I ran across this article about IoT security the other day
The US Needs to Get Serious About Securing the Internet of Hackable Things
I find articles like this frustrating for the simple fact everyone keeps talking about security, but nobody is going to do anything. If you look at the history of humanity, we've never been proactive when dealing with problems. We wait until things can't get worse and the only actual option is to fix the problem. If you look at every problem there are at least two options. Option #1 is always "fix it". Option #2 is ignore it. There could be more options, but generally we pick #2 because it's the least amount of work in the short term. Humanity rarely cares about the long term implications of anything.
I know this isn't popular, but I'm going to say it: We aren't going to fix IoT security for a very long time
I really wish this wasn't true, but it just is. If a senator wants to pretend they're doing something but they're really just ignoring the problem, they hold a hearing and talk about how horrible something is. If they actually want to fix it they propose legislation. I'm not blaming anyone in charge mind you. They're really just doing what they think the people want. If we want the government to fix IoT we have to tell them to do it. Most people don't really care because they don't have a reason to care.
Here's the second point that I suspect many security people won't want to hear. The reason nobody cares about IoT security isn't because they're stupid. This is the narrative we've been telling ourselves for years. They don't care because the cost of doing nothing is substantially less than fixing IoT security. We love telling scary campfire stories about how the botnet was coming from inside the house and how a pacemaker will kill grandpa, but the reality is there hasn't been enough real damage done yet from insecure IoT. I'm not saying there won't ever be, there just hasn't been enough expensive widespread damage done yet to make anyone really care.
In world filled with insecurity, adding security to your product isn't a feature anyone really cares about. I've been doing research about topics such as pollution, mine safety, auto safety, airline safety, and a number of other problems from our past. There are no good examples where humans decided to be proactive and solve a problem before it became absolutely horrible. People need a reason to care, there isn't a reason for IoT security.
Someday something might happen that makes people start to care. As we add compute power to literally everything my security brain says there is some sort of horrible doom coming without security. But I've also been saying this for years and it's never really happened. There is a very real possibility that IoT security will just never happen if things never get bad enough.
