  Malicious co-residency in virtualized networks poses a real threat. The
next-generation mobile networks heavily rely on virtualized infrastructure, and
network slicing has emerged as a key enabler to support different virtualized
services and applications in the 5G network. However, allocating network slices
efficiently while providing a minimum guaranteed level of service as well as
providing defense against the threat of malicious co-residency in a mobile core
is challenging. To address this question, in our previous work, we proposed an
optimization model to allocate slices. In this work, we analyze the defense
against the malicious co-residency using our optimization-based allocation.
