VoIP Security

"Voice Over Internet Protocol Security is both unique and timely. Ransome and Rittinghouse expertly describe the technical fundamentals, salient business drivers, and converged network infrastructure security risks and challenges IT and security professionals encounter when implementing enterprise-level VoIP systems." William M. Hancock, Ph.D., CISSP, CISM, CSO, Savvis Communications. "This book should be required reading for anyone contemplating a VoIP implementation for three reasons: first, it deals with telecom technology and standards from Alexander Graham Bell onward. This puts VoIP in its proper context as an integral, evolved part of a global system that is potentially vulnerable. Second, it provides a detailed tutorial on all of the major aspects of VoIP implementation from a pragmatic point of view. Finally, it addresses the very real security issues that could put the global telephone system at risk if not dealt with professionally. I would heartily recommend your entire project team buy this book and read it carefully!" John Milner, MIS Director, Cambridge University Voice Over Internet Protocol Security has been designed to help the reader fully understand, prepare for and mediate current security and QoS risks in todays complex and ever changing converged network environment and it will help you secure your VoIP network whether you are at the planning, implementation, or post-implementation phase of your VoIP infrastructure. * This book will teach you how to plan for and implement VoIP security solutions in converged network infrastructures. Whether you have picked up this book out of curiosity or professional interest . . . it is not too late to read this book and gain a deep understanding of what needs to be done in a VoIP implementation. * In the rush to be first to market or to implement the latest and greatest technology, many current implementations of VoIP infrastructures, both large and small, have been implemented with minimal thought to QoS and almost no thought to security and interoperability.
