5G Security Flashcards

Q
At a high level what are some of the security enhancements in 5G?
A
- Improved subscriber privacy - SUPI now encrypted; use of SUCI,
- Stronger over-the-air encryption
- Introduction of SEPP for roaming protection (SS7 and Diameter deprecated due to vulnerabilities)
- SBA in core network enables ZT implementations
- Improved DDoS resilience by detecting attacks at the edge (not sure how this works - is it because of the UPF being deployed at the edge? Open interfaces and security analytics in the ORAN interfaces enables quicker detection)
- Network slicing - isolation of traffic; customized security policy
