3 GSMA Categorization

For protection against attacks, a comprehensive approach to information security is taken. The security of a signaling network is analyzed, which allows detection of current vulnerabilities in the network and helps in assessing information security risks. The possible attacks are described in the Appendix sections of this document.

GSMA recommendations specify the use of a monitoring system, which can perform analysis in real time. This enables detecting phishing or anomalies in a network at an early stage.

This section describes the different recommended details of SS7 security aspects for vSTP, in order to counter the potential SS7 attacks.
