Abstract
A protection domain system is implemented to provide protection for applications executing in a computing environment. Protection domains are allocated system resources and may contain executing tasks. The protection domain system may allow tasks to access resources in other protection domains to which attachments have been made. Attachment is transparent to the software developer. The protection domain system provides flexibility in implementing operating system services and defining protection hierarchies.
