What is Attribute Based Access Control (ABAC)?

Attribute-Based Access Control (ABAC) is an access control paradigm where access rights are granted to users based on a combination of attributes. These attributes can be associated with the user, the resource being accessed, the environment, and even the action being performed. ABAC provides fine-grained control over access to resources compared to traditional role-based access control (RBAC) and is commonly used in scenarios where complex access policies are required, such as healthcare, finance, and government.
