Security Orchestration Framework for Federated Network Slicing
Network slicing is a utilitarian technology in future mobile networks that can facilitate heterogeneous network requirements of a plethora of applications over a shared physical network cost-effectively. Federated slicing, an extension of conventional network slicing, allows network services across multiple administrative domains in a seamless manner. Management of security operations in such a system is a cumbersome activity. This paper proposes a framework to simplify the security orchestration in a federated network slicing system to support efficient security management in 5G and beyond networks. Probable advantages and the potential implementation challenges of the proposed framework are discussed in the paper.
