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, and the need to revisit cybersecurity posture is critical to all manufacturing and utility organizations.

Fortunately, there are a number of security measures, including live patching, that organizations can employ to keep their devices and their IIoT data secure.

Modernizing Your Approach to IIoT Security

TuxCare, a global leader in live patching as well as security patching for end-of-life (EOL) operating systems, databases, and critical software libraries, developed with whitepaper to help organizations strengthen their IIoT security approach.

In this whitepaper, you’ll gain an understanding of:

• The security implications of the PERA and Gartner models for IIoT devices
• Best practices for IIoT security and compliance as well as threat modeling
• 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)
• Extending end-of-life (EOL) support for Python and PHP applications used in IIoT devices and applications
