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]
AGDLP (an abbreviation of "account, global, domain local, permission") briefly summarizes Microsoft's recommendations for implementing role-based access controls (RBAC) using nested groups in a native-mode Active Directory (AD) domain: User and computer accounts are members of global groups that represent business roles, which are members of domain local groups that describe resource ...
The main alternative to the ACL model is the role-based access-control (RBAC) model. A "minimal RBAC model", RBACm, can be compared with an ACL mechanism, ACLg, where only groups are permitted as entries in the ACL. Barkley (1997) [19] showed that RBACm and ACLg are equivalent.
RBAC models generally treat the role hierarchy as either a tree (set theory), as in the 1992 RBAC model of Ferraiolo and Kuhn (FK), or a partially ordered set in the 1996 RBAC framework of Sandhu, Coyne, Feinstein, and Youman (SCFY). In object oriented programming terms, the tree role hierarchy is single inheritance, while the partial hierarchy ...
ABAC policy rules are generated as Boolean functions of the subject's attributes, the object's attributes, and the environment attributes. [ 3 ] Unlike role-based access control (RBAC), which defines roles that carry a specific set of privileges associated with them and to which subjects are assigned, ABAC can express complex rule sets that can ...
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 ...
In contrast to role-based access control (RBAC), which defines roles that carry a specific set of privileges associated with them and to which subjects are assigned, [4] ReBAC (like ABAC [5]), allows defining more fine-grained permissions. [4]
The eXtensible Access Control Markup Language (XACML) is an XML-based standard markup language for specifying access control policies. The standard, published by OASIS, defines a declarative fine-grained, attribute-based access control policy language, an architecture, and a processing model describing how to evaluate access requests according to the rules defined in policies.
