Patent ID: 7788715

Claim:
A method performed by a server processor executing computer executable instructions stored in a computer readable memory device, the method comprising: receiving, at the server processor, a request from a client processor to establish a transmission control protocol (TCP) connection, wherein the TCP includes a link establishment phase and an authentication phase, wherein initiation of the link establishment phase occurs apart from the authentication phase, and wherein the receiving step and following steps occur during the link establishment phase; creating an extensible authentication protocol (EAP) session request to the client processor while still in the link establishment phase, wherein the client processor enters an authentication session with the server processor as a result of receiving the EAP session request; receiving a response from the client processor in response to sending the standard response; determining whether the response from the client processor indicates that the client processor will comply with the authentication session; and if the client processor will not comply with the authentication session then performing a substep of restricting access of the client processor.
