This book gives a detailed overview of SIP specific security
issues and how to solve them

While the standards and products for VoIP and SIP services have
reached market maturity, security and regulatory aspects of such
services are still being discussed. SIP itself specifies only a
basic set of security mechanisms that cover a subset of possible
security issues. In this book, the authors survey important aspects
of securing SIP-based services. This encompasses a description of
the problems themselves and the standards-based solutions for such
problems. Where a standards-based solution has not been defined,
the alternatives are discussed and the benefits and constraints of
the different solutions are highlighted.

Key Features:

* Will help the readers to understand the actual problems of
using and developing VoIP services, and to distinguish between real
problems and the general hype of VoIP security

* Discusses key aspects of SIP security including
authentication, integrity, confidentiality, non-repudiation and
signalling

* Assesses the real security issues facing users of SIP, and
details the latest theoretical and practical solutions to SIP
Security issues

* Covers secure SIP access, inter-provider secure communication,
media security, security of the IMS infrastructures as well as VoIP
services vulnerabilities and countermeasures against
Denial-of-Service attacks and VoIP spam

This book will be of interest to IT staff involved in deploying
and developing VoIP, service users of SIP, network engineers,
designers and managers. Advanced undergraduate and graduate
students studying data/voice/multimedia communications as well as
researchers in academia and industry will also find this book
valuable.
