A working plant network on the wall of Aaron Crow's studio. Siemens and Rockwell PLCs, HMIs, switches, firewalls, sensors and remote access, laid out by Purdue level and tested one task at a time. You get the honest take and the details.
The OT Wall is laid out the way a plant should be: enterprise on one side, the process on the other, and every path between them crossing a firewall and an industrial DMZ.
We start it flat on purpose. One subnet, everything talking to everything, the way too many sites still run. Then we segment it, monitor it, and lock down remote access one episode at a time.
Guests join in person or remote over the lab's own isolated network. The lab never touches anything but itself.
Monitoring taps every cell by SPAN and TAP, side by side.
No slides. Each episode will take one real job a plant team does and run it on live gear.
Install the gear, cable it into the cell, bring it up from factory defaults.
Build the config on camera, from baseline hardening to the episode's task.
Push it until something gives. Bad change, wrong rule, rogue laptop on a port.
Find it, fix it, and say what it took. Then the honest verdict.
Where we can, we share the details: what we set up, what broke, and how we fixed it.
Twelve episodes planned, in build order. Each one picks up where the last one left the wall.
The map, the bill of materials, unboxing.
Both cells on one subnet. See how much is reachable.
Managed vs unmanaged, L2 vs L3, hardening.
Segment to the addressing plan, break it, fix it.
Same traffic both ways, and what each one misses.
Default deny, built from the flows the process needs.
Two cells on the same subnet, both reachable.
Open-source monitoring vs a commercial sensor, same wire.
What belongs in it and what does not.
A guest programs the PLC from outside, the right way.
Logic and config changes, caught or missed, then restore.
A live water process behind everything built so far.
OT Range runs on donated and loaned equipment. If your product belongs in a plant, it belongs in this lab.
