Authorization

What is authorization?

Authorization refers to the process of determining what an authenticated user is allowed to do within a system. While authentication answers the question “Who are you?”, authorization answers “What can you access?” System authorization ensures that users only interact with resources and perform actions that match their assigned permissions or roles.

How authorization works

Authorization typically occurs after successful authentication. Once a user’s identity is confirmed, the system checks their permissions against an access control policy.

Common models include:

• Role-based access control (RBAC): Permissions are grouped by roles (e.g., admin, editor, viewer).

• Attribute-based access control (ABAC): Decisions are based on user attributes, resource attributes, and context.

• Policy-based access control: Uses predefined rules to grant or deny access.

These models help organizations enforce security and compliance by limiting access to sensitive data and functions.

Why authorization is important

Authorization protects critical resources from misuse or exposure. Without proper authorization, even authenticated users could access confidential data or perform actions beyond their scope, leading to security breaches and compliance violations.

Strong authorization practices:

• Reduce insider threats

• Support regulatory requirements

• Maintain operational integrity

As businesses adopt cloud services and remote work, authorization becomes vital for managing access across distributed environments.
