UMTS Security

UMTS Security

Having completed this course the participant will be able to understand how security is implemented, deployed and managed in UMTS network, understand security concepts, understand the benefits of new security techniques applied and how they are implemented.

Objectives
The goal of this course is to give the participant a strong and intuitive understanding of what security in the wireless systems is and how the security functions are implemented in UMTS radio and core network. The course focuses both on the air interface and the core network.
