- Abstract
In this study, we constructed a method for obtaining information that explains the classification results of a long short-term memory (LSTM) trained as an intrusion detection system (IDS). The LSTM learns two types of information: information about system accesses at each time point and time series information across multiple time points. We extracted explanatory information to rank the importances of these two information types. If the time series information was considered more important, we extracted information indicating which range of past information influenced the classification.
