Major security flaw detected in 5G core network slicing design

Security experts have found a hole in a key element of next-generation networks.

Network slicing will be one of the critical drivers of 5G, as it allows private wireless networks to be constructed. But according to AdaptiveMobile Security, there is a significant security flaw in its architecture of 5G and that of virtualised network functions.

The vulnerability allows data access and denial of service attacks between different network slices on a mobile operator's 5G network, leaving enterprise customers exposed to malicious cyber attacks.

Network slicing allows a mobile operator to divide its core and radio network into multiple distinct virtual blocks that provide varying amounts of resources and prioritisation to different traffic types. One of the most innovative aspects of 5G, network slicing, will let operators offer portions of their core networks for specific vertical customer use cases, such as automotive, healthcare, critical infrastructure and entertainment.
