This also allows an authorization server to present a centralized user interface for resource owners. Requesting Party (RqP) UMA defines requesting parties separately from resource owners. This enables party-to-party sharing and fine-grained delegation of access authorization. A resource owner need not consent to token issuance at runtime (i.e ...
In computer security, general access control includes identification, authorization, authentication, access approval, and audit.A more narrow definition of access control would cover only access approval, whereby the system makes a decision to grant or reject an access request from an already authenticated subject, based on what the subject is authorized to access.

For example, Diameter uses the URI scheme AAA, which also stands for "Authentication, Authorization and Accounting", as well as the Diameter-based Protocol AAAS, which stands for "Authentication, Authorization and Accounting with Secure Transport".

In computer security, an access-control list (ACL) is a list of permissions [a] associated with a system resource (object or facility). An ACL specifies which users or system processes are granted access to resources, as well as what operations are allowed on given resources. [1] Each entry in a typical ACL specifies a subject and an operation.
XACML is a policy-based, attribute-based access control authorization framework. It provides: An access control architecture. A policy language with which to express a wide range of access control policies including policies that can use consents handled / defined via OAuth. A request / response scheme to send and receive authorization requests.
Hence, access control in computer systems and networks relies on access authorization specified during configuration. Most modern, multi-user operating systems include role-based access control (RBAC) where authorization is implicitly defined by the roles. User authentication is the process of verifying the identity of consumers. When an ...
Its purpose is to permit a user to access multiple applications while providing their credentials (such as user ID and password) only once. It also allows web applications to authenticate users without gaining access to a user's security credentials, such as a password. The name CAS also refers to a software package that implements this protocol.
In the context of an HTTP transaction, basic access authentication is a method for an HTTP user agent (e.g. a web browser) to provide a user name and password when making a request. In basic HTTP authentication, a request contains a header field in the form of Authorization: Basic <credentials> , where <credentials> is the Base64 encoding of ID ...
