Abstract: This paper explores a hybrid approach of intrusion detection through knowledge discovery from big data using Latent Dirichlet Allocation (LDA). We identify the "hidden" patterns of operations conducted by both normal users and malicious users from a large volume of network/systems logs, by mapping this problem to the topic modeling problem and leveraging the well established LDA models and learning algorithms. This new approach potentially completes the strength of signature-based and anomaly-based methods.
