I also do programming, especially embedded programming. Now it's called the "Internet of Things." Fortunately, the standards for security and reliability haven't changed that much relative to the history of embedded programming.
I am concerned that some customers are attaching things to the Internet of Things which should not be on the Internet of Things. Like cows. "Why can I not ping my cow?", one farm asks me. "Why did you put a cow on the Internet?!", I reply. They do not know, but Compliance says "because compliance," so now there's a cow on the Internet.
I am also concerned that NB-IoT is also going to be a thing in the near future. It's so cheap! It's so cheap, you can put cellular radios on all the things! Please do not do this. All the things do not need to run LTE stacks on energy harvesting SoCs forever and ever.
