  15. 15. 15 Big Data Analytics for Fraud Management Using Deep Packet Inspection (DPI) and Pattern Matching is highly effective for:  Identifying malicious calls & applications in real time  Detecting abnormal service consumption  Detecting subscriber frauds  Mobile Money related Frauds (Phishing attacks)  Detecting Tethering of Smart Phones  Detecting Proxy Services  Achieving visibility on OTT services
  16. 16. 16 Using DPI to identify Fraud  Tethering performed in a commercial manner is considered to be an abusive operation and impacts the telecom operator in several ways: – Affecting the network planning and causing overloads – Could force the operator to invest in expanding his network – Harming the user experience of other legitimate users www ISP Backbone Legitimate connections Non-Legitimate connections Abusive tethering operation
  17. 17. 17 Quicker, Richer, Better  Cross analysis of non-correlated sources  Accurate, fast & intelligent insights  Reduction of time & investigation resources  Larger retention - storing for longer periods of time  Enabling RA & Fraud units to provide services and leverage capabilities for other non-fraud activities When Big Data Meets RA & Fraud
