Internet of Things
Maybe have you asked yourself, why this concept that lastly is in fashion. Nowadays, we hear terms like IoT, Revolution 4.0, and something else.
Internet of Thing known by its acronym “IoT”, this does refer to the next generality:
- Devices that allow perceiving, informing or acting in a specific environment.
- Communication protocols and hierarchy between devices.
- Basic information analysis.
- Information storage services.
- Visualization of data in real-time.
What is IoT?
So IoT is one of the most important technologies of the Fourth Industrial Revolution. It occurs when any object is connected to the internet and through sensors, it is given the power to interpret sensations from the environment to transfer data through a network. This quality of receiving and transmitting information makes objects “communicate with each other”, generating and sharing valuable data for different purposes.
Even today we live in a world where there are more devices connected to the Internet of Things than human beings. Juniper research
Combined with other technologies from the Fourth Industrial Revolution, such as data science and artificial intelligence, these connected devices allow the collection and analysis of information, as well as the execution of an action to facilitate specific tasks and learn from different processes.
for example, nowadays, not only phones and tablets are connected internet to. A growing network of objects is also accessing the Internet: locks, refrigerators, televisions, exercise wristbands and much more.
How it works IoT?
the internet of things consists of physical devices that can connect to the internet and communicate with each other via the cloud, In general, it means adding special sensors to physical objects like washing machines, heaters, refrigerators, watches, and just about anything else.
the best way to understand a concept is to do a lot of examples. I’ll do that.
Imagine for a while a vending machine, use sensors to monitor their stocks and send information to the owner. This serves to avoid running out of existence.
Other devices, can receive information and then, to perform an action. for example, a smart lock receives the opening signal from you and consequently unlocks a door.
Another example can be. Imagine that the alarm sounds to wake you up and while you are going to take a shower your coffee maker starts to cook a coffee for you, after receiving the alarm signal. Incredible, do you think so?. I want one for me. and so on, there may be more and more examples.
In general, smart technology helps things (Devices physical) work better, more efficiently and in sync.
How do IoT devices connect between them?
IoT allows devices that can be connected to a network to interact with each other according to the data that is sent. Devices use the cloud to communicate and connect over the Internet using Wi-Fi, a mobile data connection (3G or 4G), or Bluetooth.
IBM estimates that a typical family home will have about 500 Internet-connected devices by 2022. And that in a single house! previous estimates indicate that 20 billion devices were connected to be used in IoT over 2020.
Implications of the IoT for security and privacy
In late 2016, cybercriminals launched major distributed denial of service (DDoS) attacks, causing a disruption in internet services that affected many companies, including Amazon, PayPal, Netflix, Spotify and Twitter.
To do this, the group behind the attack exploited the security weaknesses of thousands of IoT devices, allowing them to be hijacked and turned into originators of Domain Name System (DNS) requests. Essentially, it flooded traffic to the DNS hosting provider, Dyn. Gartner.com-books-digital.
While IoT devices can enrich your life in certain ways, they can also pose a threat.
When evaluating its safety, the whole is only as strong as the weakest of the links. You probably have antivirus software on your computer and your iPhone (or Android device), but what about your smart fridge? A non-secure IoT device is enough for hackers to access your entire network.
Unfortunately, any device capable of connecting is susceptible to malware.
Beyond leaking personal data, IoT poses a risk to critical infrastructure, including electricity, transportation and financial services.
Computers, phones, and tablets are more secure than other devices, not just because you probably have an antivirus installed on them, but because they receive regular updates. These updates often fill security holes and solve other problems. When it comes to IoT gadgets, companies don’t always dedicate resources to providing updates.
Fortunately, some companies are already working to provide us security and support for our IoT devices.
