IoT World from Security Perspective

Internet of things (IOT) paradigm is changing day to day lives towards sophisticated automation and enhancing living standards of our societies. The most of ‘‘Things’’ in IoT are having limited power, storage, and computational capabilities. Therefore, data is collected, manipulated and stored in the clouds. The benefit of ‘‘anytime and anywhere’’ access of data gives rise to serious security and privacy issues and lead to many problems like exposure of user’s personal and sensitive information and loss of the trust between parties. This paper focuses on the security problems among all other challenges. As IoT is built on the basis of the Internet, security problems of the Internet will also show up in IoT. The data security and privacy concerns are very important but the potential risks associated with the IoT will reach new levels as interoperability, mashups and autonomous decision-making begin to embed complexity, security loopholes and potential vulnerability. Therefore, aim of this paper is to discuss the history and background security requirements and challenges of the IoT and its architecture. We explain and analyze the security and privacy issues related to the IoT. We conclude our paper discussing various research challenges that still exist in the literature, which provides better understanding of the problem, current solution space, and future research directions to defend IoT against different attacks.
