AI Security refers to the protection of artificial intelligence systems from cyber threats, as well as the use of AI technologies to strengthen cybersecurity. This includes safeguarding AI models, data, and infrastructure from attacks such as data poisoning, model theft, or adversarial manipulation. At the same time, AI security also involves deploying AI-driven tools to detect, prevent, and respond to cyber threats more effectively. The term covers both securing AI itself and leveraging AI to enhance overall digital security.
