Class Description

Operational Technology (OT) is hardware and software that controls physical processes like factories and power plants. These processes are far more efficient when networked services monitor, control, and automate them, but also are exposed to network attacks. The primary OT protocols, such as Modbus and DNP3, are decades old and lack security features. This class covers the risks of OT installations and how to secure them.

No experience with programming or hardware is required. It's recommended to have familiarity with networking at the Network+ level.
