Some embodiments include a computer-implemented method for controlling access to resources of a platform in a computer system. The method can comprise detecting a request to access a resource, wherein the resource resides in the computer system, and wherein the resource is associated with an owner; requesting a first resource access decision from a first policy decision unit associated with the owner; receiving, from the first policy decision unit, the first resource access decision and first trust information, wherein the first trust information indicates trust of a second policy decision unit; requesting a second resource access decision from the second policy decision unit associated with the virtual universe platform; receiving, from the second policy decision unit, a second resource access decision; and returning the second resource access decision.
