5G unlocks unprecedented applications previously unreachable with conventional wireless connectivity to help enterprises accelerate digital transformation, reduce operational costs, and maximize productivity for the best return on investments. To achieve its goals, 5G relies on key service categories: massive machine-type communications (mMTC), enhanced mobile broadband (eMBB), and ultra-reliable low-latency communication (uRLLC).
With the growing spectrum for commercial use, usage and popularization of private 5G networks are on the rise. The manufacturing, defense, ports, energy, logistics, and mining industries are just some of the earliest adopters of these private networks, especially for companies rapidly leaning on the internet of things (IoT) for digitizing production systems and supply chains. Unlike public grids, the cellular infrastructure equipment in private 5G might be owned and operated by the user-enterprise themselves, system integrators, or by carriers. However, given the growing study and exploration of the use of 5G for the development of various technologies, cybercriminals are also looking into exploiting the threats and risks that can be used to intrude into the systems and networks of both users and organizations via this new communication standard. This entry explores how normal user devices can be abused in relation to 5G’s network infrastructure and use cases.
