On with the dawn of IIOT and the linking of legacy systems to the "cloud" what is the opinion on Edge Of Network Connectors, These are typically a small linux based computer (or windows IOT) running protocol software that hand the Siemens or Rockwell PLC data off to the Cloud. Often these are dual nic devices with one of Control network and one for the WAN connection.
But form a cybersecurity point of view Dual Homing (having a pc on two lans) is a no no as it would only take a minimal hack to turn a PC into a router and bridge the two NICS. Yada Yada Yada.
SO in practice are we all using these devices to squirt our data via MQTT or some other protocol to the cloud or are we implementing these devices and then still implementing a Firewall between the INTERNET and the EON (wan port).
Is Dual homing such a bad practice as Cybersecurity make out? Cybersecurity alwas preach that "airgap" is the bast way to protect a control system but that fine until you need data from said control systems.
