Abstract
A mechanism is disclosed for implementing file access control using labeled containers. With this mechanism, it is possible to implement file access control without storing a sensitivity label with each file, and without checking a sensitivity label each time a file is accessed. Rather, by virtue of the manner in which the containers are labeled, and the manner in which a portion of the file system of one container is incorporated into the file system of another container, file access is effectively controlled. Thus, with this mechanism, it is possible to implement file access control simply and efficiently.
