Product Description
In Securing VoIP Networks, two leadingexperts systematically review the security risks and vulnerabilitiesassociated with VoIP networks and offer proven, detailedrecommendations for securing them. Drawing on case studies from theirown fieldwork, the authors address VoIP security from the perspectiveof real-world network implementers, managers, and security specialists.The authors identify key threats to VoIP networks, includingeavesdropping, unauthorized access, denial of service, masquerading,and fraud; and review vulnerabilities in protocol design, networkarchitecture, software, and system configuration that place networks atrisk. They discuss the advantages and tradeoffs associated withprotection mechanisms built into SIP, SRTP, and other VoIP protocols;and review key management solutions such as MIKEY and ZRTP. Next, theypresent a complete security framework for enterprise VoIP networks, andprovide detailed architectural guidance for both service providers andenterprise users.
