IoT vs OT / ICS / SCADA – CIA Plus Safety
IoT vs OT / ICS / SCADA – CIA Plus Safety IoT : smart everyday devices, like cameras and smart plugs. OT (Operational Technology): computers that run machines in factories and power plants. ICS = industrial control systems; SCADA watches many sites; a PLC is a small computer next to a motor. In OT,

What this card says
What each one is
IoT: smart everyday devices, like cameras and smart plugs.
OT (Operational Technology): computers that run machines in factories and power plants.
ICS = industrial control systems; SCADA watches many sites; a PLC is a small computer next to a motor.
Why OT is different
In OT, safety comes first, next to confidentiality, integrity and availability.
A normal IT scan can make old OT devices hang or reboot.
Real incident
On 23 December 2015, attackers caused power cuts at Ukrainian electricity companies.
About 225,000 customers were affected (as reported). They started with spear-phishing on the IT network.
Defence
Ask the OT owner first. Use approved, read-only tools.
Keep IT and OT networks separated.
| World | What it is |
|---|---|
| IoT | Cameras, smart meters, MQTT sensors, "smart" plugs |
| OT / ICS | Plant / warehouse control – PLC, HMI, SCADA |
| SCADA | Supervisory view + remote commands over a wide area |
