(155c) Assessing Cybersecurity Risk in Industrial Internet of Things (IIoT) Applications

The advent of the Industrial Internet of Things (IIoT) within the chemical industry has the potential to expose control and safety systems to significant cyber security threats. These include:

• Exposure of the ICS to untrusted external connectivity
• Poor controls on generic IIoT Gateways or Edge Devices
• Weak Cloud Security
• Control conflicts and process upset derived from the advent multiple control schemes

This presentation will review the results of a cybersecurity risk assessment of 4 common IIoT applications and recommend secure architectures and associated security controls appropriate to each.
