Is 5G a security risk?

Summary

As 5G networks roll out across enterprise and consumer use cases, the question of whether the technology introduces new security exposure has become impossible to ignore for operators and their customers. Twimbit's founder and managing director joins Nokia's global head of pre-sales and advanced consulting services for cloud and network services to unpack what actually changes with 5G from a security standpoint.

Building an appropriate trust model for 5G networks takes center stage, recognising that the technology's distributed, virtualised, and software-driven architecture creates a fundamentally different attack surface compared to previous generations. That shift has implications for how operators design security into the network from the outset rather than treating it as an add-on.

Beyond architecture, the operational side of security comes into focus: what best practices look like when managing security operations at scale across a modern telco network, and how operators should balance investing in proactive threat detection against maintaining strong reactive incident response capabilities across radio, core, and edge network layers.

• Practical guidance on structuring security operations teams and processes

Is 5G inherently more of a security risk, or does the answer depend entirely on how operators design and operate their networks?
