Network Anomaly Detection refers to the detection of abnormal network activities due to security breaches or other network issues. Traditional methods of detection often rely on known signatures of anomalies. More recently, the advancement of machine learning has become a more robust mechanism to address this issue. However, the nature of network anomaly detection directly contradicts with the notion of data privacy and confidentiality. Being able to detect anomalies while preserving the privacy of the data has become a hotly researched topic.This thesis proposes a privacy-preserving Random Forest classifier tailored for anomaly detection settings. The system leverages Fully Homomorphic Encryption (FHE) encryption to achieve privacy-preserving classification on encrypted data. This work improves the computation and communications costs compared to previous works. Furthermore, the system is hardware-accelerated by GPUs, resulting in a speedup of up to 160x over a single-threaded CPU. Importantly, the optimization techniques place special emphasis on the scalability of the overall system, so that it can process higher throughput by horizontally scaling the hardware resources. This thesis also proposes a client-server-based protocol for generic random forest predictions, suitable for use cases such as Machine-Learning-as-a-Service (MLaaS).The privacy-preserving Random Forest was evaluated by common classification metrics on a network detection dataset, CIC-DS-2017. Experiments have shown that our system is able to sustain a detection throughput of 15 Kbps with high detection accuracy (F1 > 0.90) on a system with an Nvidia A100 GPU.
