The expression smart city, as it is often used in English speaking countries, could be translated to Hungarian as liveable city, where the primary goal is to make the lives of residents easier by improving both the physical and digital infrastructure. Yet the concept comes with various, previously hidden risks. Hackers today are no longer pimpled teens hiding away in basements, but hacktivists who could easily paralyze the smart city’s complete public transport system in protest against, let’s say, free passes for seniors. However, there is no security without analysis, says T-Systems Security Strategist Arthur Keleti in an interview following his presentation at ISACA about cities of the future, cybercrime and the reasons why we don’t fear the internet enough.
