162 ITU‐T's Technical Reports and Specifications Considering the growing importance of this area, the FG‐SSC developed the Technical Report on “Cyber‐security, data protection and cyber‐resilience in smart sustainable cities\" to identify ways of improving cyber‐security and cyber‐resilience (defined by the Information Security Forum as the capacity to withstand negative impacts due to known or unknown, predictable or unpredictable, uncertain and unexpected threats from activities in cyberspace16). In order to protect the city from these threats, SSC shall be provided with security systems that offers protection in four dimensions: physical and environmental security (e.g., equipment security, disaster recovery prevention), system security (e.g., anti‐virus technology, host security reinforcement and operating system security), network security (e.g., gateway anti‐virus, firewall and intrusion detection) and data and application security (e.g., database encryption and database backup technologies). As a result of their complexity and significance within the city's operation, the security of some smart city services and infrastructures must be prioritized (e.g., smart grids, intelligent transportation, connected healthcare, public safety and security or wireless communications and hotspots). The information security infrastructure constitutes the technical foundation of the entire system, and as such, it provides a large number of security functions. The tasks of the information security infrastructure canters include disaster recovery, emergency monitoring, key management, security management, security evaluation and identity management. EMF Considerations SSC are based on the extensive use of wired and wireless ICTs, to provide city services in a more efficient way. Scientific research over many decades has enabled national and international health authorities to establish safety limits for human exposure to electromagnetic fields. Exposure limits vary depending on the EMF frequency and EMF source and incorporate conservative safety margins for added protection. ICTs devices and networks should be designed and deployed ensuring EMF compliance, while supporting the maximum efficiency of ICTs' utilization. ____________________ 16 https://www.securityforum.org/ Further information on the technologies and actions that can be implemented to achieve the SSC's security is available at: FG‐SCC Technical Report on “Cybersecurity, data protection and cyber resilience in smart sustainable cities”.
