Abstract

In today’s world, businesses and services are shifted to a digital transformation. As a result, network traffic has tremendously increased over the years. With that, network threats and attacks are growing and therefore, the importance of the Network Intrusion Detection System(NIDS) has increased. The traditional signature-based approach to intrusion detection is not sufficient to detect intrusions, so anomaly-based intrusion detection came into play. There are many methods to anomaly-based intrusion detection that can classify unknown network attacks. To detect network anomalies, Machine Learning and Deep Learning techniques are applied, and a considerable number of studies are done in this field. This paper presents classification models built using supervised Machine Learning algorithms. This study was conducted using algorithms like: Logistic Regression, Support Vector Machine (SVM), K-Nearest Neighbour (KNN), Naïve Bayes, Decision Tree and Random Forest on multiple subsets of a realistic evaluation dataset i.e. CICIDS-2017. The result from this study shows that Random Forest outperforms other supervised Machine Learning algorithms with accuracy rate as high as 99.93% with 14 features selected using Pearson’s correlation coefficient method.
