An apparently prevailing myth is that safety is undecidable in Discretionary Access Control (DAC); therefore, one needs to invent new DAC schemes in which safety analysis is decid...

We analyze the safety question for the Non-Monotonic Transform NMT model, an access control model that encompasses a wide variety of practical access control mechanisms. In genera...
