Security for 5G

5G networks based on standard technical specifications from the Third Generation Partnership Project (“3GPP”) continue to be the most widely adopted and secure wireless cellular technology in existence. As increased bandwidth, higher data rates, and a surge of new devices and connections have made managing network security more complex, 5G Americas has provided nearly annual updates around the topic of security in wireless cellular networks. ‘Security for 5G’ is the latest update, building on prior work and focuses on evolving 5G security considerations.

This white paper addresses emerging challenges and opportunities, making recommendations for securing 5G networks in the context of the evolution to cloud-based and distributed networks:

  • 3GPP security enhancements in 5G
  • 5G security considerations
  • Zero-trust networks
  • 3GPP Release 16 security enhancements
  • Security for 5G vertical segments, such as transportation, manufacturing, and critical infrastructure
  • Supply chain security
  • Open RAN security

Additionally, the white paper provides insight into securing 5G in private, public, and hybrid cloud deployment models. Topics such as orchestration, automation, cloud-native security, and application programming interface (API) security are addressed. The transition from perimeter-based security to a zero-trust architecture to protect assets and data from external and internal threats is also discussed.
