Abstract
A computing platformruns a compartmented operating systemand includes a trusted devicefor forming an integrity metric which a user can interrogate to confirm integrity of the operating system. Also, the integrity of an individual compartmentis verified by examining status information for that compartment including, for example, the identity of any open network connections, the identity of any running processes, and the status of a section of file space allocated to that compartment. Hence, the integrity of an individual compartmentof the compartmented operating systemcan be demonstrated.
