5G Network Application Security: Testing the New Attack Surface cho Doanh nghiệp Việt Nam

5G networks introduce new application architectures that expand the attack surface: network slicing creates isolated virtual networks that must maintain strict tenant separation, multi-access edge computing (MEC) pushes application processing to the network edge, and massive IoT connectivity enables millions of connected devices. Application security testing for 5G environments focuses on: network slice isolation verification, MEC application security, API gateway security for 5G service exposure, authentication in network function virtualisation, and the IT application layer of telecom operators deploying 5G services.
