Security and Privacy in IoT

Abstract

The Internet of Things (IoT) plays a remarkable role in our modern daily life. With the use of IoT our daily life has become easier and more dynamic. The IoT covers almost all fields which include home automation, office automation, healthcare, sports, industrial applications, and transport, Smart Cities, agricultural, Smart Energy and the Smart Grid, etc. Therefore this technology requires security management and the privacy control over the user data which is in cloud. Security in IoT is the technology area concerned with securing connected devices and networks in the Internet of Things environment where we have a number of devices connected over the internet with IP addresses. So many devices, sensors, things that we are wearing or using, the things that we are interacting with that we will not even sense it in future. The IoT enables development of helpful tools and technological partners to resolve security issues which may occur in future. Due to the small size of modern CPUs, the possible features of IoT and its applications are almost unlimited. IoT devices are connected to the internet, so they are vulnerable to the same kinds of cyber-attack that can affect the user’s personal and commercial information. Through IoT the user is connected to a number of devices for gathering and controlling information. Therefore protecting consumer privacy of information has become difficult as the IoT becomes available to all involved. A number of devices are connected to different kinds of devices and this increase in connectivity and data collection results in less control of privacy of information to the public. Both control of data and control of the different devices that are connected has become a major area of concern in the modern age of internet access. So maintaining control over the data and devices while maintaining privacy is of more concern as control can be lost if someone hacks into the smart phone or computer. Control can be lost when more and more companies collect data about users connected to the internet. Everything that we search, and all of our online activities, are being tracked by many companies that provide us with services for their data-mining purposes and for improving user experience over the IoT. But sometimes these activities breach user security and privacy of data.
