Engineer
The complete 5G security engineering track. From LTE/EPC foundations and 5G identity through the NR air interface to advanced SBA, O-RAN, and network slicing security - the definitive career path for 5G security engineers.
// OVERVIEW [PATH CONTEXT]
Path Context & Goal
The 5G Security Engineer track builds mastery across the complete 5G stack. Start with fundamentals - SUCI identity protection, 5G-AKA authentication, and the key hierarchy - then master the NR air interface with scalable numerologies, RACH procedures, beam management, and mobility protocols. Complete the journey with the advanced security module covering SBA network functions, SEPP roaming, Open RAN xApp threats, and network slicing isolation. Graduate with end-to-end competency across every layer of 5G security.
// THE CURRICULUM [LEARNING OBJECTIVES]
5G Identity & Auth
Decode SUCI/SUPI privacy protection, 5G-AKA flows, and the TS 33.501 key hierarchy.
NR Air Interface
Master numerology, slot formats, RACH procedures, reference signals, and BWP configuration.
SBA Architecture
Audit NF service mesh security, HTTP/2 trust boundaries, and SBA API exposure points.
SEPP & Roaming
Analyze PRINS inter-PLMN signaling and the N32 interface security model.
O-RAN Security
Evaluate xApp isolation, E2 interface attacks, and the Near-RT RIC threat model.
Slicing & Hardening
Implement NESAS-aligned hardening checks and network slice isolation controls.
The 5G Security Engineer path builds end-to-end mastery of the 5G stack: SUCI/SUPI identity, 5G-AKA, the NR air interface, SBA network functions, SEPP roaming, O-RAN threats, and network-slice isolation.
- Covers the full 5G stack from air interface to core.
- Includes SBA/SEPP roaming and O-RAN xApp threat models.
- Graduates earn the 5G Security Engineer designation.
