Live Patching within the Purdue and Gartner Models for ICS/OT/IIoT

Most legacy OT/ICS/IIoT systems leveraged the Purdue Enterprise Reference Architecture (PERA) model, while next-generation manufacturing and utility are migrating to the Gartner IoT architecture. Navigating how to best secure connected devices within these ecosystems can be incredibly challenging.

In this whitepaper, you’ll discover:

• The security implications of the PERA and Gartner models for IIoT devices
• How organizations can strengthen their IIoT security strategy with a modernized patching approach
• How organizations can live patch OT/ICS/IIoT devices residing in the security edge, platform, and enterprise layers within the Gartner IIoT security architecture (without undergoing a system reboot)
