I will come to the issue of the network’s core and edge, which will answer some of the questions that Members want to ask.
Ian Levy, the technical director of the National Cyber Security Centre, set out in a recent blog post that the notion that there is no distinction between the core and the edge cannot be true. He says that, with 5G networks,
“you need lots of smaller basestations as well as big ones, and the small ones will be on lampposts, bus shelters and other places that aren’t secure from physical interference by bad guys. So, if your network design means that you need to run really sensitive functions processing really sensitive data (i.e. core functions) on an edge access device on top of a bus stop, your choice of vendor is the least of your worries and you probably shouldn’t be designing critical national infrastructure. The international standards that define what a 5G network actually is allow you to do all sorts of things, and some of those things could lead to security or operational risks that can’t be mitigated. That doesn’t mean you have to do them.”
We in this country will not do such things.
