Abstract: A permissions provisioning module includes a data adapter and a permissions calculator associated with a policy evaluator operable to evaluate an ABAC policy. The module is adapted to interact with a computer system including resources, metadata and an access control mechanism enforcing, in respect of each resource, an access control list associated with the resource. In operation, the data adapter receives metadata for said computer system and assigns values to attributes in the policy based on the metadata. The permissions calculator queries the policy evaluator on combinations of resources and principals of the system using the attribute values thus assigned, and returns permission data. The data adapter formats said permission data into ACLs, for deployment in the computer system.

Abstract: An attribute-based access control (ABAC) policy governs the behaviour of an access control mechanism in a computer system which selectively permits and denies access to resources in the system. An administrator interface includes graphical elements that are responsive to user manipulation in such manner as allow the ABAC policy to be inspected and/or edited. In an online editing mode, a user's manipulations of the graphical representation have a direct effect on the behaviour of the access control mechanism.
