Description
The purpose of this control is to prevent information produced by the actions of a prior user, role, or the actions of a process acting on behalf of a prior user or role from being available to any current user, role, or process for obtaining access to a shared system resource (e.g., registers, main memory, or secondary storage) after the resource has been released back to the firewall. Control of information in shared resources is also referred to as object reuse. Verification of this function requires access to the internal programmer's documentation of the firewall manufacturer.
