Abstract: A method provides for control of access to network resources. A virtual identity machine resides in the network and is pre-authorized to access certain network resources. End users desiring access to those network resources attempt to logically connect to the virtual identity machines. If the logical connection attempt is successful, then the end user assumes the virtual identity of the virtual identity machine and has access to all of the same information that was available to the virtual identity machine.
