Which type of authorization is characterized by a core policy that manages user access?

Centralized authorization is a system where a core policy governs and manages user access consistently across the organization. This means that there is a single point of control for determining who has access to what resources, allowing for uniformity in how access rights are assigned and enforced.

The advantage of centralized authorization is that it simplifies management and enhances security by providing a clear and consistent framework for access control. With centralized authorization, any changes to user access, whether granting or revoking, can be managed from one central authority, reducing the likelihood of miscommunication or errors that may occur with multiple, disparate systems.

This differs from decentralized authorization, where control is spread across various departments or regions, potentially leading to inconsistencies and complicating the management of access rights. Automatic authorization typically refers to systems that grant access automatically based on predefined criteria without human intervention, while implicit authorization relies on inherited rights rather than a formal policy. Thus, the distinguishing factor of centralized authorization is the establishment of a central policy that standardizes access management.
