Abstract

The complexity of the cyber threats dictates the need for strong, privacy-preserving
mechanisms for anomaly detection. This paper introduces a new framework called BAFL, an
integration of Isolation Forest and Variational Autoencoders combined with Differential
Privacy, for safe and scalable solutions in cybersecurity applications. Federated Learning
allows distributed training across numerous clients without exposure of sensitive information,
while the blockchain technology introduces trust and integrity in model updates.
