What is ABAC?
Attribute-Based Access Control is a flexible access model that makes authorization decisions by evaluating a set of attributes rather than fixed roles. These attributes can include the user’s department, job title, security clearance, the sensitivity of the resource being accessed, the time of day, or the location of the request. Unlike role-based access control which assigns permissions by job role alone, ABAC allows organizations to create highly granular and dynamic policies for example, allowing a finance manager to access payroll data only during business hours from a company-managed device. ABAC is particularly valuable in complex environments where a one size fits-all role structure is insufficient.
