Oracle Solaris Security for Developers Guide

Privileged Applications

A privileged application is an application that can override system controls and check for specific user IDs (UIDs), group IDs (GIDs), authorizations, or privileges. These access control elements are assigned by system administrators. For a general discussion of how administrators use these access control elements, see Chapter 8, Using Roles and Privileges (Overview), in System Administration Guide: Security Services.

The Solaris OS provides developers with two elements that enable a finer-grained delegation of privileges:

The difference between authorizations and privileges has to do with the level at which the policy of who can do what is enforced. Privileges are enforced at the kernel level. Without the proper privilege, a process cannot perform specific operations in a privileged application. Authorizations enforce policy at the user application level. An authorization might be required for access to a privileged application or for specific operations within a privileged application.
