A Proposed Machine Learning based Scheme for Intrusion Detection

Abstract

Voluminous data with high velocity and variety have resulted in deceiving the security of internet and intranet facilities. The threats are either having some patterns or lack any definite patterns. Therefore, the data arriving at the network have number of features and wide variety of patterns. Firstly, the number of patterns needs to be reduced and then the filtered set of patterns could be used for detecting unknown threats. This paper presents an approach for developing an Intrusion Detection System (IDS) with the help of Principal Component Analysis (PCA) and machine learning algorithms in WEKA environment. The approach yields better performance by making the detection more effective. The results show highertrue positive and lower false positive ratesin comparison to the existing methods.
