The introduction of Voice Over IP (VoIP) marks a new chapter in the history of both the Internet and Telecommunications. For the first time, an established communications service is extending to an IP network. This is in contrast to other IP applications such as web and email that were developed to run on IP networks and have grown up with the Internet. VoIP introduces an established service, that has its own well-defined set of service expectations, to the much less ordered world of IP networking.
The need for security for IP applications is well understood, yet the lessons learned from 15 or more years are not consistently applied to VoIP.
VoIP and related messaging applications such as Video Conferencing, Presence applications and Instant Messaging deliver specialist services over an IP network. Securitng these applications requires a combination of standard security technologies to detect and address the IP level threats and application specific measures to detect and address those threats not handled by standard security technologies.
Many VoIP networks rely solely on security measues designed for web and email which simply do not address the full set of threats facing VoIP networks.
The bottom line is that relying solely on general purpose Firewalls and other standard security technologies can leave your VoIP network open to a range of threats that these standard technologies are simply not designed to address.
