As many of us are developing IoT devices that will be installed on corporate networks, I want to bring the titled matter to you guy's attention and see what measures can we take.
In many ways, activity of an IoT device will be drastically different from regular web browsing. Many corporate/organizations employ certain monitoring measures, intercept suspicious activities then shut down associated Ethernet ports.
This happened to one of my testing unit that is installed in an organization. It is a freezer monitoring system based on mbed. The way it works is, it constantly calls back to my servers via an Ethernet port. During certain period of time, the system works perfectly fine. During certain other period of time (mostly business hours), the device will completely go nuts. It tries to call back to my server a few times then stuck, then rebooted by watchdog timer. This goes on and on. This will usually go away during night hours and over weekends. Being intercepted by network patrolling is my primary suspicion.
Please share your experience if you had similar ones. Any thoughts and comments are welcome too.
Thanks in advance.
