In some cases permissions are implemented in 'all-or-nothing' approach: a user either has to grant all the required permissions to access the application or the user can not access the application. There is still a lack of transparency when the permission is used by a program or application to access the data protected by the permission 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.
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.

The use of attributes bring additional context to evaluate the legitimacy of any request for access and inform the decision to grant or deny access.

Whenever a subject attempts to access an object, the operating system kernel examines these security attributes, examines the authorization rules (aka policy) in place, and decides whether to grant access. A database management system, in its access control mechanism, can also apply mandatory access control; in this case, the objects are tables ...
Role-based access control is a policy-neutral access control mechanism defined around roles and privileges. The components of RBAC such as role-permissions, user-role and role-role relationships make it simple to perform user assignments. A study by NIST has demonstrated that RBAC addresses many needs of commercial and government organizations. [4]
