Artificial Neural Network for Intrusion Detection Lixin Wang Synopsis An intrusion detection system mainly consists of two parts: anomaly detection and misuse detection. Anomaly detection is based on the assumption that observed activities deviate from expected normal system use. Misuse detection compares data against predefined patterns usually collected by an IDS signature database. One of the main shortcomings of misuse detection is that future attacks cannot be predicted or detected without predefining them in the IDS signature database. In this paper, we will focus on the study of the application of Neural Networks in the areas on misuse detection in order to detect known attacks and even variations of known attacks.
