Abstract:
1. A network security system for controlling access to an inner data system, said network security system comprising: an examination module for receiving a user access request to enter the inner data system, the user access request including a user name and password, checking the validity of the user name and password by the examination module, and generating an examination result that includes control instructions generated as a function of said checking; a redirect system for receiving and executing the control instructions generated by the examination module, wherein the control instructions will instruct the redirect system to transfer the user into the inner data system if the examination result shows that the user name and password are valid; and a reaction system for receiving the user access request from the redirect system when the examination result shows that the password is not valid, the reaction system being configured to respond to the user access request by providing response content which includes virtual data that has the same format as information contained within the inner data system, wherein the reaction system is further configured to record at least one successive action after the response content is transmitted from the reaction system, wherein the reaction system is further configured to execute one or more reaction programs designed to trace the IP address from which the user access request originated, and to send a Trojan code to the IP address from which the user access request originated, and wherein users are permitted only a limited number of attempts for the password, and according to the number of attempts at the password, the redirect system will direct an authorized user to an operating system associated with the inner data system and will direct an unauthorized user to the redirect system.
