Introduction
The emergence of Voice-Over-IP (VoIP)
technology is creating a major discontinuity
in telecommunications. The promise of
reduced hardware and operations costs
coupled with new value-added services
makes VoIP, as well as Internet Protocol
(IP) TV, videoconferencing, IP Multimedia
Subsystem (IMS) and presence services, a
compelling solution for enterprises and
service providers. Current voice services
which are delivered using Public Switched
Telephone Networks (PSTN) provide high
voice quality, very high reliability (99.999 per
cent), carry critical services such as E911,
enable federal agencies with ability for lawful
intercept, all while offering an extremely high
level of security. For VoIP networks to
become a reality, both enterprises and
service providers must be able to ensure
that voice networks are able to deliver the
identical quality, reliability, flexibility and
security to that of PSTN.
With enterprises, carriers and cable
companies publicly committing to VoIP
deployments, security has quickly emerged
as one of the biggest barriers to the
successful deployment of VoIP. To securely
implement VoIP networks a proactive
approach and an understanding of the
differences between VoIP and traditional
data networks is required. This document
examines these differences, new types of
attacks, and provides a comprehensive
security architecture for VoIP networks in
the context of practical VoIP security
problems.
