  2. Role-based access control - Wikipedia

    en.wikipedia.org/wiki/Role-based_access_control

    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]

  3. Relationship-based access control - Wikipedia

    en.wikipedia.org/wiki/Relationship-based_access...

    The nodes and edges of this graph are very similar to triples in the Resource Description Framework (RDF) data format. [1] ReBAC systems allow hierarchies of relationships, and some allow more complex definitions that include algebraic operators on relationships such as union, intersection, and difference. [2]

  4. Graph-based access control - Wikipedia

    en.wikipedia.org/wiki/Graph-based_access_control

    The foundations of GBAC go back to a research project named CoCoSOrg (Configurable Cooperation System) [[1]] (in English language please see [2]) at Bamberg University.In CoCoSOrg an organization is represented as a semantic graph and a formal language is used to specify agents and their access rights in a workflow environment.

  5. Attribute-based access control - Wikipedia

    en.wikipedia.org/wiki/Attribute-based_access_control

    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 evaluate many different attributes. Through defining consistent subject and object attributes into security policies, ABAC eliminates the need ...

  6. RSBAC - Wikipedia

    en.wikipedia.org/wiki/RSBAC

    RSBAC means "ruleset based access control" and is also a role-based access control solution. The two acronyms can cause confusion. The two acronyms can cause confusion. In his essay "Rule Set Modeling of a Trusted Computer System", Leonard LaPadula describes how the Generalized Framework for Access Control (GFAC) approach could be implemented ...

  7. XACML - Wikipedia

    en.wikipedia.org/wiki/XACML

    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.

  8. Organisation-based access control - Wikipedia

    en.wikipedia.org/wiki/Organisation-based_access...

    In computer security, organization-based access control (OrBAC) is an access control model first presented in 2003. The current approaches of the access control rest on the three entities (subject, action, object) to control the access the policy specifies that some subject has the permission to realize some action on some object.

  9. Property graph - Wikipedia

    en.wikipedia.org/wiki/Property_graph

    Building upon widely adopted definitions, [2] [3] a property graph/attributed graph can be defined by a 7-tuple (N, A, K, V, α, , π), where N is the set of nodes /vertices of the graph; A is the set of arcs (directed edges) of the graph; K is a set of keys, taken from a countable set, defining the nature of attributes/properties
