Ensuring SS7 Network Security

GL Communications Inc. a global leader in telecom test and measurement solutions, providing information about vulnerabilities in SS7 (SIGTRAN) networks and insights into GL’s MAPS SS7 solution capable of generating such real-time SS7 attacks by simulating various SS7 messages and manipulation of SCCP, MAP, CAP parameters. In addition, GL’s Network Monitoring and Surveillance Solution can be deployed at probe level to monitor the SS7 traffic.

Speaking to the press, Mr. Vijay Kulkarni CEO of GL Communications Inc. said “Mobile communication infrastructures have evolved from traditional circuit-based networks into broadband and IP-based networks. In this process SIGTRAN was proposed for carrying SS7 PSTN signaling over IP. The vulnerabilities in SS7 signaling protocol was inherited to SIGTRAN thus susceptible for intruders’ attacks. An intruder can send, intercept and alter SS7 messages by executing various attacks against mobile networks and their subscribers. Although large scale attacks are not common, still they may significantly impact individual subscribers with financial loss, confidential data leaks, and/or disruption of communication services (voice and sms).”

“GL’s MAPS Protocol Simulator and NetSurveyorweb monitoring system provides a complete solution required to ensure SS7 network security”, said Mr. Vijay Kulkarni CEO of GL Communications. “GL’s MAPS (SS7 MAP/CAP) test platform supports inbuilt pre-processing tools that allow the users to customize the SS7 protocol specific parameters and create custom scripts to perform real-time fraud scenarios addressing some critical attacks. Examples of such attacks include tracking a subscriber’s location, data theft, eavesdropping, text interception, unstructured supplementary service data (USSD) forgery requests, and voice call redirection.”

“Besides NetSurveyorWeb Lite can be deployed along with Protocol analyzer across the network at probe level for monitoring the SS7 traffic for detecting and reporting un-lawful activities, identify fraudulent calls (call records), data retention, targeted surveillance, and study usage patterns with customized tabular and graphical report generation.”
