Toward Zero Trust Security IN 5G Open Architecture Network Slices

Developing trust in 5G network slicing is an important issue since as mobile networks evolve the number of internal components, network functions, and the use of virtualized elements increase. The current security practices that are based on a perimeter/defense-in-depth cybersecurity approach are proven to be ineffective to address the current and future cybersecurity challenges because they assume that everything on the inside of a network is trustworthy. One promising approach of growing significance in the telecom security sphere is the Zero-Trust (ZT) security model. This paper opens a new research direction for implementing a real-time ZT framework that enables trustworthy deployment and secure management of network slices in 5G open architecture.
