Abstract:
1. A method for restricting access to one or more resources within a computer network, comprising the steps of: assigning a unique user identifier to each authorized human user of the computer network; retrieving the unique user identifier associated with a respective authorized human user logged into a source node; upon initiation of a TCP/IP communication attempt at the source node, wherein the TCP/IP communication attempt is associated with a request by the respective authorized human user for access to a specific resource within the computer network, wherein the TCP/IP communication attempt includes a synchronization packet having a header, inserting the unique user identifier assigned to the respective authorized human user logged into the source node into the header of the synchronization packet; intercepting the synchronization packet within the computer network without allowing the TCP/IP communication attempt to proceed; extracting the unique user identifier from the header of the synchronization packet; identifying the respective authorized human user logged into the source node based on the extracted unique user identifier; determining whether the respective authorized human user is authorized to access the specific resource; and if the respective authorized human user is authorized to access the specific resource, allowing the TCP/IP communication attempt to proceed and granting the respective authorized human user access to the specific resource at a destination node within the computer network.
