Physical access control can be achieved by a human (a guard, bouncer, or receptionist), through mechanical means such as locks and keys, or through technological means such as access control systems like the mantrap ...
In computer systems security, Relationship-based access control (ReBAC) defines an authorization paradigm where a subject's permission to access a resource is defined by the presence of relationships between those subjects and resources. In general, authorization in ReBAC is performed by traversing the directed graph of relationships.
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]
The discretionary access control mechanisms of some operating systems can be used to enforce need to know. [2] In this case, the owner of a file determines whether another person should have access. Need to know is often concurrently applied with mandatory access control schemes, in which the lack of an official approval (such as a clearance ...
Research has used network analysis to examine networks created when artists are exhibited together in museum exhibition. Such networks have been shown to affect an artist's recognition in history and historical narratives, even when controlling for individual accomplishments of the artist.
The NIST RBAC model is a standardized definition of role-based access control.
