IOT based Security and Privacy issues in Smart Cities

The security issues in Internet-of-Things (IoT) have received a lot of attention from both industry and academia. Several surveys targeting various IoT-related subjects have been proposed for this goal. This study, on the other hand, focuses solely on security vulnerabilities in IoT. In this regard, we have presented a review by first exploring the fields of smart cities and then the possible security leakages. This seeks to make IoT research easier by bringing together, comparing, and contrasting disparate research contributions in terms of security. Several studies have focused on the area of research on privacy and security to highlight the risks within smart cities. This study has analysed the associated challenges within smart cities and, after analysing the landscape of fundamental technologies in smart cities, we have aligned this review towards the security issues. The most prevalent applications and challenges are discussed. This paper provides an overview of the IoT in smart cities along with operational mechanisms, Important technologies along with potential applications of these applications are evaluated to describe the major research issues.
