Federated learning security considerations involve protecting data privacy, ensuring secure communication among distributed devices, and defending against adversarial attacks. Key concerns include preventing data leakage, securing model updates, authenticating participants, and mitigating risks from poisoned or manipulated data. Techniques such as encryption, secure aggregation, differential privacy, and robust anomaly detection are employed to address these challenges, maintaining both confidentiality and integrity throughout the federated learning process.

What is federated learning and why is security important?
Federated learning trains a shared model across devices without centralizing raw data. Security is crucial to protect privacy, prevent leakage from model updates, and defend against attacks in a distributed setup.
How can data privacy be protected in federated learning?
Use privacy-preserving techniques such as secure aggregation to hide individual updates, apply differential privacy to add controlled noise, and encrypt data in transit and at rest.
How are model updates and communications secured in federated learning?
Ensure secure channels (e.g., TLS), protect updates with cryptography, and employ secure aggregation so the server cannot see single-user updates; advanced options include MPC or homomorphic encryption as needed.
What are common threats in federated learning and how are they mitigated?
Threats include data poisoning, model inversion, backdoors, and impersonation. Mitigations include robust aggregation, anomaly detection, strong participant authentication, and ongoing monitoring.
