Authentication and access control are often combined into a single operation, so that access is approved based on successful authentication, or based on an anonymous access token. Authentication methods and tokens include passwords, biometric analysis, physical keys, electronic keys and devices, hidden paths, social barriers, and monitoring by ...
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.
Authentication, authorization, and accounting (AAA) is a framework used to control and track access within a computer network.. Authentication is concerned with proving identity, authorization with granting permissions, accounting with maintaining a continuous and robust audit trail via logging.
Identity management (ID management) – or identity and access management (IAM) – is the organizational and technical processes for first registering and authorizing access rights in the configuration phase, and then in the operation phase for identifying, authenticating and controlling individuals or groups of people to have access to applications, systems or networks based on previously ...
Password authentication uses secret data to control access to a particular resource. Usually, the user attempting to access the network, computer or computer program is queried on whether they know the password or not, and is granted or denied access accordingly. Passwords are either created by the user or assigned, similar to usernames.
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.
The earliest forms of Identity-based security was introduced in the 1960s by computer scientist Fernando Corbató. [4] During this time, Corbató invented computer passwords to prevent users from going through other people's files, a problem evident in his Compatible Time-Sharing System (C.T.S.S.), which allowed multiple users access to a computer concurrently.

In Windows, an access token is represented by the system object of type Token. An access token is generated by the logon service when a user logs on to the system and the credentials provided by the user are authenticated against the authentication database. The authentication database contains credential information required to construct the ...
