Author Biography

Peter Thermos is CTO of Palindrome Technologies, which provides information

security consulting services to government and commercial organizations.

Peter started his career at Bellcore (now Telcordia) as a member of the technical

staff and later as a principal technical expert on key information security and

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.

The ability to communicate across continents in real-time has also helped our society in several dimensions including entertainment, trade, finance, and defense. But this new capability did not come without an investment. Building an international telephony infrastructure has required the cooperation of both commercial and government organizations to evolve into what it is today. It has also led to the formation of international standard bodies that both direct and support the industry towards an interoperable communication networks.IP networks are the next step from the traditional telecommunications. For a while, IP family of protocols was only used in the Internet, and the main applications were file transfers and e-mail. With the World Wide Web, the Internet changed into a global and always open information distribution channel. And finally with the advent of VoIP, the Internet is becoming a real-time communication media that integrates with all the earlier multimedia capabilities.Traditional telecommunication networks are critical to the survival of our society. The PSTN is a closed network and its operational intricacies are known to a few select individuals who have devoted much of their lives to building it. Although operations in PSTN are not entirely a secret, they were and still remain proprietary for several reasons such as competitive advantage and national defense. The PSTN was and remains a closed infrastructure that concentrated its intelligence in its core network elements and left the edge devices very simplistic. The equipment and resources to operate a TDM network require a substantial financial investment. This lack of direct access to core network elements from subscribers and the high price of connectivity alleviated the risk for attacks. Ergo, subscribers demonstrate greater trust for communications through the PSTN compared to the Internet. This is a misconceived trust once you start analyzing the PSTN components and protocols and realize the lack of protection mechanisms.In the earlier days of the Internet,
