Survey on HMM based anomaly intrusion detection using system calls

Intrusion detection based on System calls is a very important domain of anomaly detection, this paper firstly introduces the basic idea of Hidden Markov Model (HMM) based intrusion detection, and then expounds its current development with comparisons about the merits and shortcomings to the current mainstream technologies, by the way, presenting some further discussions upon the future direction of the HMM-based intrusion detection.
