摘要: In this paper we present a new method to process sequences of system calls for anomaly intrusion detection. The key idea is build multi-layer model program behaviours based on both hidden Markov models and enumerating methods detection, which differs from the conventional single layer approach. Our experiments Unix sendmail have shown that better in detecting anomalous behaviour programs terms accuracy response time. As use temporal characteristics model, it suitable online host-based detection systems LAN environment. Index Terms Intrusion machine learning, call sequence.
