The user-based access methods work by authorizing specific users to connect to the server. When a client establishes a connection to a server, it has to prove being controlled by an authorized user. The two methods based on authenticating users using networked identity management systems are SUN-DES-1 and MIT-KERBEROS-5 .
Access Control Service, or Windows Azure Access Control Service (ACS) was a Microsoft-owned cloud-based service that provided an easy way of authenticating and authorizing users to gain access to web applications and services while allowing the features of authentication and authorization to be factored out of the application code.

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.
The AAA server in the CDMA wireless data network architecture is similar to the HLR in the CDMA wireless voice network architecture. Types of AAA servers include the following: Access Network AAA (AN-AAA) : Communicates with the RNC in the Access Network (AN) to enable authentication and authorization functions to be performed at the AN.
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.
Attribute-based access control (ABAC), also known as policy-based access control for IAM, defines an access control paradigm whereby a subject's authorization to perform a set of operations is determined by evaluating attributes associated with the subject, object, requested operations, and, in some cases, environment attributes.
CAS allows multi-tier authentication via proxy address. A cooperating back-end service, like a database or mail server, can participate in CAS, validating the authenticity of users via information it receives from web applications. Thus, a webmail client and a webmail server can all implement CAS.
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 ...
