Chapter 3: The Industrial Demilitarized Zone
In the previous chapter, we discussed a high-level overview of the Industrial Control System (ICS) network architecture. Within that high-level discussion, we touched on the concept of the Industrial Demilitarized Zone (IDMZ). In this chapter, we will be taking a deep dive into the IDMZ. We will be going over the general design, concepts, and technologies used to create the IDMZ and will explore areas that have changed since the IDMZ was first discussed in the first edition of this book.
In this chapter, we'll cover the following topics:
- The IDMZ
- What makes up an IDMZ design
