8 Guidelines for the SSC ICT architecture

These guidelines provide with specifications the SSC ICT architecture regarding the following
aspects:
 Security and Privacy requirements: they are specified under the corresponding [ITU SSC‐0090]
Technical Report on Smart Sustainable City Cybersecurity, data protection and cyber resilience
in smart sustainable cities

 Quality requirements: these are the minimum set of quality requirements have to be specified
for each SSC ICT architecture's subsystem and for the overall architecture performance. Section
5.1.4 defined a set of principles for the SSC ICT architecture, some of which are totally quality‐
based (i.e., manageability, fault‐tolerance, scalability, etc.)

 Guides for each subsystem: the above modular analysis returns the complex nexus of a SSC.
However, most of the architecture components can be standardized and the assignment of
standards to these components is presented in the following (Table 2):
