Enterprise Security Management System Using Hierarchical Organization and Multiple Ownership Structure

摘要

A hierarchical security model for networked computer users is described. Files and resources are controlled or created by users within the network. Each user within the network has an account that is managed by a network administrator. The account specifies the user identifier and password. Users are grouped into organizations depending upon function or other organizational parameter. The groups within the network are organized hierarchically in terms of access and control privileges. Users within a higher level group may exercise access and control privileges over files or resources owned by users in a lower level group. The account for each user further specifies the group that the owner belongs to and an identifier for any higher level groups that have access privileges over the user's group. All users within a group inherit the rights and restrictions of the group.
