Ugh. None of the industrial protocols like Bacnet or modbus have any built in security so this looks pretty bad

- nikomen 7y agoAgreed. These protocols are difficult to secure. However, it shouldn't be difficult to isolate devices from the internet. Isolation doesn't protect against inside attackers or an external use from causing trouble after getting into the network. It should be obvious these devices shouldn't have access to the internet.
- statictype 7y agoRight. Even internally they should ideally be on their own subnet.
