Transport Security
Transport Security
Securing global optical backbones, submarine cables, and IPX/GRX transit networks. Master the physical and logical security of the infrastructure that connects mobile cores across continents.
// OVERVIEW [PATH CONTEXT]
Path Context & Goal
Mobile networks are only as secure as the physical and logical infrastructure connecting them. This path covers the full transmission stack from passive optical access networks (GPON, XGS-PON), terrestrial backhaul, MPLS core transport, submarine cable systems, and IPX/GRX international roaming transit. You will learn to identify physical tap points, audit MPLS label manipulation, and assess the security posture of carrier interconnect infrastructure.
// THE CURRICULUM [LEARNING OBJECTIVES]
Optical Access
Understand GPON and XGS-PON architecture and ONT provisioning security.
Submarine Cables
Identify physical tap points and cable landing station threat models.
MPLS Security
Audit core transport MPLS label handling and traffic isolation.
IPX/GRX
Assess roaming transit security using PRINS/N32 and GSMA FS.11.
