In a recent hearing in the House of Representatives the question was asked whether it is feasible to create one set of security standards for all IoT devices. One of the panellists said yes and the other two said no.
I was a bit puzzled by this. I would guess that it would be extremely difficult to have one standard for so many different types of products (refrigerators, cars, HVAC units, ...). I was wondering if someone familiar with the discussion could summarize the arguments for answering the question in the affirmative.
