What is attribute-based access control?

Attribute-based access control (ABAC) is an authorization model that grants access to resources based on attributes associated with the user, the resource, and the environment. It moves beyond traditional role-based access control (RBAC) by using policies that evaluate multiple attributes to make access decisions. These attributes can include user roles, security clearances, resource types, sensitivity levels, time of day, and location. ABAC allows for more fine-grained and dynamic access control than RBAC, enabling organizations to implement complex security policies and adapt to changing business needs.
