That's designed to protect smart devices from attack and protect other systems on the network from compromised smart devices. This tried and true technique is known as network segmentation. Network segmentation, simply places untrusted devices on a network of their own, where they have no access to trusted systems. In the context of embedded devices, it might look something like this. We have our standard corporate wired and wireless networks that have laptops, desktops and servers connected to them and then a separate network hanging off the firewall that contains embedded devices used to control an industrial process.
