B.AMARNATH REDDY 1 ,SURENI.LAKSHMI SUPRIYA 2 03 06 The proposed work presents an enhanced network intrusion detection framework based on a hybrid Seq2SeqConvLSTM architecture integrated with Gated Recurrent Unit GRU and Bidirectional learning mechanisms Modern network environments generate large volumes of sequential traffic data containing complex temporal and spatial dependencies making accurate intrusion detection a challenging task To address these challenges the proposed model extends the conventional Seq2Seq ConvLSTM framework by incorporating GRU layers to improve computational efficiency and Bidirectional layers to capture contextual information from both past and future network traffic sequences The GRU component is employed to reduce the computational complexity associated with traditional recurrent neural networks while maintaining effective longterm dependency learning Compared with conventional LSTMbased architectures GRU requires fewer parameters resulting in faster training and inference times without sacrificing detection accuracy This enhancement enables the model to process largescale network traffic efficiently and supports realtime intrusion detection requirements To further improve feature representation Bidirectional recurrent layers are integrated into the architecture The Bidirectional mechanism processes network traffic sequences in both forward and backward directions allowing the model to learn comprehensive temporal relationships and capture sophisticated attack patterns that may not be effectively identified through unidirectional processing This capability enhances the detection of complex and evolving cyberattacks including previously unseen intrusion behaviors The proposed Bidirectional GRUIntegrated Seq2SeqConvLSTM framework combines sequencetosequence learning for feature encoding ConvLSTM layers for spatiotemporal pattern extraction and Bidirectional GRU layers for enhanced temporal dependency modeling A Flaskbased web application is developed to provide an interactive platform where users can upload network traffic datasets and obtain intrusion classification results in real time The system supports automated analysis and visualization of detection outcomes making it suitable for practical cybersecurity monitoring environments Experimental evaluation demonstrates that the proposed framework outperforms baseline Seq2Seq ConvLSTM and Random Forest models across multiple performance metrics including accuracy precision recall F1score and detection latency The results indicate improved robustness against diverse attack categories while maintaining efficient computational performance These findings suggest that the proposed Bidirectional GRUIntegrated Seq2SeqConvLSTM model offers a reliable scalable and effective solution for modern network intrusion detection systems operating in dynamic and securitycritical environments Copyright (c) Journal of Science Engineering Technology and Management Science.
