Abstract
Technologies which enhance the quality of everyday lifestyle are increasing rapidly. During their initial development, Internet and network-based services were not built by taking cyber security measures into consideration. The cost of this is still being paid to this day. Nowadays, there are certainly clear need for cyber security requirements for almost all Internet and network-based systems. Several kinds of such systems are normally connected together in unprecedented ways in smart cities. This in fact will complicate the security requirements that should be considered when building smart cities. Yet, the studies on security requirements in smart cities remain to be one of the fields that needs further exploration. This article explores the essential cyber security requirements in smart cities by considering various previous research studies in the field. On top of that, several other recommended security requirements will be introduced as a response to the gaps that continues to be predominating the field.
