This paper discusses our research in developing a generalized and systematic method for anomaly
detection. The key ideas are to represent normal program behaviour using system call frequencies
and to incorporate probabilistic techniques for classification to detect anomalies and intrusions.
Using experiments on the sendmail system call data, we demonstrate that concise and accurate
classifiers can be constructed to detect anomalies. An overview of the approach that we have
implemented is provided.
