Secure end-to-end 5G cloud deployments

The virtualization and automation of network functions have enabled cloud-based deployments of mobile cores and open Radio Access Networks (RAN). While 3GPP has standardized 5G to be the most secure generation of cellular technology, there is an evolving threat surface as RAN and Core deployments move to the cloud. Concurrently, new attack vectors are exploiting vulnerabilities in cloud architectures and software to increase risk. This panel brings together leading 5G cybersecurity experts from mobile network operators to discuss their insights for securing 5G RAN and Core cloud deployments. Key topics for discussion include existing 5G security standards, cloud security, zero-trust architectures, IoT security, open RAN security, and network slicing.
