Security Fundamentals in Internet of Things

Abstract

With growing number of smart devices per person and at each individual’s homes, it is estimated that the number of objects connected to the Internet is higher than the number of people connected to it. This trend is only gaining popularity with more and more objects now interfacing with the Internet. This in-turn creates a network of smart devices that are closely integrated with the physical world, thereby providing increased efficiency and economic benefit. This is collectively termed as Internet of Things - IoT. Just like all other technology enhancements, IoT also brings up threats and security issues that need to be considered before application of the technology in various fields.
This document provides a framework that describes the threats that will be seen at each level of IoT and the major issues needed to be addressed before implementing a secure system.
