发明名称 COMPUTER SYSTEM, CONTROLLER, AND NETWORK MONITORING METHOD
摘要 <p>Security intensity against illegal access and interruption using spoofed address is made to be improved. The computer system of the present invention includes: a controller; a switch configured to perform, on a received packet complying with a flow entry set by the controller, a relay operation regulated by the flow entry; and a host terminal configured to be connected to the switch. The switch notifies the controller of transmission source address information of a received packet which does not comply with a flow entry set to itself. The controller judges, when legal address information of a host terminal does not coincide with the transmission source address information, that a transmission source address of the received packet is spoofed.</p>
