SG17: Security SG17 coordinates the security-related requirements across all ITU-T SGs. It works very closely with other SDOs and deals with a broad range of standardization issues in areas like cybersecur- ity, security management, security architectures, and identity management. A focus area of this SG addresses the security architecture requirements for IoT, smart grid, smartphones, SDN, cloud networking, web services, analytics, social networking, mobile financial systems, IPTV, and healthcare teleservices. There is much more information in Chapter 8 on the processes the ITU-T uses to develop recom- mendations and specific details on those in SG15 recommendations related to timing and synchronization. 4.1.1 ITU-D The ITU Telecommunication Development Sector examines telecommunication questions as they relate to countries that are underserved by telecommunications services. The ITU-D SGs conduct surveys and provide opportunities for member states and sector members (associates and academia) to exchange views, present ideas, and share experiences. The ITU-D is responsible for sharing final reports, guidelines, and recommendations based on the input received from study group members. There are two study groups under ITU-D: SG1: Enabling environment for development of telecommunications/ITCs SG1 focuses on the national telecommunications/ICT policy, regulation, and technical and stra- tegic aspects of telecommunications to drive benefits for developing countries. These policies and strategies also cover infrastructure requirements to support broadband services, cloud com- puting, Network Functions Virtualization (NFV), consumer protection, and future telecommu- nication services that contribute to sustainable growth. SG1 covers the following: Economic policies and methods of determining costs of services Policies and strategies to provide telecommunication services to rura
