Sonus and Cellusys Collaborate to Provide Mobile Network Operators with SS7 Security Solution

WESTFORD, MA: Sonus Networks, a secure and intelligent cloud provider, collaborates with Cellusys to provide wireless network providers with several levels of Signalling System 7 (SS7) security solution.

By combining Sonus' Signaling Transfer Points (STP) and Cellusys' Signaling Firewall, operators can provide network protection for subscribers from illegal tracking, call intercept, fraud and Denial of Service (DoS) attacks. For SS7 messages where there are concerns regarding legitimacy, the STP forwards the message to Cellusys' Signaling Firewall to provide context and stateful message assessment to ensure private information is not exposed.

Signalling System 7

SS7 is a telecommunications standard that provides the signalling for network operators to set up and tear down calls, route Short Message Service (SMS) messages, support inter-network connectivity and transparent roaming, and provide per-session information. As SS7 networks have expanded outside of trusted operator environments, security exposures have revealed network vulnerabilities.

“There’s a lot of discussion around the migration to Diameter and LTE Networks. Yet, SS7 protocol-based networks serve the vast majority of mobile subscribers and indications are that SS7 will be around for quite some years,” says Dawood Ghalaieny, CEO, Cellusys. “With increasing interest on SS7 security flaws from global mainstream media – and from network operators and subscribers – it’s critical we address these vulnerabilities immediately. We are optimistic about working with Sonus to provide network operators with a complete security solution to counter these malicious attacks.”
