发明名称 Centralized security control system
摘要 A central security control system (security system) interfaces between a plurality of requesters and a plurality of destinations such that it receives from the requesters requests for access to the destinations and communicates to the destinations a level of access that should be granted to a requester by that destination on a per request basis. In a preferred embodiment the security system also a) authenticates the requester to a predetermined level from which the level of access that is to be granted is derived and b) causes a direct connection to be established between the requester and the destination.
