IoT has the potential to change the world as it takes us to a land where our doors open by the sensors. It has been seen to be a business game-changer. The Internet of Things is the kind of network that connects everything to the net supported the protocols stipulated. It includes not only computers but also vehicles, smartphones, toys, headphones, smartwatches, refrigerators, cameras, home security systems, washing machines, fitness trackers, and many more gadgets like these embedded with sensors.
Naveen Balani defines IoT as:
Internet of things is a vision where every object in the world can connect to the internet and provide their data to derive actionable insights on its own or through other connected devices.
Uses of IoT:
Internet of things mainly used for :
- Communication
- Exchange of data
- Recording
- Smart identification
- Positioning
- Tracing
- Administration purposes
How IoT works?
Don’t know how it works? And still curious how it senses and connect to the device? It follows the four steps:
- Sensors embedded in the devices collect the data.
- Data sent to the clouds after connection via Bluetooth, Wifi, and many more.
- Cloud processed the data received by the sensors.
- IoT devices perform actions according to the instructions. After receiving a message via email or from some other means, the order can make changes.
Can IoT work without Internet?
One general belief is that IoT can not run without a wireless Internet link. Some of the devices require the internet, while others can perform its function without it. But still, it requires some means of communication to transfer information like Bluetooth. Mostly it depends on the need of the device. So, a final verdict cannot be given related to the IoT channel of communication.
What are the layers of an IoT architecture?
As long as concerned with architecture, it consists of 2 horizontal layers and 4 vertical layers, wholesome six layers.
- IoT defense and IoT network technology are used in the horizontal layers
- The vertical layers include IoT devices, gateways, platforms, and applications.
Causes of security issues in IoT:
IoT has changed the world in many ways but still have many security issues and its causes are:
- Complicated coded password
- Lack of updated mechanisms for software
- Invading privacy
- IoT bots crypto-mining
- ■■■■■■■■■ IoT devices
Can IoT devices be used in cyber attacks?
Any computer that connects to the web has some degree of harm. IoT devices are an easy target to be attacked by someone due to the presence of less advanced firmware as compared to the other operating systems. The Mirai virus was used for DDoS attacks because it could quickly hit IoT computers.
How Mirai works?
- Firstly, Mirai scans the technicalities of IoT devices.
- Then it logs into the IoT devices by employing a set of passwords and usernames.
- After this, Mirai overload IoT devices with malicious traffic.
Similarly, Stuxnet also occurred because of the malfunctioning of IoT devices. So, In this way, IoT devices are an easy target for viruses and can create cyber attacks.
What is the IoT devices’ biggest cyber threat?
Hacking the password is the most prolific threat. The hackers use automated software that allows the user to try unlimited passwords until they found the right one. Hackers can also track the IoT device due to the presence of UID that permits the user to trace each path.
Conclusion:
IoT leads us into a world in which things are not accountable. It also proves to be a disruptive technology because it helps to understand the complex choreography of the biosphere. The planet is on top of modern invention. And to use new technology, man must know its uses and harms. That’s why a few confusions have been made clear in this article.
