The future belongs to smart devices. There will be 28 billion connected devices in the world by 2021, and 15 billion of those will use machine-to-machine protocols — which means they’ll talk to each other.
In fact, we are already surrounding ourselves with smart devices, and many of them lack the security features your computer has. This means they can be hacked. So when your home gets smarter, you too should be smart about it and start thinking about how to make it safe.
