BorderWare Develops SIP Firewall for VoIP Security
Of all the security concerns that affect an enterprise, the most disturbing ones are the ones committed internally by its own employees. Unprotected VoIP networks can be a nightmare for those using it as new hacking techniques like VoIP eavesdropping make them vulnerable to various kinds of cyber crime.
Encryption of voice packets has been adopted by several companies in order to protect their VoIP networks, but such encryption needs to be centralized so as to prevent the violation of certain legal requirements and also to provide for an easy functioning of the network within the company. SIP firewalls are being developed to address the specific security requirements of VoIP and other SIP related communications.
BorderWare, an Internet security provider, has introduced a new SIP firewall that does deep packet inspections to prevent fraud and unauthorized access to VoIP networks. Though there are security products available to filter IM traffic and VoIP traffic, BorderWare's product is the only one providing filtering of SIP traffics at the application layer. BoderWare's appliances are included in the general purpose firewall, where at the time of its deployment certain ports are opened up enabling the VoIP firewall to handle the VoIP traffic.
As most companies are adopting the SIP protocol for all real-time communications, a SIP specific firewall will eventually come in demand.tmcnet.com reports:
