The commercial and regulatory drive to roll out 4G/5G networks is generally welcomed by all stakeholders. Mobile Network Operators (MNOs) can increase network capacity by refarming valuable spectrum from “legacy” 2G and 3G network services to facilitate the provision of more enhanced services to their customers while regulators and authorities will be pleased to see faster speeds, better connectivity, and more enhanced and flexible communication services available to the public.
This blogpost is intended to help minimize the impact of a cyber attack. First, the process of a typical attack is shown. We then explain what the separation of networks means in theory. Finally, concrete practical measures are shown on how networks can be separated sensibly.
