, governing machinery in manufacturing, utilities, and critical infrastructure. They are frequent attack targets due to legacy protocols, weak authentication, and limited patching, as demonstrated by threats like Stuxnet.
