Although intrusion detection systems (IDS) are
essential to network defense, conventional signature-based
methods have poor flexibility to changing cyberthreats, high
false alarm rates, and restricted scalability. This study suggests
a hybrid ensemble machine learning-based Network Intrusion
Detection System (NIDS) that combines an Isolation Forest
model for unsupervised anomaly detection of unknown and
zero-day threats with a Random Forest classifier for supervised
detection of known attack types. Robust final classifications are
obtained by combining the results of the two models using a
weighted decision procedure. Additionally, the system includes a
full-stack web application with a comprehensive analytics
dashboard, GeoIP-based visualization, and real-time traffic
monitoring. Training and assessment are conducted using the
benchmark NSL-KDD and UNSW-NB15 datasets. The system
demonstrated its efficacy for practical implementation in
enterprise and cloud environments, achieving an accuracy of
99.97% with much lower false positive rates.
