I’m not talking about putting the fridges behind a firewall or a VPN.
In most factories I’ve worked in (if there’s any outside connection at all), you would connect devices to a PLC with 2 network cards. The PLC’s other network card goes to a server (that’s again, ideally not on an exposed network at all).
In this case, if your server was compromised, and someone tried to compromise the PLC, they’d need to safety sign it (and often physically touch it to set it to run). You just can’t hack a motor or something in a factory from afar if it’s networked correctly.
It’s a LOT more than just a firewall in proper OT setups.
PLC: lol, fuck you, bro, I’m still in run mode. And if you stick your knife in the lock again because you’re too lazy to find a screwdriver I’m gonna break the tip off.
Temping every fridge in grocery stores is a pain in the ass 🤷
Y’all realize these commercial fridges with temps have been a thing well over a decade right?
You can have stuff on automation networks and not expose them to the internet
Yeah dude, the point of the meme was definitely vlans 🤦
Also, totally nobody ever got past a vpn/firewall 🤦

Yeah dude, grocery stores all around the world running physical dmz’s in house 😂👌👍🤡
delusional stuff
Yes.
This is the price they pay if they don’t wanna pay for either good design for their network or someone to manually take temps 🤷
Yep, every day occurrence that we sold totally spend millions of dollars on.
Nice clown makeup!
