Centralized authorization refers to an access control model where a single, unified database is used to manage and control user access rights across an entire organization. This approach allows for efficient administration since all access permissions and roles are managed from one location, reducing the risk of inconsistent permissions and providing a clear overview of who has access to what resources.

The primary advantage of centralized authorization is that it streamlines the management process, making it easier to implement security policies, conduct audits, and enforce access controls consistently. With a centralized system, administrators can quickly revoke or modify access permissions for users as needed without having to update multiple databases or systems, which is common in decentralized environments.

In contrast, decentralized authorization would imply multiple databases or systems managing access controls independently, which can lead to increased complexity and potential security vulnerabilities. Other options like role-based and task-based authorization specify how roles or tasks apply to users but do not inherently denote the centralized management aspect that is the hallmark of centralized authorization.
