Better Protection of SS7 Networks with Machine Learning

Abstract

Deregulation and migration to IP have made SS7 vulnerable to serious attacks such as location tracking of subscribers, interception of calls and SMS, fraud, and denial of services. Unfortunately, current protection measures such as firewalls, filters, and blacklists are not able to provide adequate protection of SS7. In this paper, a method for detection of SS7 attacks using machine learning is proposed. The paper clarifies the vulnerabilities of SS7 networks and explains how machine learning techniques can help improve SS7 security. A proof- of- concept SS7 protection system using machine learning is also described thoroughly.
