Hybrid role-based discretionary access control

摘要

A method for access control is provided. A request is received from an administrator to modify a user role for a user. Whether the user is in a user group that belongs exclusively to the administrator is determined. Whether the administrator role permits the request is determined in response to a determination that the user is in the user group. The user role is modified based on the request in response to a determination that the administrator role permits the request, wherein the user accesses a resource based on the user role.
