Abstract

Fifth-generation (5G) technology services, which were commercialized in 2019, not only provide voice and data communications but also have undergone significant structural changes in mobile networks to accommodate delay- and reliability-sensitive Internet of Things devices through the introduction of the latest ICT technologies, such as software-defined networks/virtualized network functions, multiaccess edge computing, and network slicing. However, this technological evolution poses new security challenges, such as creating new access paths due to complex interworking patterns, reducing security, and limiting security visibility. To address these challenges, international standards organizations, carriers, and universities are actively researching 5G security threats and security architectures. However, it is difficult for security researchers to conduct research on the development and application of 5G security technologies because of the relatively unknown nature of mobile operator networks. Therefore, in the following chapter, we analyzed the security mechanisms of 5G Core Network elements such as SDN, virtualization, network functions, and network slicing. Moreover, we examined the vulnerabilities of such security mechanisms.
