Generative AI and Federated Learning (FL) address these gaps by enabling anomaly detection, synthetic traffic generation, augmentation and imputation, adversarial traffic creation, and IDS alert explanations. The survey reviews representative IDS directions, organizes generative applications by model families and objectives, and studies integrations with FL while outlining key open challenges.","Generative AI and Federated Learning for Intrusion  \nDetection Systems: A Survey  \nJiefei Liu, Abu Saleh Md Tayeen, Pratyay Kumar, Qixu Gong, Wenbin Jiang, Huiping Cao, Satyajayant Misra, Jayashree Harikumar  \narXiv :2607 .0 1305v 1 [ cs .CR] 1 Jul 2026  \nAbstract—Intrusion Detection Systems (IDSs) are essential for monitoring network traffic and identifying malicious activities in modern cyber-physical, Internet of Things (IoT), enterprise, and distributed network environments. However, developing reliable IDS models remains challenging because attack behaviors evolve over time, realistic datasets are difficult to obtain, traffic records may be incomplete, attack classes are often imbalanced, and privacy constraints limit centralized data collection. Recent advances in generative artificial intelligence (AI) and Federated Learning (FL) provide new opportunities to address these limitations. Generative models can support anomaly detection, synthetic traffic generation, data augmentation, data imputation, adversarial traffic generation, and IDS alert explanation. FL enables distributed IDS training without directly sharing local network traffic, making it suitable for privacy-sensitive and geographically distributed environments.  \nThis survey provides a structured review of generative AI and FL techniques for IDS. We first summarize representative IDS research directions, including adversarial machine learning, anomaly-based detection, IoT-oriented IDS, explainable IDS, and benchmark datasets. We then categorize generative AI applications in IDS according to model families and task objectives, covering autoencoder-based models, Generative Adversarial Networks (GANs), diffusion models, and Large Language Models (LLMs). Finally, we review emerging studies that integrate generative AI with FL-based IDS and discuss open challenges, including synthetic data quality, realistic traffic generation, dual-use adversarial risks, non-IID client distributions, communication-efficient model sharing, federated IDS benchmarking, and domain-specific LLMs for network security.  \nIndex Terms—Intrusion Detection System, Generative AI, Federated Learning, Network Security, Synthetic Data Generation, Large Language Model.  \nI. INTRODUCTION  \nModern computer networks support a wide range of critical services, including cloud computing, Internet of Things (IoT) platforms, industrial control systems, intelligent transportation, financial systems, healthcare infrastructure, and defense applications. As these systems become increasingly connected, they also become more exposed to cyber attacks that can disrupt services, compromise sensitive data, or damage physical infrastructure.

An IDS monitors system activities or network traffic and identifies behaviors that may indicate unauthorized access, malware propagation, denial-of-service attacks, data exfiltration, or other malicious activities. Early IDS research established the foundation for monitoring security-relevant events and detecting abnormal system behaviors [1], [2] . Since then, IDS techniques have evolved from rule-based and signature-based detection toward data-driven approaches based on machine learning (ML) and deep learning (DL) .
