Episode notes
ICS Transformation
- Industrial control systems (ICS) are shifting from isolated networks to interconnected systems, driven by cloud computing and automation.
- This transition, part of Industry 4.0, aims to optimize efficiency by enabling data flow and cloud-based control decisions.
Diverse OT Devices
- Operational technology (OT) devices vary significantly across industries, from blast furnaces in steel foundries to robots in auto manufacturing.
- These devices are being digitized to improve efficiency and safety, but this also introduces new vulnerabilities.
Lights-Out Plant
- Grant Geyer mentions a meatpacking plant with a fully automated, "lights-out" facility run entirely by robots.
- This example demonstrates a fully transformed stage in the transition from air-gapped to cloud-connected OT environments.
