New tools help the enterprise secure VoIP

Researchers at the Black Hat security conference in Las Vegas released 13 new tools that aim to help the enterprise probe for vulnerabilities in their VoIP deployments. The researchers engineered each of the tools to specifically test SIP-based VoIP systems, which are becoming increasingly popular, but are by no means widely deployed yet. For instance, most if not all products from Cisco, Avaya and Nortel use proprietary protocols at this time. Attendees at Black Hat said the release of the tools will not effect VoIP users today, but they will become integral to the industry once the various solution providers begin launching SIP-based systems that will work with each others' VoIP exchanges.
