5G systems are the next step in the evolution of mobile communication and will be a fundamental enabler for the Networked Society. This development creates new security scenarios and requires new security solutions.
As a result, there is a need for a fundamentally new, multi-actor trust model that allows more flexibility. Security for virtualized networks and services should be considered. Attack-resistance and data security must represent basic design criteria for new protocols, while security assurance and compliance have to be more verifiable and measurable. Tackling these challenges will require new tools such as network slicing, trusted computing and alternative ways of handling user identities.
