Industrial Control Systems – Operational Technology

Would you know if a device on your Operational Technology (OT) network was compromised on its way from the factory to you? Or if a contractor inadvertently installed some malware that didn't activate until months later?
This scenario presents just such an attack on the OT network—one of the existing devices on the network is intercepting and modifying SCADA traffic. It could be producing false measurements, or be sending commands to an unsuspecting device on behalf of the SCADA Server!
