5G network security

Nevertheless, a parallel rise in threats to system security has been noted with the rapid development of networks. As a result, cybersecurity risks have gradually changed over the past ten years. Along with the variety and complexity of system vulnerabilities, cyber threats and attackers’ methods of operation have evolved dramatically over time.

The digitization of businesses and government services has increased assault frequency, which also suggests that the consequences of cyberattacks are becoming more significant. For all network operators and the entire social structure, the confidentiality, integrity, availability, and privacy of information shared or stored by users using fifth-generation networks is essential. Additionally, many crucial IT applications including e-commerce, electronic payments, and communication with the healthcare system will be based on system security.

The 3GPP group is responsible for creating the 5G network specifications. Of fact, the 3GPP specification has a whole part devoted to network security architecture. This section’s major goal is to safeguard user connectivity, service availability, and network providers’ management of those services. It incorporates methods and security options suggested by several standards organizations (eg, IETF, ETSI ISG NFV, NIST). As a result, it can be claimed that the approaches and solutions provided are quite cutting-edge, particularly when compared to similar tactics used by earlier wireless networks. To accommodate a novel Zero Trust model, for instance, new encryption and authentication methods have been standardized, and new entities have been added to the network architecture. As a result, each information exchange between members of the same network involves members of other stakeholder groups. For instance, service providers and other infrastructure providers must adhere to certain guidelines and employ cryptographic keys.
