The key motivation for
this work is that future smart services (e.g. IoT applications) will have
competing and perhaps conflicting networking performance requirements. These
services will also require flexible and agile deployment. 5G networks, an
essential component of future virtualized infrastructures, deal with this issue
– in part – by relying on network slicing. To define a network slice, one has
to consider the allocation of resources – both in the radio and core parts – of
the 5G network to form a logical entity where a service could be deployed.
Network slicing has emerged as a key-enabler for proving heterogeneous
services. It takes advantage of the virtualization elements of future
networking infrastructures where multiple services can be hosted on the same
physical infrastructure.

This talk will give a
quick overview of network slicing with emphasis on 5G core networks. It will
also discuss the requirement for network slice isolation and different methods
that were proposed to implement it. Finally, an overview of our research group
ongoing work on mitigating Distributed Denial-of-Service (DDoS) attacks using
slice isolation. Our approach is to tackle slice isolation as a resource
allocation problem to deal with the trade-off between offering security while
achieving a certain level of performance. In other words, we utilize a
mathematical optimization model to solve a security problem. In our proposed
solution, we use slice isolation as security constraints for the optimization
model to proactively mitigate DDoS attacks. Our experimental test results show
how DDoS could be mitigated and the impact on slice availability. We believe
this work will encourage further research in securing 5G network slicing.
