Vunneling™: DataTheft with VoIP
An enterprise VoIP network presents a significant opportunity for data theft. Voice networks are designed to handle lots of traffic very quickly. Unfortunately, the VoIP network that was intentionally designed as a "super-highway" to provide great voice quality can be used to very quickly move data outside of the company's physical and virtual walls. Existing security appliances are unable to stop this abuse because they slow down and interrupt traffic through the use of deep packet inspection. Since slowing down and interrupting voice would dramatically garble and distort voice communication, deep packet inspection can not be used.
Encryption is also widely used to provide privacy for VoIP calls. In fact, encryption is the only solution that delivers private and secure communications. But once the media is encrypted, the content may or may not be voice. Who can tell? Inspection of the media stream is impossible because it is not visible as the result of encryption. So not only can your data can flow out of your enterprise, it can flow out without detection!
Salare Security develops and markets unique VoIP security solutions that stop data leakage through VoIP channels. Unlike other security appliances, Salare’s products do not use deep packet inspection and thus do not degrade the Quality of Service (QOS) of voice. Salare Security's products even prevent point-to-point encrypted media streams from carrying data.
If you must comply with HIPAA, SOX or GLBA and have VoIP traffic (sanctioned or unsanctioned) you need to act now. Both insiders and outsiders can steal data from your network and do so without detection.
