Coluccio Respond to of 46821 Here's another interesting boast about security that appears on the surface to be counter-intuitive, but this one may hold more water than the Mozilla one, depending on where the code is mounted: ---- Security in VoIP Networks Stronger than TDM! by Haim Melamed Director, Channel Marketing AudioCodes The move from TDM networks to VoIP has created a new challenge for network operators end enterprises' security. Unlike in TDM networks, where the telephony network was almost completely isolated from the data network and the internet - most VoIP networks have many interface points with the data network, along with the dangers in the internet world. A poorly designed VoIP network can easily be exposed to security threats such as denial of service attacks, computer viruses and data theft. On the other hand, the technologies available today, in addition to a well designed network, can offer even better security than we had in the TDM world. Security is not a new concept for telephony managers. Telephony networks were always exposed to security threats like eavesdropping, impersonation, fraud and denial of service - similar to that of data networks. Moving away from a separated, dedicated TDM network to the well known, widely used IP network has exposed the telephony networks to a growing number of hackers, originating from the data world. While hacking in the TDM telephony world was limited to a small group who required physical access and dedicated equipment, the VoIP world is more accessible to a large community of internet hackers who are using readily available software tools.
