It's a very good article! In fact, it's the clearest explanation of what MQTT is that I saw on the Internet.
Mosquitto broker is one of the most widely-used brokers. The Pro version also offers mqtt broker high availability. I use it to secure a stable and safe connection between the system's nods. I would like to make the probability of hacking as low as possible.
What are your MQTT security suggestions? Is it safer to have an isolated network?
