Abstract
The disclosed subject matter includes a method. The method includes identifying an attempt to access, by an application instance running in a user space of an operating system, a first security zone of a computer readable medium, where the first security zone is associated with a first security level. The method further includes determining whether a restriction level associated with the application instance is higher than the first security level, where the restriction level is a function of previous security zones that have been accessed by the application instance. When the restriction level associated with the application instance is higher than the first security level, the method would prevent the application instance from writing to the first security zone. When the restriction level associated with the application instance is not higher than the first security level, the method would authorize the application instance to access the first security zone.
