How to obtain traffic metadata from 5G networks cost efficiently?

• There’re costly ways to do it, but that’s unacceptable for consumers

• Cost level target for traffic metadata acquisition for traffic analysis-based protection is < 0.2 € per device per month

• Relevant network metadata to be used in ML and other algorithms:

• Traffic flows created and closed (Source & destination addresses and ports, IP protocol)

• Sliding window average bandwidth used per flow (uplink and downlink)

• Median of packet sizes in flows

• Inter-packet delay in flows

• In-flow packet median TTL

How to map 5G network traffic flows to user or device identities?

• Identity is needed in order to offer user-specific protection

• Identity should be pseudonymized for privacy and legal reasons

• Mapping needs to be real-time or near-real-time in order to provide near-real-time protection

How to block individual flows in 5G networks based on verdicts of detection algorithms?

• Blocking actions taken as response measures
