Abstract:

An integrity policy defines formal access constraints which, if effectively enforced, protect data from improper modification. The author identifies the integrity problems posed by a secure military computer utility. Integrity policies addressing these problems are developed and their effectiveness evaluated. A prototype secure computer utility, Multics, is then used as a testbed for the application of the developed access controls.
