Although 5G (fifth generation) networks are still in the realm of ideas, their architecture can be considered as reaching a forming phase. There are several reports and white papers which attempt to precise 5G architectural requirements presenting them from different points of view, including techno-socio-economic impacts and technological constraints. Most of them deal with network slicing aspects as a central point, often strengthening slices with slice isolation. The idea of isolation in the network is not new. However, currently considered technologies give new capabilities that can bring added value in this field. The goal of this paper is to present and examine the isolation capabilities and selected approaches to its realization in network slicing context. As the 5G architecture is still evolving, the specification of isolated slices operation and management brings new requirements that need to be addressed, especially in a context of end-to-end (E2E) security. Thus, an outline of recent trends in slice isolation and a set of challenges are presented. The challenges, if properly addressed, could be a step from the concept of 5G networks to proof-of-concept solutions which provide E2E user’s security based on slices isolation. Among other things, the key features are proper slice design and establishment, security at interfaces, suitable access protocols, correct virtual resources sharing, and an adaptable management and orchestration architecture (MANO). In conclusion of the paper, short outlines of two of the main secure isolation challenges are given: a proper definition of isolation parameters and designing suitable MANO system.
