The motivation +behind Asbestos is that typical access control systems are concerned +with the release of information, however, once that information is +released, the [[principal]] that released that information has no way to +control it. The problem is that a program might want to make use of +a service another program provides but not want to release the +information to it. To work around this, the OS provides the ability +to taint data. The taint is automatically applied to any derived +information. To propagate information outside of the machine, the +releaser must first untaint the information. This can only be done +with the original principal's authorization. + +Asbestos is described in Efstathopoulos et al.'s 2005 paper [Labels and +Event Processes in the Asbestos Operating System](http://pdos.csail.mit.edu/papers/asbestos-sosp05.pdf). |
