# 6G Use Cases and Scenarios: A Comparison Analysis Between ITU and Other Initiatives
## 8 Security Aspects of the Proposed 6G Use Cases  
ITU mentioned security (together with resilience) as one of the 6G capabilities. According to xxx, security is related to the necessity to secure data, networks, platforms, and devices against cyberattacks. Future 6G networks enhance security and resilience since they must be secure by design. Although security properties must be guaranteed in all six ITU usage scenarios, in the Integration of Sensing and Communication and Massive Communication, the need for guaranteeing high security levels is stressed, due to the huge number of involved systems and devices with different characteristics. ITU also mentions some potential technologies to improve 6G security, such as Blockchain, differential approach to privacy, quantum technology, and Physical-Layer Security (PLS) technologies. According to the 6G-IA initiative, future systems will be more intelligent, powerful, and dynamic. In this context, trust is a crucial aspect to consider in conjunction with security (e.g., in terms of authentication, authorization, and non-repudiation). Trust is also related to functional and non-functional criteria, such as the approach to data management and performance,respectively. Since we will assist in a powerful convergence of digital, physical, and personal environments, a lot of data can be collected. The efficient control of data integrity and security is crucial. 6G IA remarks on the need for network and service security, since 6G will be characterized by high complexity and fragmentation. The potential approaches are evidence, such as zero-touch micro-segmentation and slicing, together with distributed AI/ML functions and models. The disruptive strategies and concepts for 6G security are also described beyond classical approaches, such as virtualization, softwarization, deception, or moving in terms of target defense, a holistic approach during the entire lifecycle, and \"security as a service\" based on cloud technology. Finally, 6G IA considers hardware security, AI/ML-assisted security, and the impact on professional skills as important topics to be considered carefully. The HEXA-II initiative considers the social aspects of security, especially in terms of privacy risks, since the 6G will provide connectivity and services anywhere for everyone. Privacy and security are important requirements to be considered both for Terrestrial Networks (TNs) and Non-Terrestrial Networks (NTNs). For example, services for public safety during big events are important, such as for managing situations of rising emotion, facial recognition, etc. HEXA-II also identifies the privacy/security, reliability/availability, and service continuity concepts as the main constraints and challenges for the next 6G. According to NGA, the regulatory requirements at the national and regional levels are to be satisfied by the next 6G, especially in terms of national security and safety. In addition, customer security and privacy have to be considered by designing services and applications. Trust, security, and resilience are some of the most important objectives of the Next G Alliance activities. Most identified use cases require a high level of security and resilience. In the case of the Online Cooperative Operation among a Group of Service Robots (SOBOTs), security is needed to manage data from healthcare and critical applications. If field robots are used in hazardous environments, they need to use the output provided by AI/ML algorithms to identify the best decision to adopt. In the case of public safety applications, security is crucial for monitoring and managing data acquired in a smart city environment, while for synchronous data channels, it supports authenticity. Finally, in the case of healthcare in-body networks, and personalized user experiences, the use of data needs to be secured and managed by adopting a privacy-oriented approach. NGMN also considers security, trust, and privacy as crucial elements to be considered by future technologies in several use cases.
