OK as a security sort of dude there was a very interesting study released (note this study is rather illegal in most countries so do not attempt), which showed once again how insecure devices on the internet are and frankly how many of them are already pwn3d, but from a IoT view there are a couple of really interesting things to note. First the second most used Web Server is Allegro RomPager which is an embedded device web server, IoT isn’t coming, its already here.
Worth the read, and remember to write secure code!!
