A CYBER SECURITY ONTOLOGY FOR SMART CITY

Smart city is an intelligent and interconnected city that aims to enhance the quality of living of its people by using information and communication technology (ICT). However, the intrinsic inter-connectivity makes it highly vulnerable to security attacks. Therefore, it is essential to build a robust architecture that not only offers smart city services but also satisfies its security issues. This paper presents an integrated layered architecture for smart city security named ICADS. Moreover, two semantic models of ICADS are proposed as ontologies, namely OntoICADS and Secure-OntoICADS, to deal with the dynamicity and security of smart city. Secure-OntoICADS provides formal description to four major elements of security i.e. vulnerability, attack, security requirement, and security mechanism. Additionally, to validate their adaptability, ontologies have been mapped to different smart city applications.
