Abstract

Multi-cloud deployments face significant security challenges due to fragmented visibility and regulatory constraints on data sharing. This paper proposes a novel Federated Learning (FL) framework for privacy-preserving anomaly detection across heterogeneous cloud environments. The proposed approach combines adaptive federated aggregation (AFA) with a hybrid CNN-LSTM model, differential privacy, and homomorphic encryption to address non-IID data distributions, communication overhead, and privacy risks. Evaluations using synthesized AWS, Azure, and GCP workload traces demonstrate 92.3% F1-score (13.7% improvement over FedAvg) while reducing communication overhead by 63% and resisting model inversion attacks with ε=1.0 differential privacy. The framework maintains compliance with GDPR/HIPAA by design, eliminating raw data transmission. Comparative analysis reveals 28% faster convergence than centralized approaches in asymmetric network conditions, establishing FL as a viable paradigm for cross-cloud security analytics.
