Abstract
An operating system for a computing device has a first session for a user that includes a first base process that has a first privileges token attached thereto. The first privileges token includes substantially a full set of privileges of the user on the operating system. The operating system also has a second session for the user that includes a second base process that has a second privileges token attached thereto. The second privileges token is derived from the first privileges token and includes only a minimum set of privileges of the user on the operating system. Thus, the second, limited token does not have all privileges associated with the first, full token but instead has a limited set of privileges and not extra privileges that could be employed to take actions that would be harmful, deceptive, or malicious.
