- onion2k 9y agoMany things shouldn't accept inbound connections, but outbound is really useful. A manufacturer being able to collect data from devices to monitor their health means they can have an engineer onside before a problem takes the equipment down, and the manufacturer is able to learn what happens in the lead up to certain problems, and so on. Most modern industrial equipment has this sort of telemetry data collection. You don't hear about hacks very often. A lot of manufacturers seem to do a pretty good job of security (or of covering up hacks).
- crocal 9y agoTelemetry is encrypted end-to-end, using proprietary stacks, networks and protocols. Very hard to exploit. Not impossible but would require a lot of insider knowledge to make it practical.
- tetha 9y agoYeah, outbound connections should be fine. Monitoring data, heartbeats or alerts especially. It's not too hard to encrypt it securely. And even if it's leaked, it shouldn't be too critical in general. The sink of this data should be a regular server, so you can secure and update it properly.
- crocal 9y agoI am ready to bet that this was not supposed to be connected to Internet, but it was just more convenient to use this « workstation » for multiple use, and so hook it up to the company office network and automation network. Cyber security is mostly a matter of policy and control, rather than technical issues.
