Abstract
A smart city is developed, deployed and maintained with the help of Internet of Things (IoT). The smart cities have become an emerging phenomena with rapid urban growth and boost in the field of information technology. However, the function and operation of a smart city is subject to the pivotal development of security architectures. The contribution made in this paper is twofold. Firstly, it aims to provide a detailed, categorized and comprehensive overview of the research on security problems and their existing solutions for smart cities. The categorization is based on several factors such as governance, socioeconomic and technological factors. This classification provides an easy and concise view of the security threats, vulnerabilities and available solutions for the respective technologies areas that are proposed over the period 2010-2015. Secondly, an IoT testbed for smart cities architecture, i.e., SmartSantander is also analyzed with respect to security threats and vulnerabilities to smart cities. The existing best practices regarding smart city security are discussed and analyzed with respect to their performance, which could be used by different stakeholders of the smart cities.
Highlights
The concept of smart cities is very vast as its vision encompasses management and organization of the whole city through embedded technology
An Internet of Things (IoT) testbed for smart cities architecture, i.e., SmartSantander is analyzed with respect to security threats and vulnerabilities to smart cities
Though smart cities promise growth in economy, and better banking and business services, but this component of a smart city is most vulnerable to security threats as it can be attacked for personal financial use
Summary
The concept of smart cities is very vast as its vision encompasses management and organization of the whole city through embedded technology. As the concept of smart cities is still developing, the need to identify the core requirements of information security in various technologies is important. The issues of information security needs to be addressed for a better economic development of a smart city. The requirements of of ideally secured and reliable smart cities need to be recognized considering most of the technologies, specially focusing on IoT, cloud computing, real world user interfaces, smart sensors, smartphones, semantic web etc. The objective of this paper is to survey pivotal problems and the solutions in practice regarding information security in a smart city in the light of key influencing factors.
