HP-UX RBAC Architecture

The primary component of HP-UX RBAC is the privrun command, which invokes existing commands, applications, and scripts. The privrun command uses the ACPS subsystem to make access control requests. An access request is granted or denied based on a set of configuration files that define user-to-role and role-to-authorization mappings.

If the access request is granted, privrun invokes the target command with additional privileges, which can include one or more of either a UID, GID, fine-grained privileges, and compartments. The privileges are configured to enable the target command to run successfully.

Figure 3-1“HP-UX RBAC Architecture” illustrates the HP-UX RBAC architecture.
