Integrating Industrial and Business Networks

Presented by

Damon Small - NCC Group, Carl Eshelman - SCADAfence

About this talk

The Purdue Enterprise Reference Architecture (PERA) was developed in the 1990’s. The associated Purdue Reference Model describes the relationship between end-users, business networks, control systems networks, and the security boundaries between them. In the decades since its creation, the manner in which computing resources are used in industrial settings has changed dramatically. As a result, the lines between Operational Technology (OT) and Information Technology (IT) continue to blur, and are often being broken outright. The speaker will share his observations of this evolution through a real-world case study, and provide insight into how successful organizations can embrace these changes in a manner that improves efficiency without increasing risk unnecessarily. The target audience is professionals who manage or integrate with Industrial Control Systems (ICS) networks, and the speaker will provide examples of why the discussion should not focus on the concepts of OT vs IT, but rather the careful utilization of data. Specific topics include: - History of the Purdue Model - Limitations of the Model - Economic forces driving change - Technological forces driving change - Case study of modified L3/L4 integration - Convergence of OT/IT
