A system for controlling access to a protected network includes a network access control module that is coupled to the protected network and which is configured to restrict access to the network to an authorized user through a computer coupled to the protected network. The system also includes a communication device associated with the computer, which automatically transmits a unique identifier corresponding to the communication device to the network access control module when a user uses the communication device to request access to the protected network via the computer. When the network access control module receives the unique identifier, the network access control module is configured to authenticate the communication device based on the unique identifier, to authenticate the user via the communication device when the communication device is authenticated, and when the user is authenticated, to submit log-on information directly to a log-on interface of the computer associated with the communication device so that the user can access the protected network via the computer.
