See Full StoryThey have their networks locked tight, their data hidden behind firewalls and their e-mail scanned by virus protection software. But too many IT managers and security officers overlook a crucial security risk: the telephone system. As voice over IP (VoIP) setups become more common, the risk of compromise of phone services is on the rise. "When it comes to telephone systems, we're so comfortable that when a security breach occurs, it's like being punched by someone you love -- you're just not expecting it," Jim Puchbauer, director of marketing at AltiGen Communications, told the E-Commerce Times.
Re: The New Security Risk of VoIP

There is a new emerging technology that resolves security risks for these new IP Communications Systems, called a Session Controller. Basically, it acts as a firewall, NAT and Intrusion Prevention System for VoIP.
A new technology is required because the new VoIP systems are not protected by existing data firewalls. These firewalls are typically not prepared to handle real time communications with multiple control and media flows. Opening static ports in your data firewall can compromise your information security. Some firewalls purport to have special software that can provide security, but at a performance cost to the firewall.
Session controllers work in concert with data firewalls to ensure network integrity for both voice and data.
