Understanding and Securing IoT devices

What is Internet of Things (IOT)?

As name indicates, “things” means physical objects, Collection of physical objects which are connected over the internet. In IOT, we see inter connected devices, embedded sensors or multiple other software’s which can communicate data over Wi-Fi like creating processing the user interaction and other stuff without human intervention.

We see IoT devices all around like the smart speaker in our home which can actually run the whole house just by voice commands.

We now have smart fridges washing machines lights and much more which can actually be considered as the IoT devices

Structure:

Whole IOT devices are part of four-layer infrastructure.

Layer are define as:

i. Sensor connected to IOT devices:

They can be work standalone sensing devices or can be embedded with big devices. Their work is to sense or record the data you can see the example of a smart watch which actually senses the heartbeat oxygen and keep track of them within an app.

ii. IOT gateway devices:

So all devices from layer one connected to internet by gateway devices. From this layer, sensor devices become part of network and…
