Securing Telecom Networks: A Deep Dive into SS7 and SIGTRAN
The legacy Communication System No. 7 (SS7) and its modern successor, SIGTRAN, present considerable risks Telecom to network security. Historically designed for reliability and connectivity rather than native defense, these protocols are open to a variety of abusive attacks, including eavesdropping on calls, phony SMS messaging, and even disrupting vital services. Modern SIGTRAN deployments, while offering benefits through IP transport, still utilize the fundamental SS7 architecture and therefore inherit some of its present vulnerabilities. Understanding the complexities of SS7 and SIGTRAN, along with deploying effective safeguards, is totally necessary for preserving the secrecy and uptime of today's sophisticated network infrastructure.
LTE Signaling Systems: Difficulties and Advanced Solutions
