Abstract

In this work, we perform packet stream analysis using the Deep Temporal Point Process. The Deep Temporal Point process is a probabilistic generative model, which is used as a model that learns a pattern of a series of events and predicts the occurrence of future events (Saha et al., 2019). Instead of using this model as a generative model, we intend to use it for classification through learning event sequence patterns. To perform packet stream analysis, we use the packet arrival time among the raw data of the packets, which is regarded as the event occurrence time from the TPP point of view and learned. The time sequence input data is output as a probability distribution through the intensity function. Data from one attack category is trained for each model, and the classification task is performed by comparing the difference in likelihood from other models. Finally, we compare the performance between the used model and the new model that applies NTPP to packet stream analysis.
