ABSTRACT:
A system and method is presented for analyzing information in a communication line for unwanted intrusions and for allowing information to be transmitted back into the communication line without disrupting the communication traffic when an intrusion is detected. The system and method includes a security tap connected to a firewall. The security tap is also connected to an intrusion detection device. The intrusion detection device analyzes the information in the communication line for indicia of attempts to compromise the network. When such indicia is detected, the intrusion detection device sends a “kill” data packet back through the security tap and directed back to the communication line to the firewall to instruct the firewall to prevent further communications into the network by the intrusive source. An Ethernet switch or field programmable gate array (FPGA) is incorporated in the security tap to coordinate the transmission of the “kill” data packet to avoid data collisions with data transmissions already existing in the communication line.
