Authorization
Authorization is the process of determining what a verified user is permitted to do — what resources they can access, what actions they can perform, and what data they can view or modify. Authorization happens after authentication: first the system confirms your identity, then it checks what permissions your identity has been granted.
Authorization is implemented through access control mechanisms like role-based access control (RBAC), where permissions are assigned based on job roles, or attribute-based access control (ABAC), where access decisions consider multiple factors like user role, time of day, location, and data sensitivity.
Why It Matters
Proper authorization controls — ensuring users can only access what they need for their job — are a CMMC requirement under access control and least privilege principles. Overly permissive authorization is a common finding during assessments.
