Industrial Cybersecurity

Overview of this book

With industries expanding, cyber attacks have increased significantly. Understanding your control system’s vulnerabilities and learning techniques to defend critical infrastructure systems from cyber threats is increasingly important. With the help of real-world use cases, this book will teach you the methodologies and security measures necessary to protect critical infrastructure systems and will get you up to speed with identifying unique challenges.Industrial cybersecurity begins by introducing Industrial Control System (ICS) technology, including ICS architectures, communication media, and protocols. This is followed by a presentation on ICS (in) security. After presenting an ICS-related attack scenario, securing of the ICS is discussed, including topics such as network segmentation, defense-in-depth strategies, and protective solutions. Along with practical examples for protecting industrial control systems, this book details security assessments, risk management, and security program development. It also covers essential cybersecurity aspects, such as threat detection and access management. Topics related to endpoint hardening such as monitoring, updating, and anti-malware implementations are also discussed.

Chapter 5. The Purdue Model and a Converged Plantwide Ethernet

In this chapter, we will be taking a closer look at the Purdue Enterprise Reference Architecture (PERA), or Purdue model for short. The Purdue model is an industry best practice and a widely adopted concept model for ICS network segmentation and is used extensively to explain ICS architectures.

This chapter also includes an explanation of the Converged Plantwide Ethernet (CPwE) architectures. CPwE is a collaborative effort between Cisco and Rockwell Automation to publish ICS network architectures that cohere to industry best practice design and security recommendations. The architectures are tested and validated for functionality and performance by both companies.

The following topics will be covered in this chapter:

  • The Purdue Enterprise Reference Architecture
  • ICS Purdue model adoption - CPwE
  • ICS network segmentation
  • ICS network levels/layers
  • The CPwE industrial network security framework
