Secure intrusion detection system

A network security device in communication with an Internet, comprising:

• a) a housing having an internal surface and an external surface, the internal surface encasing circuitry for receiving data from the Internet and forwarding the received data to a router and a network operations center, wherein the data is forwarded to the router and the network operations center via straight through connections, whereby the network security device is invisible to devices on the Internet and thereby prevents attacks via the Internet;
• b) a line in port on the external surface of the housing for accepting an Internet connection line, the Internet connection line configured to transfer data between the Internet and the network security device;
• c) a line out port on the external surface of the housing for completing a path between the Internet and the network security device;
• and
• d) a direct administration line on the external surface of the housing for providing a direct link to the network operations center.
