The OpenID Connect/OAuth 2 protocol is based on the OAuth 2.0 protocol, which provides secure authorization for requests to access resources. The central component it adds is identity verification, so that applications and services can ensure that users are who they claim to be before granting them access privileges or operating system privileges. Properly working with an identity implementation requires appropriate configuration steps such as proper implementation of TLS certificates, identity scopes, and data encryption methodologies in order to guarantee security during the user authentication process. This framework allows application developers and companies freedom from custom coding when integrating existing third-party APIs with their web-based products like single sign-on (SSO). In addition, this technology makes secure communications possible between different systems for exchanging data over the internet by relying on standards such as JWT tokens (JSON Web Tokens).
RBAC helps organizations to better define security policies for their applications and resources in the cloud, allowing them to group memberships based on functional roles or business needs. Using RBAC management tools, administrators can assign permissions by users or groups throughout the application environment and quickly revoke access rights if they no longer apply. With this control, environments with multiple tenants and teams can remain secure while keeping track of user access levels such as read/write/execute authority on all components of an application.
An app registration is a way of telling Azure AD about an application that needs to access AAD resources.
App registration is important to enable an application to integrate with Azure AD, and to obtain a client ID and client secret that can be used to authenticate the application with AAD.
The first step is to log in to the Azure portal and select Azure Active Directory from the left-hand menu.
You can specify the redirect URI in the “Redirect URI” section of the “Register an application” pane.
The client ID is used to identify your application when it authenticates with Azure AD.
The client secret is used to authenticate your application with Azure AD.
You can obtain the client ID and client secret by selecting “Certificates & secrets” from the left-hand menu and creating a new client secret.
The expiration date for a client secret is a security feature that allows you to set a time limit for the secret to be valid.
You can use the client ID and client secret to obtain an access token that allows your application to access AAD-protected APIs and resources.
The benefits of creating an app registration include better management of access to your application and ensuring that only authorized users have access to your resources.
