Intrusion Detection System using Aggregation of Machine Learning Algorithms

With the advancement of internet technologies comes the need for systems that can ensure the security of a network. An intrusion Detection System (IDS) can detect and sometimes take action against malicious network traffic. There are different types of IDS. For example, based on the detection method, it can be Signature-based IDS or Anomaly-based IDS or Hybrid IDS. In this work, multiple models are trained using various machine learning algorithms on the NSL-KDD dataset to build an efficient anomaly-based IDS that can detect malicious traffic with utmost accuracy. Supervised Learning algorithms like Logistic Regression, Decision Tree, K-Nearest Neighbour (KNN), XGBoost, Random Forest and Multilayer Perceptron (MLP) are used. At last, the Hard Voting technique is employed to increase efficiency.
