Preface xxxvii
● Technology Architects and Standardization Bodies: 5G is going to cross the traditional
mobility borders and is going to have an equal impact on enterprises and organizations who are planning to transform into digital businesses. It would be critical for
architects to start aligning their technology and security architectures to the future
needs of 5G standards. This book offers resources to design and build a security
architecture and maintain it.
● IoT and Industrial Internet experts: Internet of things is going to change the way
industrial networks are built, and 5G is going to provide the underlying platform for
IoT networks. Security has remained the top priority for industries due to criticality
and sensitivity of the data and information flows in their networks. Advance knowledge of 5G security principles, components and domains is going to help industries
lay a foundation of IoT security. This book will provide the guidelines and best practices for 5G‐based IoT security.
Book Organization
The book is divided into four parts covering various aspects of 5G security ecosystem:
Security Overview, Network Security, Device and User Security, and Cloud and Virtual
Network Security.
The first part provides an introduction to 5G and history of preceding systems, an
overview of 5G security architecture, and general aspects of telecommunication security. The first chapter describes the evolution of cellular systems. For each generation,
from 1G to current 4G, its architecture and security mechanisms are presented. The
second chapter focuses on 5G mobile networks from the viewpoint of requirements
and enabling technologies. The main 5G system components (radio, core, end‐to‐
end), standardization and research activities are surveyed. The third chapter on mobile
network security landscape describes attacks possible in the existing and previous
generation mobile communication systems. Severity and estimated frequency of
threats are analyzed, concluded by the evolved 5G security model. The fourth chapter
considers secure 5G software‐defined network architecture. The fifth chapter concludes Part I with an overview of cyber‐security preparedness framework.
Part II takes an in‐depth look at security of core and radio interfaces. Chapter 6 introduces radio signal watermarking as a way to achieve security at the physical layer. The
application of this concept to 5G architecture is proposed. Chapter 7 treats interoperability between 5G and Wireless LANs (WLANs) from the security viewpoint. This
chapter compares possible attacks in 5G and WLANs and proposes a common interoperability architecture. Chapter 8 focuses on safety of physical infrastructure in 5G.
Structural resilience of mast poles to natural disasters and deliberate attacks by humans
are described. Chapter 9 is dedicated to Customer Edge Switching (CES). It is a security
framework for 5G, which extends functionality of Network Address Translation (NAT)
at the edges. Finally, Chapter 10 introduces a Software Defined Security Monitoring for
5G Networks. The use of novel Software Defined Networking (SDN) and Network
Function Virtualization (NFV) concepts in 5G monitoring systems can address the classical weaknesses in legacy monitoring systems.
Part III considers security outside of the operator’s part of the 5G network; namely, on
user equipment such as smartphones and embedded modems and the users themselves.
