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.

assurance tasks. He is a frequent speaker at conferences and industry forums

including the IEEE, MIS, IEC, ISACA, VON, and others. Peter is also known

for his contributions to the security community for discovering software

vulnerabilities, the release of SiVuS (The First VoIP Vulnerability Scanner)

and the vopsecurity.org Forum. Peter holds a Masters Degree in Computer

Science from Columbia University where he is currently furthering his

graduate studies.

Ari Takanen is founder and CTO of Codenomicon. Since 1998, Ari has

focused on information security issues in next-generation networks and security

critical environments. He began at Oulu University Secure Programming Group

(OUSPG) as a contributing member to PROTOS research that studied information

security and reliability errors in WAP, SNMP, LDAP, and VoIP implementations.

Ari and his company, Codenomicon Ltd. provide and commercialize automated

tools using a systematic approach to test a multitude of interfaces on mission-critical

software, VoIP platforms, Internet-routing infrastructure, and 3G devices.

Codenomicon and the University of Oulu aim to ensure new technologies are

accepted by the general public, by providing means of measuring and ensuring

quality in networked software. Ari has been speaking at numerous security and

testing conferences on four continents and has been invited to speak at leading

universities and international corporations.
