Discussing the role of lab firewalls
The lab firewalls can be used for routing, inspecting, logging, and monitoring traffic. As an example, they will be crucial to getting the interconnectivity between IT and OT. The IT firewall should be configured with a static route into the industrial network:
Figure 19.14 – IT firewall static routes to the industrial network
On the other hand, the OT firewall uses a default route (route for the 0.0.0.0 subrange) to the IT firewall:
Figure 19.15 – OT firewall default route to the enterprise network
You will learn that these firewalls are versatile tools in setting up scenarios and environments for your experiments and testing exercises throughout this book.
