What is Industrial Control Systems in Cybersecurity?
A broad category of systems used to automate and control physical industrial processes, including distributed control systems (DCS), programmable logic controllers (PLC), and SCADA networks. ICS operate in manufacturing plants, chemical facilities, power generation stations, and water systems where digital commands translate directly into physical actions.
Why Industrial Control Systems Matters for Your Cybersecurity Career
ICS environments are high-value targets because compromising them can disrupt essential services and cause physical harm. Cybersecurity professionals who understand ICS protocols like Modbus and DNP3 are in short supply. Government agencies actively recruit for ICS security roles, and private sector demand is rising as industries modernize legacy control systems.
