Methods, systems, and computer program products for access control services using a transparent firewall in conjunction with an authentication server

摘要

Access control methods include receiving an access authorization message from an authentication server computer at a blocking device that connects a first network to a second network, modifying access criteria of a transparent firewall at the blocking device responsive to the received access authorization message and operating the transparent firewall according to the modified access criteria to control transfer of messages between the first and second networks. The invention may also be implemented as apparatus and computer readable media.
