Abstract
A malicious attack detection method includes: receiving, by a controller, a Packet-in message sent by a switch, where the Packet-in message includes a source host identifier and a destination host identifier of a data packet for which the switch does not find a flow entry; when determining that a host indicated by the destination host identifier does not exist in an SDN network, sending, by the controller, an abnormal flow entry to the switch; receiving, by the controller, a triggering count sent by the switch, where the triggering count is a quantity of times that the abnormal flow entry is triggered; and determining, according to the triggering count, whether a malicious attack is initiated. According to the method, a malicious attack from a host can be detected, a data processing volume of a controller can be reduced, and performance of the controller can be improved.
