IoT Threat-Over the past few years, Internet of Things has become a hot topic of conversation among professionals. It’s a conviction that not only has the potential to impact how we live but also how we work. But the question is: “What is Internet of Things”? Furthermore, How does IoT benefit us in our daily routine life? How secure are these physical devices? And how is it going to impact us? There are a plethora of questions being discussed every day.
Let’s begin with understanding few things: With the evolution of internet, more and more devices are connected to the outside world, thanks to the inexpensive and widely available internet; more devices are being built with wi-fi features and sensors, technology costs are reducing tremendously and adoption of smartphones is sky-rocketing. All these factors are pushing IoT to the next level.
The underlying concept of Internet of Things is connecting physical hardware with an ON and OFF switch to the internet. More specifically, it is an ecosystem of physically connected objects that are accessible through the internet i.e. objects that have been assigned an IP address and have the ability to collect and transfer data over a network without manual assistance. Now, imagine the list of things that can become an IoT device. For example, consumer appliances such as lights, refrigerators, curtains, washing machines, toaster etc. In addition, industrial things can be PLC’s, jet engine of an airplane or street lights of a building or a city—almost anything else you can think of. According to Gartner, there are already more connected things than people in the world. Gartner Analyst calculates that around 8.4 billion IoT devices were in use in 2017, up 31 per cent from 2016, and this will likely reach 20.4 billion by 2020, which means the size is already big and getting bigger as we are moving on.
Now, to answer the other question about how this can impact you. Nowadays, people are more connected than ever before and smart technologies have provided them with adequate opportunities to stay online and upload their personal data to the cloud. For instance, calculating the number of steps you walk in a day has never been so easy, but now smart phones are tracking and uploading your information regardless of intervention. There are many other examples like what if you book an appointment on your calendar and the calendar in turn notifies the conference room manager as well as turns on the lights according to your meeting schedule. What if your alarm clock wakes up you at 6 am and then notifies your coffee maker to start brewing coffee for you? What if you are on your way home and your car could have access to your mobile phone and before reaching, your car notifies the power switch to turn on the air conditioner. Therefore, IoT can be applied to numerous things which can help us in improving efficiency and reduce waste.
