Security Protective Measures for the Ubiquitous City Integrated Operation Center

With the diffusion of ubiquitous technologies, many city facilities that are closely related with our daily life are being combined with IT technologies. As a result, various IT services running on the separate network are also being integrated into a city-based service. However, serious problems can occur in terms of the stability and reliability of the u-City (ubiquitous city) service, if the security factor is not fully considered and applied while developing new IT services that will be integrated into u-city projects. In particular, if any security incident occurs at the u-city integrated operation center (uCIOC), which is designed to collect, analyze and combine the city-related information, and manage and operate the city functions, serious chaos could occur due to a paralysis of the city functions. This paper analyzes the characteristics and security threats against uCIOC, and proposes measures to protect against or counter these threats.
