This study will focus on Internet of Things (IoT) based security issues. IoT is persuasive in nature and accomplish user’s requirement through the intelligent gadgets like sensors, actuators and physical computation devices. IoT is not just about interconnecting embedded devices or gadgets to the Internet, it is about lifestyle. This study aims at identifying existing and future security issues within IoT by performing a comprehensive literature review of peer-reviewed articles from the last 5 years. The review identifies the IoT privacy and security issues from a different perspective and highlights which security issues have been discussed most by the researchers in past and present as well as highlighting future security issues within IoT. The outcomes are presented and highlighted through graphical representation. In the past, confidentiality, integrity and inter-operability and in present, authenticity, data privacy and security issues have been most widely discussed. In future, integrity, confidentiality and authenticity issues will have more significance and need to be addressed in order to successfully implement and achieve benefits from IoT.
