Section 1: ICS Cybersecurity Fundamentals

In part one, we will briefly recap the first edition of the book to outline what was covered and to point out the content that is still very relevant and that will be built upon in this second edition. The remainder of part one will be dedicated to discussions around a revised IDMZ architecture, resulting from many deployments, experience in the field, practice, and feedback. Part one will conclude with a deep dive into how to design for security, architecture that allows all the tools, techniques, and activities discussed in the rest of the book to be implemented effectively and easily.

This section comprises the following chapters:

• Chapter 1, Introduction and Recap of the First Edition
• Chapter 2, A Modern Look at the Industrial Control System Architecture
• Chapter 3, The Industrial Demilitarized Zone
• Chapter 4, Designing the ICS Architecture with Security in Mind
