Attribute-Based Access Control

Attribute-Based Access Control (ABAC) grants access based on user, resource, and environmental attributes rather than predefined roles. Unlike RBAC, which assigns permissions based on roles, ABAC evaluates conditions like user department, device, location, and time. Key elements include user, resource, environmental, and session attributes. ABAC enables fine-grained access control, dynamic policy enforcement, and enhances security in Zero Trust environments. In Keycloak, it is implemented through JavaScript-based policies, resource attributes, and evaluation contexts, allowing for highly customizable access policies.Trendig glossary trems
