Chepstow, UK. 24th October, 2005. Newport Networks is announcing the availability of the industry's most comprehensive security suite for Session Border Control in IP-based service infrastructures. Newport's Revenue, Core & Nodal Protection (RCNP) security package addresses vulnerabilities in SIP (Session Initiation Protocol), the standard for IP-based multimedia services. RCNP prevents service fraud and protects network operators against attacks on the 1460 session controller and other network elements such as Softswitches.
"Security continues to be of paramount concern to Tier 1 network operators looking to future-proof their investments and infrastructures," says Mike Wilkinson, Vice President of Marketing at Newport Networks. "Delivering a true carrier-class Session Border Control solution requires a multi-faceted approach that addresses not only device security, but also fraud and malicious attempts to bring down the network."
Newport's three-pronged RCNP suite addresses:
Revenue Protection
Newport's 1460 Session Border Controller prevents service fraud by policing calls to ensure that subscribers cannot use more bandwidth than they have negotiated. Policing occurs in both media and Real Time Control Protocol (RTCP) streams to prevent rogue users sending information through the RTCP Stream undetected while paying only for use of the media stream. Signalling is policed on a per-user basis to ensure that data is not exchanged between users prior to call setup.
Core Network Protection
Newport Networks' "Core" network protection adds critical security policies that prevent Denial of Service (DOS) attacks from impacting core network equipment such as Softswitches. The 1460 provides complete topology hiding for the network, ensuring that the overall topology is not exposed to attacks while also securing privacy of the subscriber base.
In keeping with a forward-looking, IMS-ready strategy, traffic directed at the 1460 can be separated into signalling and media. Media traffic is checked to ensure that it has come from a valid registered user and bandwidth policed so as not to exceed negotiated rates. Media coming from invalid sources is dropped at wire speed. Signalling traffic is filtered according to user registration. For those registered, signalling is rate-limited on a per session basis to ensure that neither equipment malfunctions nor fraud attempts generate excessive messages. Traffic from non-registered users is similarly rate-limited to prevent its arrival rate from impacting Softswitches in core networks.
Node Protection
Newport Networks' Node Protection shields the 1460 from malicious Denial of Service attacks. The 1460's unique carrier-class design incorporates physically separate management and data planes so that DOS attacks cannot disrupt management data. Management interfaces are encrypted and kept physically separate from traffic interfaces, with access lists and encrypted passwords used to deny unauthorized access.
The RCNP security suite is included as part of a broad range of capabilities in release 2.0 of Newport Networks' 1460 Session Border Controller. For more information on Newport's RCNP security suite please visit www.newport-networks.com/security
