Abstract: One of the most significant requirements for improving the accuracy and performance of the detection engine in an intrusion detection system (IDS) is to identify and pick just the most important and relevant features. Due to the advancement of some ubiquitous technologies such as cloud computing, internet of things (IoTs), etc. large volumes of data are generated and shared in the network in every fraction of seconds that needs to be gathered and correctly analysed by the IDS. Although, every dataset consists of many features, altogether it may not contribute to identify legitimate traffic; therefore, reduction of irrelevant features and selection of only relevant attributes may enhance the accuracy and increase the speed of IDS. Thus, in order to eliminate the irrelevant features, we have proposed a features selection technique which recognises the important features and increase the performance of the detection engine based on the score of features establishment.
