Mobile security specialists GSMK and sternraute close cooperation to protect network operators against SS7 attacks

Combined expertise used in new network security products that secure operators’ core networks

Barcelona, March 2 – Mobile security specialists GSMK and sternraute today announced a close cooperation in order to protect the core networks of their operator customers against recent security breaches that compromise the security and integrity of inter-operator signaling.

The new GSMK Oversight product line addresses recently publicized security vulnerabilities in the SS7 communications protocol that forms the foundation of most inter-operator traffic exchange. The security vulnerabilities, which were disclosed in late December, allow mobile subscriber tracking, remote eavesdropping on calls and messages, and billing fraud. Responding to this exorbitant threat, the two companies combined their expertise in building secure systems and an in-depth understanding of SS7 protocol particularities in order to formulate a robust response to these profound threats impacting the very core of operator networks. Oversight Detect is a comprehensive intrusion detection system that is capable of identifying protocol violations and/or misuse by fraudsters and other unauthorized foreign or domestic entities alike. Using high-performance real time analysis as well as a state of the art monitoring rule set with automatic updates, Oversight Detect permits network operators to identify and report threats. A companion product, Oversight Protect is an SS7 firewall that can automatically block illegal traffic at each SS7 Signal Transfer Point, thus preventing such traffic from penetrating the core network.

“Operators can now automatically detect protocol violations and misuse that would otherwise lead to billing fraud, data theft, and denial of service attacks”, commented Tobias Engel, sternraute’s Managing Director. “Far-reaching vulnerabilities like the recently disclosed security breaches affecting operator core networks require decisive countermeasures”, added Dr. Bjoern Rupp, GSMK’s Chief Executive Officer. “Thanks to the pooled expertise of GSMK and sternraute, network operators and regulators alike can defend key elements of their respective national telecommunications infrastructure against a wide range of attackers ranging from fraudsters to foreign intelligence agencies.”

GSMK and sternraute are showcasing their new Oversight network security products at Mobile World Congress 2015 in Barcelona in Hall 6, Stand J07.
