Constructing on current networks dangers exposes 5G to outdated dangers

At the moment’s 5G networks principally depend on the infrastructure of previous-generation 4G LTE networks. The non-standalone structure has proved a fast means to offer subscribers with 5G entry, nonetheless, this additionally exposes each the next-generation community and 5G subscribers to the identical threats as older networks.

A brand new white paper from Positive Technologies particulars how cell community operators (MNOs) who’ve already begun upgrading to 5G networks can migrate from earlier technology networks with out exposing themselves and their subscribers to current and new dangers.

“For years to come back, most 5G networks will proceed to depend on 4G networks, which implies 5G-only safety efforts are pointless and harmful,” says Pavel Novikov, head of the telecom safety analysis group at Optimistic Applied sciences. “Subsequently, true 5G safety should transcend the options constructed into standalone structure. Price efficiencies may be gained by constructing a hybrid community that helps each LTE and 5G which is able to allow a future-proofed subsequent technology community in the long term. This permits cell operators so as to add new 5G-capable subscribers, whereas persevering with to help older ones to supply a full-service community. To defend 5G networks, it is essential to pay particular consideration to signalling networks, utilising current defences, and including extra layers particular to 5G. The community have to be fastidiously checked for configuration errors, requiring common evaluation of the state of infrastructure safety.”

Earlier Positive Technologies research has proven that an attacker can exploit Diameter vulnerabilities in 4G to trigger denial of service assaults, observe subscriber location, receive subscriber profile info, and commit fraud. Within the newest report, Optimistic Applied sciences consultants argue that with 5G non-standalone structure, previous-generation protocols have to be secured, since networks are so intertwined merely defending 5G just isn’t sufficient.
