Problems author has identified to resolve it:Three problems are identified as
- Privacy concerns (IP address reveals primarily the sensitive information)
- Anomaly variability (System can be failed in detection of lower anomaly intensities)
- Ground truth (Manual anomaly labeling being which involves biased-ness)
Synthetic generation of flow-level traffic traces approach has been proposed to use as an alternative. Because it does not include any sensitive information and contain anomalies of different types and intensities.
