Securing Voip Networks Threats, Vulnerabilities, Countermeasures

Securing VoIP Networks captures information about the risks, vulnerabilities, and security issues associated with VoIP networks and provides recommendations to protect against such threats. Examples and case studies throughout the book provide a uniquely alternative approach to the subject unlike the more theoretical alternative titles currently available. Based on actual field work covering the topics of the SIP and H.323 protocols, telecommunications, data security, vulnerability assessment and research, this book presents the topic of Voice over IP network security in a real-world manner that the reader can apply in their own daily work. This book discusses threats and vulnerabilities associated with VoIP and focuses on protection mechanisms for signaling and media protection including authentication, encryption and key exchange. In addition it offers methods and demonstrates techniques to test various vulnerabilities as part of a security evaluation methodology. Finally case studies for enterprise and carrier based networks are presented which describe the architecture, security requirements and security components that have been deployed in order to maintain an adequate security posture of a VoIP network.Thermos, Peter is the author of 'Securing Voip Networks Threats, Vulnerabilities, Countermeasures', published 2007 under ISBN 9780321437341 and ISBN 0321437349.
