Juniper Networks Inc has announced a system that protects service providers and enterprises from attacks against VoIP systems such as worms and DOS (denial of service) threats.


Juniper Networks Dynamic Threat Mitigation system identifies attacks on specific users or applications and blocks the VoIP attack by using policy enforcement and control.

With IP telephony, VoIP signaling and the voice medium itself needs to be protected so network services aren’t stolen and critical information is not stolen or overheard, the network isn’t brought down or unauthorized users can eavesdrop on conversations

Juniper’s system includes an IDP traffic-processing box that identifies anomalies in traffic, such as in SIP flows, and worms and viruses. The IDP detects anomalies and notifies a SDX software application, which in turn sends policies to network devices based on user information. Predefined policy instructs SDX on what to do and sends that policy to the device.

A service provider, using SDX and IDP, could offer the system as a managed service, or an enterprise could deploy it, generally with the help of a systems integrator.

The system requires the Juniper M-series or E-series router, IDP and SDX products, and pricing will depend on the level of customization and size of the deployment.
