1 results about "Distributed intrusion detection" patented technology

This invention discloses a distributed intrusion detection method and system based on flexible, secure, and trusted federated learning, belonging to the field of network data security and sharing. The method includes: dividing nodes into training nodes and aggregation nodes; training nodes collecting network traffic, training a local network traffic classification model, and sending it to an edge network device; the edge network device detecting the uploaded local model and updating the list of trusted and malicious nodes; aggregation nodes aggregating qualified local models and returning the generated global model to the edge device; the edge device receiving the global model, verifying it, and broadcasting it; all training nodes receiving and using the latest global model to obtain the final intrusion detection model, and using the final intrusion detection model to detect intrusions. This invention effectively improves the system's security and robustness while ensuring data privacy and the trustworthiness of sharing.
