Abstract

A system and method for granting access to a computer network. The method may include, for example, receiving at an access controller a request by a user to access the network using a computing device; providing the user with the option to retrieve a login page if authentication is required prior to network access being granted; using the access controller to verify user credentials provided by the user on the login page, the using the access controller to verify user credentials comprising: comparing a source IP address of a transmission control protocol connection request with a locally defined list of authorized user credentials stored in the access controller; and determining whether a White List associated with the access controller comprises a destination IP address; and granting the user access to the network if the user credentials are verified.

Claims12

Dependent claims

A method for granting access to a computer network, comprising:

receiving at an access controller a request by a user to access the network using a computing device, the request by the user including a transmission control protocol (TCP) connection request having a source IP address and a destination IP address;
determining by the access controller whether the user must login to access the network, including
comparing the source IP address with a list of logged in users stored in the access controller, wherein if the source IP address is included on the list of logged in users the user is granted access without logging in, and if the source IP address is not included on the list of logged in users, then
determining whether the destination IP address is included in a White List associated with the access controller, wherein if the destination IP address is included in the white list the user is granted access without logging in, and if the destination IP address is not included in the white list, then;
the access controller determines the user must login to access the network and provides the user with an option to retrieve a login page;
using the access controller to verify user credentials provided by the user on the login page;
and
granting the user access to the network if the user credentials are verified.

5 more elements

A system for providing network access to a user comprising:

a computing device that requests access to the network, the request including a transmission control protocol (TCP) connection request having a source IP address and a destination IP address;
and
an access controller connected to the computing device by a communication link that receives the request and provides to the computing device a link used for retrieving a login page if it is determined that authentication is required prior to network access being granted based on
comparing the source IP address with a list of logged in users stored in the access controller, wherein if the source IP address is included on the list of logged in users the user is granted access without logging in and if the source IP address is not included on the list of logged in users, then
determining whether the destination IP address is included in a White List associated with the access controller, wherein if the destination IP address is included in the white list the user is granted access without logging in, and if the destination IP address is not included in the white list, then the access controller grants network access to the computing device after the user credentials entered into the login page have been verified.
