Description: Model security refers to the measures implemented to protect machine learning (ML) models from unauthorized access and malicious attacks. In an environment where ML models are increasingly used to make critical decisions, security becomes a fundamental aspect. This includes protection against data manipulation, model theft, and exploitation of system vulnerabilities. Model security techniques range from data encryption and user authentication to implementing access controls and security audits. Additionally, it considers the robustness of the model against adversarial attacks, where the goal is to deceive the model through inputs specifically designed to induce errors. Model security not only protects the integrity of the model but also safeguards the privacy of the data used to train it, which is especially relevant in sectors like healthcare and finance. In summary, model security is an essential component in the lifecycle of machine learning models, ensuring that they operate safely and reliably in an increasingly threatening digital landscape.
