Abstract:
A network attack defense policy sending method and apparatus are presented. The method includes receiving attack information which includes a target Internet Protocol (IP) address, and the attack information is used to indicate that a network attack packet whose destination address is the target IP address exists in a first network; determining that the network attack packet enters the first network through a first edge network device, where the first edge network device is an edge device in the first network; sending a defense policy to the first edge network device, where the defense policy is used to instruct the first edge network device to process, according to the defense policy, a packet whose destination address is the target IP address. By means of this application, network resources occupied by a network attack packet can be reduced, and an effect of defending against the network attack packet can be improved.
