“The future in now” a common phrase used by the technology spearheads has now become a thing to believe in. A technology which has been in the womb for almost a decade has now started to evolve and get into a prime shape. “Internet of things” a technology which has the potential to reshape the very rules which we have been fundamentally following to live is ready to go. From environment to security, from sales to logistics and from industries to home automation, IoT has a wide range of applications which can sweep the humanity of their feet.
The question arises “What exactly IoT is?”. The Internet of Things (IoT) is a system by virtue of which different recognizable embedded devices can be connected to each other with the help of a single internet providing source. The Internet of Things mainly consists of three components they are, the things (or assets) themselves, the communication networks connecting them and the computing systems that make use of the data flowing to and from our things. An advanced connectivity of devices, systems and services can be achieved and maintained using IoT as all main components of the system are covered.
Though the technology looks all serrated, refined and ready to use but there are still many questions to be answered and many riddles to be solved when it comes to the real-time use of IoT. Questions like “What will be the data-type that will be collected?”, “Will data be collected with or without any permission?” and most importantly “Who will receive the collected data?” still needs to be answered.
One of the major parasite which still bugs the corporate world is unauthorized access by foreign body into their system and confidential data getting leaked. Technology has come and gone but nothing has been able to Barr these incidents from happening. IoT has dawned with the promise of mitigating and managing this predicament. IoT can not only connect two peripheral devices, it can also restrict and manage the access rights of an unknown body trying to toy with the network. Off course this will only work when the organization’s embedded system runs on IoT technology. To end the access control quandary and to keep the data safe, IoT spearheads are all set to use “encryption libraries” as a robust security system which will be minimizing and diminishing the liability of the data collected by the sensors which are the soul and core part of IoT technology. It also helps to combat the access related problems and maintain the three pillars of information security that is authentication, confidentiality and integrity of the data. Along with accuracy in monitoring, security and privacy protection are important issues that impact the widespread deployment of sensor networks when it comes to IoT technology. And encryption libraries gut the quandary in an appropriate manner. The methods can be different when it comes to the layer of encryption but a general encryption library system present in the IoT technology may use as many as three three cryptography layers to ensure the safety of the data involved: access control; point-to-point authentication; and public key encryption.
In this process, all network nodes share a common key that encrypts information that doesn’t allow the data to get leaked. It also has an effective mechanism which allows efficient energy consumption. This layer ensures that the third-party devices which may harm the network or steal data is kept at bay.
Point to Point authentication:
For this security layer, each sensor node interchange communication confidentially with the sensor gateway. The authentication and integrity of the data is maintained as key renewal encryption takes place and none of the involved nodes that forward information can see the data transmitted.
The sensor gateway device is the part in which the third method of encryption takes place. The sensor gateway transmits information to the Cloud by enabling each node to encrypt data using the Cloud server’s public key. The information is kept confidential by this mechanism all the way from the sensor to the Web server on the Internet.
Using the above encryption library system, data which will be generated in the IoT technology can be stored and kept secure from any malicious intent. But larger the sea of technology, the longer will be the shore of risks and vulnerabilities embedded. The list of questions still prevail that whether or not the security techniques will prove strong enough to stop the foreign body from entering the network and stealing data. The advent of a new technology like IoT off course will change the way we see the world but along with it will come a laundry of vulnerabilities and risks that may give the bubble of data thefts and misuse a larger shape.
The proper use and awareness of information security is what can help the upcoming generations to cope with this mess. The focus should be more on learning the “What” , “Where” and “Why” part of the process of securing the information rather than focusing on the “How” part. Proper guidance, learning and training can be a blessing when it comes to understanding and managing the security of data. Pro-active work has to be done when it comes to reliability and security, and training in form of simulations can work as an arrow that can pierce this target. Simulation programmes can not only widen the gauge of thinking but it can also make the professionals understand the basic concepts of information security. “The more one practices in peace, the less he bleeds in war”, there’s no harm in securing one’s base before experimenting something new. IoT is a technology which should certainly be implemented and used but the risks it may have should be judged and discussed before actual role-play takes place.
The advent of IoT may revolutionize the corporate world and other spectrum of life but work needs to be done when it comes to securing the data which will be originated and stored when IoT is being implemented and used in real-time.
