Security for anything you connect to the internet is important. Think of these devices as doorways. They either allow access to services or provides services for someone else. Doorways need to be secure — you wouldn’t leave your door unlocked if you lived in the bad part of a busy city, would you? Every internet connection is the bad part of a busy city. The thing is, building hardware that is connected to the internet is the new hotness these days. So let’s walk through the basics you need to know to start thinking security with your projects.

The easiest way to secure a device is to turn it off, but lets presume you want it on. There are many things you can do to protect your IoT device. It may seem daunting to begin with but as you start becoming more security conscious things begin to click together a bit like a jigsaw and it becomes a lot easier.
