2.3.7. GPRS tunneling protocol (GTP) Security
GTP signalling has been a part of mobile network signalling since the mid-1990s. Since these messages travel on the GPRS Exchange (GRX) or IP Exchange (IPX) between networks, they can be exploited at the interfaces exposed to those networks. And, just like SS7 and Diameter, GTP messages routinely carry a wealth of user data that can be exploited and manipulated. This module will identify the risks and countermeasures.
Your Instructor
Steve is currently Head of Training & Development at Cellusys. He has over 40 years of experience in the telecom industry and has worked in technical support at Ameritech and as a Member of Technical Staff at Bell Communications Research (Bellcore) where he was first introduced to SS7. Later, he worked as a Training Manager at Bellcore (later Telcordia Technologies) developing and teaching classes in SS7 and Intelligent Networking.
What will you learn?
In this module, we will start by giving a brief overview of the various SS7 layers and their security issues. Though potential harm exists in each layer, it is the SCCP layer that contains some of the more “useful” information about origination and destination addressing. Signalling Transport (Sigtran) greatly increased the capacity of the traditional low-speed links. Being “IP-based”, it has introduced some unique signalling security challenges. This module will also explore some of those challenges.
