Future 5th generation (5G) technologies are anticipated to address next generation network’s challenges and tackle the novel business requirements associated with different vertical sectors. This implies that 5G technologies will not only encompass new wired and wireless network technologies to support higher data rates, bandwidths, numbers of devices, etc., as elaborated in Chapter 2, but also need to be cohesively aligned from a technological as well as business standpoint with the different vertical sectors, for their optimized and efficient use of the network, for instance through customized network slices. Furthermore, convergence, automation and flexibility are expected to be intrinsic traits of any 5G system. The introduction of this multitude of complex new requirements and novel technologies immensely impacts the security landscape of 5G, and therefore the need to revisit its properties becomes essential.
