abstract = {The rapid growth of cloud computing has significantly increased the volume, velocity, and complexity of network traffic, creating new challenges for effective intrusion detection. Traditional signature-based and statistical anomaly-based Intrusion Detection Systems (IDS) are limited in detecting zero-day attacks, handling evolving threat patterns, and maintaining scalability in dynamic multi-tenant cloud environments. To address these limitations, this paper proposes an optimization-driven machine learning framework for cloud-based intrusion detection. The proposed system integrates embedded feature selection to reduce high-dimensional traffic attributes, Synthetic Minority Over-sampling Technique (SMOTE) to mitigate severe class imbalance, and a hybrid classification architecture combining Random Forest (RF) and Bi-directional Long Short-Term Memory (Bi-LSTM) networks. The feature selection mechanism enhances computational efficiency by eliminating redundant attributes, while synthetic sampling improves detection capability for minority attack classes. The hybrid model leverages ensemble-based classification and temporal sequence learning to capture complex traffic behaviours associated with multi-stage attacks. Experimental evaluation conducted on the CIC-IDS2017 benchmark dataset demonstrates strong classification performance with improved recall and reduced false positive rates, supporting the suitability of the proposed framework for real-time intrusion detection in cloud environments.},
