ON THE LEARNING OF SYSTEM CALL ATTRIBUTES FOR HOST-BASED ANOMALY DETECTION
Gaurav Tandon, Philip K. Chan · International Journal of Artificial Intelligence Tools · 2006
Traditional host-based anomaly detection systems model normal behavior of applications by analyzing system call sequences. The current sequence is then examined (using the model) for anomalous behavior, which could correspond to attacks. Though these techniques have been shown to be quite effective, a key element is missing – the inclusion and utilization of the system call arguments. Recent research shows that sequence-based systems are prone to evasion. We propose an idea of learning different representations for system call arguments. Results indicate that this information can be effectively used for detecting more attacks than traditional sequence-based techniques, with reasonable storage and computational overhead.
