Re: [Stackevo-discuss] [5gangip] [gaia] 5G: It's the Network, Stupid

That is only true if stat mux transport is not used for backhaul/midhaul. If OTN or DWDM is used for isolation of slices then of course no interference is possible however with a packet mix there is the possibility of DOS or at the least Denial of QOS (DOQ?) but in general you are right that properly sliced there should be minimal security impacts between slices.

E2E security in 5G can be addressed through network slicing, another concept which seems to be included in many 5G proposals. If each application has its own slice, it can screw up but wont be able to affect other applications. Within each slice, E2E security can be enforced in an application specific manner. Even better would be if we can make each flow be its own slice. This may seem to be overly heavyweight, but is along the lines of what Bromium  is trying to do for desktops, isolating processes and data from each other using
"microvisors": http://www.bromium.com/why-bromium/how-we-do-it.html We just need to do it for networks :)
