Network slicing is a key capability provided to Fifth Generation (5G) mobile network operators. The industry has defined many predefined network slice types that depend on various key performance indicators (KPIs) such as bandwidth, throughput, and latency. However, one missing component, in terms of KPIs for defining network slices, is security, as there is currently no mechanism to translate network security or segmentation of traffic into a 5G core network or Radio Access Network (RAN). Presented herein are techniques to enable micro segmentation of a 5G network by using security as a KPI. The techniques provided herein can be achieved by leveraging existing security capabilities and algorithms to determine a reputation of endpoints and embedding the reputation within a slice differentiator.
