The adoption of the fifth-generation (5G) networks has come with revolutionary opportunities for network slicing, enabling various virtualized networks to coexist on the same infrastructure. Nevertheless, this proliferation of new technology has greatly increased the attack surface which exposes critical vulnerabilities including cross-slice attacks, resource exploitation, and unauthorized access. This paper focuses on AI-based threat detection systems that are specifically engineered to secure 5G network slicing architectures that are implemented in the hybrid cloud environments. The study uses a Transformer-based intrusion detection system with multi-head self-attention mechanisms to solve the upcoming security threats that are expected in the scenario of attack in 2026. The model was trained and tested on the 5G Network Intrusion Detection Dataset (5G-NIDD), achieving superior performance in the multi-class classification task, which involves both attack detection and the classification of the type. A comparison and analysis with the baseline models which comprise the Convolutional Neural Networks (CNN), Long Short-Term Memory networks (LSTM), ensemble Autoencoder-Support Vector Machines (AE-SVM), and Gradient Boosting discovered that the Transformer-based system had the highest detection accuracy of about 98.2% with an attack recall of 96.5%. The paper provides repeatable experimental procedures, complete performance indicators, and feasible suggestions on how AI-oriented security solutions can be incorporated into the functioning 5G networks. Future research directions include improving model interpretability through attention visualization and exploring federated learning to share threat intelligence among operators.
