Attribute-based access control (ABAC) supports various granular and dynamic access control requirements, such as allowing managers to reschedule but not delete appointments (A) and enabling bakers with a rating of 4 or better to add recipes to the database (D). ABAC uses attributes (such as user roles, data characteristics, and environmental conditions) to define access control policies, providing a flexible and context-aware mechanism to enforce security policies tailored to specific business requirements.Reference: Pega Community documentation on ABAC and its use cases.
