Security Issues on Internet of Things in Smart Cities

Introduction

In a day to day life, many researchers are focusing on IoT in smart cities. It invites researchers to concentrate on simplifying engineering challenges. IoT includes recognition, locating, tracking, monitoring and management of devices in a reliable manner. There are numerous security challenges which include network security, authentication, security-side-challenge attacks, security analytics, interface protection, delivery mechanism and system development and so on. The idea of the Internet of things was first proposed by Kevin Ashton, co-founder of Auto-ID centre at MIT in his presentation made to Procter & Gamble (P&G) in 1999. He discovered to link objects with an RFID tag. The concept of IoT evolved as the wireless Internet became widely developed, embedded sensors grew in worldliness. The Internet of Things (IoT) has the power to modify our world. The infrastructure of IoT encompasses interconnected objects, people, systems and information resources. These objects require intelligent services to allow them to process information of the physical and virtual world or hybrid of two and react accordingly. The intelligence of Things is necessary to pervade analytics into our systems (Wu, Chiang, Chang & Chang, 2017) and applications because collecting data alone is not enough.

IoT architecture can be considered as a global network infrastructure of a three-layer system consisting of IoT enabling technologies, IoT software and IoT applications and services. These layers are a collection of numerous active physical objects, actuators, sensors, specific IoT protocols, cloud services, communication layer, users, developers and enterprise layer. IoT has immense applications and consists of many technical and non-technical disciplines such as physical connections, manipulation of data, application interfaces, regulatory issues, and cybersecurity
