Access control systems are important in regulating who can access physical facilities , computer systems, and data resources. However, traditional access control systems have limitations in adapting to changing user behavior and evolving security threats. We argue that applying machine learning is a promising direction to access control systems can enhance their accuracy, efficiency, and effectiveness. Machine learning can help identify and mitigate security risks in real-time by detecting patterns of suspicious activity that may indicate a security breach or attempted attack. It can also learn to identify anomalies and raise alerts, enabling security personnel to respond quickly and prevent potential security incidents.
