Leveraging the Purdue Model in Zero Trust

Securing communication between OT and IT systems is a complex task with challenges arising from legacy systems, differing security approaches, real-time demands, lack of standardization, and complex assets. The Purdue Model, provides a framework that inherently supports the implementation of dynamic identity generation, secure authentication mechanisms, and fine-grained access controls.

Strategic Implementation of Zero Trust in Industrial Control Systems

Our white paper explores implementing a Zero Trust strategy for encryption and multi-factor authentication, which significantly enhances the security of communication between Operational Technology (OT) and Information Technology (IT) systems. Learn how the Purdue Model offers guidance in relation to Identity & Access Control (IAM) for machines, including:

  • Hierarchical Segmentation
  • Security Zone Implementation
  • Device Authorization and Authentication
  • Enhanced Security Measures at the Control Level
