Patent ID: 7861076

Claim:
A system for providing network security by enforcing unique bindings across an associated network, the system comprising: a plurality of network access devices; an authentication server communicatively coupled with the plurality of network access devices; a common security database coupled with the authentication server, the common security database operative to store data representative of username, calling station identifier, framed internet protocol address, and an identifier for an associated network access device; wherein each of the plurality of network access devices is responsive to a request from a user to access the associated network to obtain parameters associated with user including at least a username, a calling station identifier, and a framed internet protocol address, to send the obtained parameters with an identifier for the network access device receiving the request to the authentication server; wherein the authentication server is responsive to receipt of the parameters from the plurality of network access devices to store the parameters and the identifier for the network access device receiving the request for reach request as common security entries in the common security database; wherein the authentication server is configured to detect a conflicting entry in the common security database by comparing the common security entries with the obtained parameters to determine whether at least one of the obtained parameters were previously stored in the common security database is associated with at least one of the plurality of network access devices other than the network access device receiving the request to access the associated network; wherein a conflicting entry is detected when at least one of the group consisting of username, calling station identifier and framed internet protocol address is associated with more than one of the plurality of network access devices; wherein the authentication server is configured to send a message to a one of the plurality of network access devices coupled to a user associated with the conflicting entry responsive to the authentication server detecting the conflicting entry in the common security database; and wherein the message is one of a group consisting of a disconnect request and a change of authorization.
