With the improvement of the digital era comes an increased value for cybersecurity, and this needs to be addressed using advanced techniques. In this paper, we present an Intrusion Detection System (IDS) that combines the strengths of Convolutional Neural Networks (CNN) and Long Short-Term Memory (LSTM) networks, further optimized using Particle Swarm Optimization (PSO). The goal is to detect traffic patterns. The CNN components extract spatial features from the input data, while the LSTM captures the sequential dependencies, enhancing the detection of complex attack patterns. PSO is employed to automatically tune critical hyperparameters such as the number of LSTM units and dropout rate, improving both speed and classification accuracy. Experimental results demonstrate that the optimized model achieves an accuracy of 97.63%, outperforming traditional machine learning and non-optimized deep learning approaches. The proposed system provides a scalable and efficient solution for real-time intrusion detection in cyber environments.
