Securing Internet of Things

There has been many revolutions in the world – political, social, industrial etc. The invention of internet has also been considered as an important revolution in the modern world. This revolution has been so powerful that today we can’t imagine a life without internet. Speed of internet has increased. Variety of devices has increased. For instance, during the early days, it was only a desktop through which we would connect to internet. Now, we have a whole lot of devices like laptop, tablet, smartphone, smartwatch and smart appliance too.

So many devices are being connected to internet and this is leading to another revolution called Internet of Things, popularly known as IoT. While Internet has been defined as network of networks, IoT is being defined as the network of physical entities like devices, vehicles, houses and other entities with network connectivity. Another important component of IoT devices is sensor. Sensors sense the environment and notify another system using internet.

What are the implications of IoT? Take this example, which would be real in the future. You live in a house where everything is connected to internet. Your phone, TV, kitchen, air conditioner, pipes, garage, car and everything. You have gone out on a vacation. The pipe in your kitchen is leaking and it may burst soon. The sensor in your kitchen detects excess moisture. It sends a notification to your mobile informing you about a possible water leak issue in your kitchen. You get the notification and request your neighbor to come with a plumber and repair the pipe. The neighbor and plumber arrive at your home. You generate a onetime password to open the door and send it to your neighbor. The two persons enter your home and you again get a message informing you that two persons have entered your home. The pipes are repaired. The moisture level goes down and you get a confirmation message that things are in order now. You pay the plumber through a mobile wallet. Both the persons leave the house and you get a confirmation message too. All these sounds interesting, right?

That’s the future. The “smart” tag would not be only restricted to phone, watch and TV. It would stretch to everything around us. No doubt, there would be many more devices and users connected to this ecosystem. It is inevitable that when a user connects to this smart ecosystem, sensitive information would be connected too. This is where the securing IoT would have pivotal role to play. The smart eco space would need security too. As IoT would be a conglomerate of variety of services and devices, there would be innumerable entry points, and in words of a hacker, there would be innumerable opportunities to hack into the system.

Securing IoT would be challenging and interesting as well. From a current scenario of securing web applications, mobile applications and network, we would have to increase our expertise to all the devices that would be connected to internet. No doubt it would bring in new challenges. Well, security consultants love challenges!
