A wireless engineer sat in a parking lot, connected to a plant's crane anti-collision network, and had everything he needed to stop the cranes inside 20 minutes. Nobody inside the fence ever knew he was there.

In this episode of Protect It All, host Aaron Crow talks with Scott McNeil, Industrial Network and Security Architect II at Global Process Automation (GPA), about the part of the OT network most plants never look at: the airspace. Scott has spent more than 20 years in networking and wireless, the last ten of them entirely in OT, and he sits in the integrator's seat, working across every manufacturer's gear without a product to sell.

The conversation starts where most plants actually are: one flat network, off the shelf gear on the floor, and no budget. Scott's argument is that the low hanging fruit costs time and effort, not money, and that a stable network is the foundation for everything security asks for later: segmentation, inventory, monitoring, then a firewall between OT and IT. He walks through war driving your own plant, why a hidden SSID is not security, the wild west of industrial wireless protocols, wireless that was abandoned in power plants years ago and is still on the air, and where wireless earns its place.

The second half is about vendors and access. Do not take the vendor's word for it, ask the questions before the gear ships, and treat every third party connection as your own exposure. Scott's rule for remote access is simple: this is my house, vendors connect on my terms, every session logged, with an approve or deny button before anyone gets in. Aaron adds the zip tie in the fan story, a backup switch that had silently failed months earlier and nobody knew until monitoring went on, and the two close on shrinking the wireless footprint that leaves your site and on Scott's podcast, The Industrial Wi-Fi Shop.

In this episode, you'll learn:

Why a stable network comes before any security project, and what to fix first

How to war drive your own plant and what a passive scan of your airspace tells an attacker

Why hiding the SSID and relying on obscurity is not a control
