Abstract

Intrusion detection is a critical component of secure information systems. This paper addresses the issue of identifying important input features in building an intrusion detection system (IDS). Since elimination of the insignificant and/or useless inputs leads to a simplification of the problem, faster and more accurate detection may result. Feature ranking and selection, therefore, is an important issue in intrusion detection.The important aspect of our technique is to identify key intrusion detection features that aid in achieving faster detection (real time detection) and higher accuracy rate (low false alarm rate).In this paper we rank the importance of input features using Neural networks by analyzing the detection accuracy, false positive rate and false negative rate. Results from the DARPA intrusion detection evaluation are provided. We also discuss our methodology for identifying important input features and provide the results obtained for five classes (normal, probe, denial of service, user to super-user and remote to local) for the DARPA dataset.
