What is the difference between policy-based authorization and authorization requirement?


Asked by Gordon Reeves on Nov 29, 2021 FAQ



An authorization requirement is a collection of data parameters that a policy can use to evaluate the current user principal. In our "AtLeast21" policy, the requirement is a single parameter—the minimum age.
Just so,
The policy-based model consists of three central concepts: policies, requirements, and handlers. A requirement is a collection of data parameters used by the policy to evaluate the user Identity
One may also ask, Policy-based authorization in ASP.NET Core. Underneath the covers, role-based authorization and claims-based authorization use a requirement, a requirement handler, and a pre-configured policy. These building blocks support the expression of authorization evaluations in code. The result is a richer, reusable, testable authorization structure.
Besides,
We define Authentication as “we know you are who you say you are.” On the other hand, we define Authorization as “we know what you’re allowed to do”. I imagine you’re familiar with role-based authorization. Role-based authorization simply states that we allow access based on the authenticated user’s roles. Users with a matching role have access.
Also Know,
A role-based authorization layer can be built around two roles—user and admin—defining which controllers and methods each group can access. You run into problems when it comes to overrules subtle distinctions that describe what users can or cannot do within a given role. For example, you may have users who enjoy access to back office systems.
