Abstract(in English) | The authors propose a general-purpose anomaly detection mechanism using Prefix Aggregate without Labeled data (GAMPAL) for Internet traffic. GAMPAL aggregates flows based on BGP (Border Gateway Protocol), and detects anomalies by comparing the predicted traffic flow for each aggregated group with the observed traffic flow. The model of the existing method is trained with time-series data of past flows as input and future values as output. In order to improve the accuracy of prediction and detection, this paper uses the flow rate as input and time-based features such as month, hour, minute, and day of the week, which are generated from the recorded date and time of each value, as output. This method enables to learn various temporal characteristics, such as weekly and daily. The evaluation results show that RFR (Random Forest Regressor) is the most suitable for the proposed learning method among LSTM-RNN (Long Short-Term Memory Recurrent Neural Network), RFR, and SVM (Support Vector Machine). The difference between predicted and observed flow size is reduced by 80.8% from our previous method. Computation time is also reduced. Furthermore, when connection failure for YouTube was occurring, the observed values are continuously much lower than the predicted values. It shows this method can detects anomalies. |
