Securing 5G Networks: A Deep Learning-Based Intrusion Detection Framework for Wireless Infrastructure

Abstract

With the fast development of 5G networks, the need to ensure that these networks are secured against cyber threats, which are advanced and constantly evolving, is of immense importance. In this paper, an intrusion detection system based on deep learning using a hybrid Convolutional Neural Network (CNN) and Long Short-Term Memory (LSTM) architecture is introduced to meet the security requirements of 5G wireless networks. The model also showed high accuracy, precision, and recall when training and testing on various publicly available datasets (CICIDS 2017 and NSL-KDD) by identifying different types of attacks, namely Distributed Denial of Service (DDoS), SQL Injection, and Advanced Persistent Threats (APT). Findings reveal that the CNN-LSTM model performs better compared to standard machine learning models such as Support Vector Machines (SVM) and Decision Tree, scoring high with regard to detection abilities and optimizing computing requirements. The model is an effective intrusion detection method in real-time despite training time and latency issues, it is a very useful solution to the fast-developing intrusion detection scenario involving the dynamic 5G network. The study offers an insight into the possibility of deep learning methods in boosting cybersecurity in 5G networks and lays the foundation for newer advances in network security systems.
