GSMK and sternraute introduce Oversight product line02.03.2015

At MWC 2015 in Barcelona, 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. 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.

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