Securing VoIP Networks [EPUB ebook] 

In Securing Vo IP Networks, two leading experts systematically review the security risks and vulnerabilities associated with Vo IP networks and offer proven, detailed recommendations for securing them. Drawing on case studies from their own fieldwork, the authors address Vo IP security from the perspective of real-world network implementers, managers, and security specialists. The authors identify key threats to Vo IP networks, including eavesdropping, unauthorized access, denial of service, masquerading, and fraud; and review vulnerabilities in protocol design, network architecture, software, and system configuration that place networks at risk. They discuss the advantages and tradeoffs associated with protection mechanisms built into SIP, SRTP, and other Vo IP protocols; and review key management solutions such as MIKEY and ZRTP. Next, they present a complete security framework for enterprise Vo IP networks, and provide detailed architectural guidance for both service providers and enterprise users. 1 Introduction 2 Vo IP Architectures and Protocols 3 Threats and Attacks 4 Vo IP Vulnerabilites 5 Signaling Protection Mechanisms 6 Media Protection Mechanisms 7 Key Management Mechanisms 8 Vo IP and Network Security Controls 9 A Security Framework for Enterprise Vo IP Networks 10 Provider Architectures and Security 11 Enterprise Architectures and Security
