We describe a method that centrally manages Attribute-Based Access Control (ABAC) policies and locally computes and enforces decisions regarding those policies for protection of resource repositories in host systems using their native Access Control List (ACL) mechanisms. The method is founded on the expression of an ABAC policy that conforms to the access control rules of an enterprise and leverages the ABAC policy expression by introducing representations of local host repositories into the ABAC policy expression as objects or object attributes. Repositories may be comprised of individual files, directories, or other resources that require protection. The method further maintains a correspondence between the ABAC representations and repositories in local host systems. The method also leverages an ability to conduct policy analytics in such a way as to formulate ACLs for those representations in accordance with the ABAC policy and create ACLs on repositories using the ACLs of their corresponding representations. As the ABAC policy configuration changes, the method updates the ACLs on affected representations and automatically updates corresponding ACLs on local repositories. Operationally, users attempt to access resources in local host systems, and the ABAC policy is enforced in those systems in terms of their native ACLs.
