Generally, the traditional Intrusion Detection Techniques can be categorized into anomaly detection or misuse detection. Based on the mechanism of computer immune system, this paper presents a new anomaly detection technique to detect intrusion into computer system. In this technique, a Markov chain model is used to represent a temporal profile of normal behavior of a process. The Markov chain model of normal profile can be created by learning the historic data of the sequence of system calls produced by privileged processes running on UNIX system.
