Is the reference monitor concept fatally flawed? The case for the negative

The reference monitor (RM) model has passed the critical test imposed by the methodology of science: it has been a productive concept for the field of computer security since its introduction. The call to abandon a productive model, however intellectually stimulating, should not be heeded simply for the sake of novelty.

We urge our readers and listeners to embrace the following conclusions, favoring dismissal of the resolution: first, that claims that the RM model is fundamentally flawed must be based on more than wishful thinking or technical frustration. Second, that radical claims for “new paradigms” be subjected to the usual degree of skepticism unless accompanied by compelling proofs of concept
