Our cube contains only the measures that we wish to be accessible to the Operations information consumers. We have succeeded in generating a fully functional "view" of the data, complete with all dimensions and the measures that we deemed appropriate, while securing the information that we sought to restrict. All that remains is to create two security roles for the Operations and Corporate groups, and to assign the Operations role to this cube, and the Corporate role to the original, unrestricted cube. We have augmented physical and other security through the use of a virtual cube that is quite simple to create, once the requirements and restrictions for the component roles is understood.
