Internet Of Things (IOT) Overview


Internet Of Things:

The internet of things (IoT) is a computing concept that describes a scenario where every day physical objects are connected to the internet and can identify themselves to other devices or processes, via an IP address.

In particular, “things” might communicate autonomously with other things and other devices, such as sensors in manufacturing environments or an activity tracker with a smartphone. 
IoT has evolved from the convergence of wireless technologies, micro-electromechanical systems, microservices and the internet. 

This convergence has torn down the walls between operational technology and information technology, allowing unstructured machine-generated data to be analysed for insights that will drive improvements. 

Consumer IoT took another revolutionary path, either by becoming connected – for example, speed sensors on a bike – or being newly invented. In other instances, such as in healthcare, things have been there but not widely used, such as patient health status.

As many businesses look to adopt the Internet of Things (IoT) by connecting internet-enabled devices to assets and relay that information back to key decision makers, the need for a platform to store, manage and analyses all of this data is increasingly important.
The good news is there are lots of options in the market, with all of the big players in public cloud (AWS, Azure, Google Cloud Platform and IBM) providing IoT platforms, as well as smaller pure-play options for more industrial IoT (IIoT) uses. All the big players promising the easiest, smartest platform available.

How things communicate:

From the operational perspective, smart devices can communicate via several models, such as device-to-device This is where two or more devices can directly communicate with each other through various network protocols, including internet protocol (IP), Bluetooth, Z-Wave or ZigBee. This type of protocol is typically used with low data rate requirements such as light bulbs, light switches and door locks.

Please refer below flow to understand how Things communicate.


Another way of communicating is by device-to-cloud. An IoT device connects directly to an internet cloud service to exchange data. It typically uses wired Ethernet of Wi-Fi connections between the device and the IP network. This type of connection is used by Smart TVs.

Device-to-gateway is a method where the device connects through an application-layer gateway as a conduit to reaching a cloud service. The gateway provides security and other functionality such as protocol translation. A typical use is a smartphone running an app to communicate with a device, such as a fitness band, and relay data to a cloud service.

Finally, back-end data sharing refers to a communications architecture that enables users to export and analyse smart object data from a cloud service in combination with data from other sources. The back-end sharing architecture allows the data collected from a single IoT device data streams to be aggregated and analysed.

Smart devices have used internet protocol, IPv4, that is running low on available IP addresses. This is being replaced by IPv6 that will provide sufficient IP address possibilities for the foreseeable future.

IoT Industries:

Several environments within the three groups of consumers, governments, and ecosystems will benefit from the IoT. These include:
  • Manufacturing
  • Healthcare
  • Insurance
  • Banks
  • Transportation
  • Defense
  • Agriculture
  • Infrastructure
  • Retail
  • Logistics
  • Oil, gas, and mining

IOT Security:

While security considerations are not new in the context of information technology, the attributes of many IoT implementations present new and unique security challenges. Addressing these challenges and ensuring security in IoT products and services must be a fundamental priority.Users need to trust that IoT devices and related data services are secure from vulnerabilities, especially as this technology become more pervasive and integrated into our daily lives. Poorly secured IoT devices and services can serve as potential entry points for cyber attack and expose user data to theft by leaving data streams inadequately protected.

The interconnected nature of IoT devices means that every poorly secured device that is connected online potentially affects the security and resilience of the Internet globally. This challenge is amplified by other considerations like the mass-scale deployment of homogenous IoT devices, the ability of some devices to automatically connect to other devices, and the likelihood of fielding these devices in unsecure environments.

As a matter of principle, developers and users of IoT devices and systems have a collective obligation to ensure they do not expose users and the Internet itself to potential harm. Accordingly, a collaborative approach to security will be needed to develop effective and appropriate solutions to IoT security challenges that are well suited to the scale and complexity of the issues.
