A framework for evaluation of cyber security challenges in smart cities

Cities are transforming to smart as various devices, technologies, services, connections, blocks, and storages are all readjusting to smart in contrast to the traditional ones. All such interconnected devices are said to be the Internet of Things (IoT) which grants the users a convenient life. At the same time, it leaves behind challenges to handle as these devices are loosely linked and the information is transmitted through the network. In this study, a review of various components forming a smart city with the challenges and factors influencing them are considered. A general objective of the study is to identify the different areas of smart city which are affected by cyber security challenges and find out the rank of each area. The data for this research is obtained from the questionnaire, experts' views and paired comparisons of the prior studies and by using the Fuzzy Analytic Hierarchy Process approach, find the weight of each factor and sub factor and their rank accordingly. Amongst the nine-factors, the "Smart Security' factor with the weight of 0.198 is the most important, and the "Smart Building" factor with the weight of 0.058 is the least significant area influenced by cyber security challenges is smart cities.
