I am connecting an Arduino Uno to the internet via ethernet (using the ethernet shield v2) and querying NTP time. Making requests to a NTP server is the only internet related thing it does. You can usinguse the ethernet shield useas an SD card to host data, I WILL NOT be usingdoing that. It will only be querying NTP.

I'm worried this IoT device will become a security target for my network. What attacks is it vulnerable to? And how do I secure such a low spec device?

Note: I am not worried about physical attacks, the device will be locked away.

When connecting an Arduino Uno to the internet (ethernet) what are some attacks it's susceptible to and how can I secure against them?
