IoT Security Fundamentals: Hardware, Software and Radio Security

What is IoT – IoT stands for Internet of Things. The Internet of Things (IoT) is the interconnection and network of various devices formed by connecting any physical device (Vehicle, Tube Light, Thermostat etc) to the internet for sharing and exchanging the data.

How does any physical device become capable of getting connected to the Internet?

To make this happen, we simply use prototyping board such as Arduino, Raspberry Pi, Beaglebone etc or embed a chip into the device which makes the device capable of connecting to the internet for sharing and exchanging data.

Hope the definition and the concept behind IoT is clear.

Other names for IoT – IoT has other names as well. Few of them are –

  1.   M2M (Machine to Machine)
  2.   Internet of Everything
  3.   World Size Web
  4.   Skynet

Components of IoT – IoT is not just a network of physical device connected via Ethernet cable or wirelessly to the internet. It involves following components –

  1. Physical Object – The device which will be connected to the internet. Example – If you want to connect a fan to the internet, a fan is a physical object.
  2. Sensors – A device which detects or measures a physical property and records, indicates, or otherwise responds to it.  Example – Temperature sensor for sensing the temperature.
  3. Actuators – A component that is responsible for moving or controlling a mechanism or system. Example – If you want to turn off the fan, you will issue a command to turn off the fan. The physical device which turns off the fan is termed as actuator.
  4. Cloud Service Provider – Cloud service for connecting to the cloud. Example – AWS, Azure, IBM Watson etc.
