Data Preprocessing: Included label encoding, MinMax scaling, and handling of missing values to ensure data quality and model consistency.
Feature Engineering: Utilized TF-IDF, Bag-of-Words, Word2Vec for textual data, and Principal Component Analysis (PCA) for numerical features to capture rich information from network traffic.
Feature Selection: Recursive Feature Elimination (RFE) was employed to identify and retain the most critical features, reducing computational cost and improving model focus.
Near-Optimal Classification Results Achieved
Our models, particularly the PCA-M2-RNN configuration, demonstrated near-perfect performance on the UNSW-NB15 dataset. This includes achieving 100% across all critical metrics such as accuracy, precision, recall, F1 score, specificity, and AUC, showcasing robust detection capabilities.
100%
Recall achieved across proposed models, eliminating undetected threats in IoT environments.
The use of stratified fivefold cross-validation ensured a rigorous evaluation, confirming the models' stability and generalizability across different data partitions. This meticulous approach contrasts with prior studies often limited by small datasets or incomplete metric reporting.
The PCA-M2-RNN model, which combines PCA with the M2-RNN architecture (including dropout layers), proved to be the most effective, balancing computational efficiency with superior detection accuracy.
Outperforming Traditional Methods & Prior Research
The proposed framework surpasses the performance of traditional detection methods and many prior deep learning approaches in IoT malware detection. Our models consistently achieved higher and more balanced metrics, especially in critical areas like recall, which is vital for security applications.

The framework's lightweight architecture (20,801 trainable parameters) and moderate training/inference times make it suitable for real-world deployment in resource-constrained IoT systems, contributing to more transparent and trustworthy AI-driven cybersecurity solutions.
Future work involves validating the approach on additional datasets, exploring more advanced RNN architectures, and integrating explainable AI (XAI) techniques to further enhance transparency and analyst trust.
Real-World Deployment Potential
Our framework's compact design, utilizing relatively lightweight SimpleRNN layers and only 20,801 trainable parameters, ensures low computational overhead. This makes it ideal for integration into practical IoT security monitoring systems, like network intrusion detection systems (NIDSs), where timely detection and computational efficiency are paramount.
The experimentally validated performance, coupled with moderate training and inference times, signifies its potential for enhancing IoT malware detection against evolving threats in live environments, providing a balanced trade-off between performance and cost.
