Juniper Develops Tool for MSOs to Secure VoIP, SIP Services

(NewTelephony.com) April 10, 2006 -- Juniper Networks Inc. today at NCTA unveiled a new product, the Cable Dynamic Threat Mitigation tool, which helps cable MSOs protect VoIP and SIP services against network security attacks.

The Cable Dynamic Threat Mitigation solution works with any PacketCable Multimedia-compliant cable modem termination system. It integrates Juniper's routing platforms, intrusion detection and prevention devices and SDX Service Deployment System so MSOs can identify and isolate security threats, then notify operations staff and infected customers.

The intrusion detection and prevention device monitors for network attacks on a per-user, per-application, or on-demand basis, and detects offending traffic or a DDoS attack. It then notifies the SDX-300, which sends the appropriate policy to any Juniper Networks routing platform and/or third-party PacketCable Multimedia-qualified cable dynamic threat mitigation or metro routing platform. According to the nature of the threat, MSOs can choose to rate limit or filter traffic, drop the call, or redirect the user to a Web portal, and automatically re-establish service once the threat is eliminated.

Juniper’s Cable Dynamic Threat Mitigation tool also can provide security for SIP-based services, such as online gaming, video conferencing, instant messaging, and push-to-talk.

"Cable operators have been quite successful at expanding into voice services, but like any IP-based service, VoIP can be vulnerable to security threats," said Andrew J. Audet vice president of the cable products business for Juniper Networks. "With this solution, Juniper provides a whole-network approach to monitoring and securing advanced IP-based services against a range of threats.”
