Motlatso Mokoele, Sello Mokwena . Comparative Analysis of Tree-based Intrusion Detection Modelling and Machine Learning Classification Models using Cyber-Security Dataset. International Journal of Computer Applications. 186, 13 ( Mar 2024), 33-40. DOI=10.5120/ijca2024923480
One of the critical problems organizations encounters is the increasing prevalence of cyber-criminals exploiting vulnerabilities, leading to identity theft. This breach of privacy not only threatens the organization’s financial assets, but can also have long-lasting consequences such as damaged reputations and legal implications. To address these issues, the study presented a thorough comparative analysis between tree-based intrusion detection model and popular machine learning classifiers using the well-established KDD99 dataset. The approach leverages a hybrid feature selection method, integrating the Gini index and information gain within a decision tree framework to enhance model efficiency. Evaluation metrics encompass precision, F1 score, confusion matrix, precision, recall, and execution time. Rigorous dataset preprocessing eliminates noise and biases. The findings reveal nuanced insights into model strengths and weaknesses, emphasizing the efficacy of the hybrid feature selection method in tree-based models. This study offers valuable guidance for cybersecurity professionals, helping to select models based on specific performance criteria. Ultimately, the research contributes to the advancement of intrusion detection techniques, highlighting potential areas for further exploration and improvement in the pursuit of more efficient and accurate intrusion detection systems.
