Abstract

A simple and general definition of denial ofservice in operating systems is presented herein.It is argued that no current protection mechanismnor model resolves this problem in any demonstrableway. A set of examples from known systems ispresented in order to delimit the scope of theproblem. The notion of interuser dependency isintroduced and identified as the common cause forall problem instances. Necessary end sufficientconditions for solutions are stated and justifiedinformally. The relative complexity of undesirable(and unspecified) interuser dependencies is alsodiscussed.
