And it's also surreal to trust any of these cheap things for actions or data just based on a credential implanted to them at production.

Software has to assume the other side might be lieing. "Take nobody's word for it" as the royal society's motto goes.pic.twitter.com/2Su8O4bF1b

Yes. And we start to have the means to find out whether someone lies. A measured temperature is never 20.00C in a straight line over time.

Whole new kind of software, model and verify data in real time, looking for

The concept of
#maldata, deliberately injected fake data, isn't common. Most such systems not designed to deal with malicious actors.1 reply 0 retweets 1 like -

Faulty wiring, bad soldering and careless interpretation of datasheets has the same effect and is common enough...

Sure. But I'm arguing that the assumption that data from other parts of a distributed system may be bad will become normal for
#iot systems.1 reply 0 retweets 2 likes -
It already is normally assumed... But you're right that maliciously bad data is an increasing threat outside of traditional bad sources...
