OT environments often contain dense cable harnesses carrying power, sensors, and communication signals. This class teaches students how to differentiate between these wire types and locate the correct communication lines. Using systematic probing and measurement, students avoid dangerous mistakes such as connecting to power instead of data lines. This class connects to the full module by preparing students for field scenarios, where correct identification of communication lines is essential before any sniffing or exploitation attempt.

Learning Objective
Develop the ability to identify communication lines in complex OT wiring.

Training Outcomes

• Distinguish between power, sensor, and data wires.

• Apply safe probing methods.

• Recognize OT wiring hazards.

Hands-On Experience

• Use probing tools on industrial harnesses.

• Validate suspected communication wires.

• Prepare clean taps for UART exploitation.
