Attribute-Based Access Control (ABAC) is a flexible access control method that uses attributes such as user roles, locations, and times of access to dynamically determine who gets to see what and when. This allows for more nuanced, data-driven policies that adapt to different access needs and risk profiles. ABAC examples across various sectors include corporate data access, healthcare, finance, government information systems, cloud services management, education and research portals, and e-commerce customer management. To effectively implement ABAC, it is crucial to define attributes clearly, establish attribute sources, create a policy model, and monitor and adjust policies over time.
